Hello!

Receiving the subject error in my code when calling [processedtext].dates().json() (the #json command itself causes the error).

I can post a test if you like, but I'm also noticing it in the observable docs, which may be another vector to the issue.

https://observablehq.com/@spencermountain/compromise-dates#cell-129

Also I'll add that this surprised me because I've been using this system for a number of weeks (it's parsing various documents) and this just happened on a new document added today, and doesn't happen against any other document I've processed so far. Some light debugging showed me that the size of the #ptrs dictionary is much much longer for this particular document (it found hundreds of date matches, where previous documents never had more than 50 or so items). I don't know if that is relevant, but maybe worth mentioning.

Thanks!

[spencermountain]

thanks Sandro, ya can you post a test?
The last release (3.6.0) was 2 months ago, but perhaps there is a scaling problem on large documents. That is possible

happy to debug it, if you can send me something to reproduce.
Will take a look at the observable issue, too
cheers

1. THE MEANING OF "MEANING" One of the field's aims consists of the systematic attempt to identify what people (essentially or characteristically) have in mind when they think about the topic of life's meaning. For many in the field, terms such as "importance" and "significance" are synonyms of "meaningfulness" and so are insufficiently revealing, but there are those who draw a distinction between meaningfulness and significance (Singer 1996, 11218 Belliotti 2019, 14550, 186). There is also debate about how the concept of a meaningless life relates to the ideas of a life that is absurd (Nagel 1970, 1986, 21423 Feinberg 1980 Belliotti 2019), futile (Trisel 2002), and not worth living (Landau 2017, 1215 Matheson 2017). A useful way to begin to get clear about what thinking about life's meaning involves is to specify the bearer. Which life does the inquirer have in mind? A standard distinction to draw is between the meaning "in" life, where a human person is what can exhibit meaning, and the meaning "of" life in a narrow sense, where the human species as a whole is what can be meaningful or not. There has also been a bit of recent consideration of whether animals or human infants can have meaning in their lives, with most rejecting that possibility (e.g., Wong 2008, 131, 147 Fischer 2019, 124), but a handful of others beginning to make a case for it (Purves and Delon 2018 Thomas 2018). Also underexplored is the issue of whether groups, such as a people or an organization, can be bearers of meaning, and, if so, under what conditions. Most analytic philosophers have been interested in meaning in life, that is, in the meaningfulness that a person's life could exhibit, with comparatively few these days addressing the meaning of life in the narrow sense. Even those who believe that God is or would be central to life's meaning have lately addressed how an individual's life might be meaningful in virtue of God more often than how the human race might be. Although some have argued that the meaningfulness of human life as such merits inquiry to no less a degree (if not more) than the meaning in a life (Seachris 2013 Tartaglia 2015 cf. Trisel 2016), a large majority of the field has instead been interested in whether their lives as individual persons (and the lives of those they care about) are meaningful and how they could become more so. Focusing on meaning in life, it is quite common to maintain that it is conceptually something good for its own sake or, relatedly, something that provides a basic reason for action (on which see Visak 2017). There are a few who have recently suggested otherwise, maintaining that there can be neutral or even undesirable kinds of meaning in a person's life (e.g., Mawson 2016, 90, 193 Thomas 2018, 291, 294). However, these are outliers, with most analytic philosophers, and presumably laypeople, instead wanting to know when an individual's life exhibits a certain kind of final value (or noninstrumental reason for action). Another claim about which there is substantial consensus is that meaningfulness is not all or nothing and instead comes in degrees, such that some periods of life are more meaningful than others and that some lives as a whole are more meaningful than others. Note that one can coherently hold the view that some people's lives are less meaningful (or even in a certain sense less "important") than others, or are even meaningless (unimportant), and still maintain that people have an equal standing from a moral point of view. Consider a consequentialist moral principle according to which each individual counts for one in virtue of having a capacity for a meaningful life, or a Kantian approach according to which all people have a dignity in virtue of their capacity for autonomous decisionmaking, where meaning is a function of the exercise of this capacity. For both moral outlooks, we could be required to help people with relatively meaningless lives. Yet another relatively uncontroversial element of the concept of meaningfulness in respect of individual persons is that it is logically distinct from happiness or rightness (emphasized in Wolf 2010, 2016). First, to ask whether someone's life is meaningful is not one and the same as asking whether her life is pleasant or she is subjectively well off. A life in an experience machine or virtual reality device would surely be a happy one, but very few take it to be a prima facie candidate for meaningfulness (Nozick 1974: 4245). Indeed, a number would say that one's life logically could become meaningful precisely by sacrificing one's wellbeing, e.g., by helping others at the expense of one's selfinterest. Second, asking whether a person's existence over time is meaningful is not identical to considering whether she has been morally upright there are intuitively ways to enhance meaning that have nothing to do with right action or moral virtue, such as making a scientific discovery or becoming an excellent dancer. Now, one might argue that a life would be meaningless if, or even because, it were unhappy or immoral, but that would be to posit a synthetic, substantive relationship between the concepts, far from indicating that speaking of "meaningfulness" is analytically a matter of connoting ideas regarding happiness or rightness. The question of what (if anything) makes a person's life meaningful is conceptually distinct from the questions of what makes a life happy or moral, although it could turn out that the best answer to the former question appeals to an answer to one of the latter questions. Supposing, then, that talk of "meaning in life" connotes something good for its own sake that can come in degrees and that is not analytically equivalent to happiness or rightness, what else does it involve? What more can we say about this final value, by definition? Most contemporary analytic philosophers would say that the relevant value is absent from spending time in an experience machine (but see Goetz 2012 for a different view) or living akin to Sisyphus, the mythic figure doomed by the Greek gods to roll a stone up a hill for eternity (famously discussed by Albert Camus and Taylor 1970). In addition, many would say that the relevant value is typified by the classic triad of "the good, the true, and the beautiful" (or would be under certain conditions). These terms are not to be taken literally, but instead are rough catchwords for beneficent relationships (love, collegiality, morality), intellectual reflection (wisdom, education, discoveries), and creativity (particularly the arts, but also potentially things like humor or gardening). Pressing further, is there something that the values of the good, the true, the beautiful, and any other logically possible sources of meaning involve? There is as yet no consensus in the field. One salient view is that the concept of meaning in life is a cluster or amalgam of overlapping ideas, such as fulfilling higherorder purposes, meriting substantial esteem or admiration, having a noteworthy impact, transcending one's animal nature, making sense, or exhibiting a compelling lifestory (Markus 2003 Thomson 2003 Metz 2013, 2435 Seachris 2013, 34 Mawson 2016). However, there are philosophers who maintain that something much more monistic is true of the concept, so that (nearly) all thought about meaningfulness in a person's life is essentially about a single property. Suggestions include being devoted to or in awe of qualitatively superior goods (Taylor 1989, 324), transcending one's limits (Levy 2005), or making a contribution (Martela 2016). Recently there has been something of an "interpretive turn" in the field, one instance of which is the strong view that meaningtalk is logically about whether and how a life is intelligible within a wider frame of reference (Goldman 2018, 11629 Seachris 2019 Thomas 2019 cf. Repp 2018). According to this approach, inquiring into life's meaning is nothing other than seeking out sensemaking information, perhaps a narrative about life or an explanation of its source and destiny. This analysis has the advantage of promising to unify a wide array of uses of the term "meaning." However, it has the disadvantages of being unable to capture the intuitions that meaning in life is essentially good for its own sake (Landau 2017, 1215), that it is not logically contradictory to maintain that an ineffable condition is what confers meaning on life (as per Cooper 2003, 12642 BennettHunter 2014 Waghorn 2014), and that often human actions themselves (as distinct from an interpretation of them), such as rescuing a child from a burning building, are what bear meaning. Some thinkers have suggested that a complete analysis of the concept of life's meaning should include what has been called "antimatter" (Metz 2002, 80507, 2013, 6365, 7173) or "antimeaning" (Campbell and Nyholm 2015 Egerstrom 2015), conditions that reduce the meaningfulness of a life. The thought is that meaning is well represented by a bipolar scale, where there is a dimension of not merely positive conditions, but also negative ones. Gratuitous cruelty or destructiveness are prima facie candidates for actions that not merely fail to add meaning, but also subtract from any meaning one's life might have had. Despite the ongoing debates about how to analyze the concept of life's meaning (or articulate the definition of the phrase "meaning in life"), the field remains in a good position to make progress on the other key questions posed above, viz., of what would make a life meaningful and whether any lives are in fact meaningful. A certain amount of common ground is provided by the point that meaningfulness at least involves a gradient final value in a person's life that is conceptually distinct from happiness and rightness, with exemplars of it potentially being the good, the true, and the beautiful. The rest of this discussion addresses philosophical attempts to capture the nature of this value theoretically and to ascertain whether it exists in at least some of our lives. 2. SUPERNATURALISM Most analytic philosophers writing on meaning in life have been trying to develop and evaluate theories, i.e., fundamental and general principles, that are meant to capture all the particular ways that a life could obtain meaning. As in moral philosophy, there are recognizable "antitheorists," i.e., those who maintain that there is too much pluralism among meaning conditions to be able to unify them in the form of a principle (e.g., Kekes 2000 Hosseini 2015). Arguably, though, the systematic search for unity is too nascent to be able to draw a firm conclusion about whether it is available. The theories are standardly divided on a metaphysical basis, that is, in terms of which kinds of properties are held to constitute the meaning. Supernaturalist theories are views according to which a spiritual realm is central to meaning in life. Most Western philosophers have conceived of the spiritual in terms of God or a soul as commonly understood in the Abrahamic faiths (but see Mulgan 2015 for discussion of meaning in the context of a God uninterested in us). In contrast, naturalist theories are views that the physical world as known particularly well by the scientific method is central to life's meaning. There is logical space for a nonnaturalist theory, according to which central to meaning is an abstract property that is neither spiritual nor physical. However, only scant attention has been paid to this possibility in the recent AngloAmericanAustralasian literature (Audi 2005). It is important to note that supernaturalism, a claim that God (or a soul) would confer meaning on a life, is logically distinct from theism, the claim that God (or a soul) exists. Although most who hold supernaturalism also hold theism, one could accept the former without the latter (as Camus more or less did), committing one to the view that life is meaningless or at least lacks substantial meaning. Similarly, while most naturalists are atheists, it is not contradictory to maintain that God exists but has nothing to do with meaning in life or perhaps even detracts from it. Although these combinations of positions are logically possible, some of them might be substantively implausible. The field could benefit from discussion of the comparative attractiveness of various combinations of evaluative claims about what would make life meaningful and metaphysical claims about whether spiritual conditions exist. Over the past 15 years or so, two different types of supernaturalism have become distinguished on a regular basis (Metz 2019). That is true not only in the literature on life's meaning, but also in that on the related protheismantitheism debate, about whether it would be desirable for God or a soul to exist (e.g., Kahane 2011 Kraay 2018 Lougheed 2020). On the one hand, there is extreme supernaturalism, according to which spiritual conditions are necessary for any meaning in life. If neither God nor a soul exists, then, by this view, everyone's life is meaningless. On the other hand, there is moderate supernaturalism, according to which spiritual conditions are necessary for a great or ultimate meaning in life, although not meaning in life as such. If neither God nor a soul exists, then, by this view, everyone's life could have some meaning, or even be meaningful, but no one's life could exhibit the most desirable meaning. For a moderate supernaturalist, God or a soul would substantially enhance meaningfulness or be a major contributory condition for it. There are a variety of ways that great or ultimate meaning has been described, sometimes quantitatively as "infinite" (Mawson 2016), qualitatively as "deeper" (Swinburne 2016), relationally as "unlimited" (Nozick 1981, 61819 cf. Waghorn 2014), temporally as "eternal" (Cottingham 2016), and perspectivally as "from the point of view of the universe" (Benatar 2017). There has been no reflection as yet on the crucial question of how these distinctions might bear on each another, for instance, on whether some are more basic than others or some are more valuable than others. Crosscutting the extrememoderate distinction is one between Godcentered theories and soulcentered ones. According to the former, some kind of connection with God (understood to be a spiritual person who is allknowing, allgood, and allpowerful and who is the ground of the physical universe) constitutes meaning in life, even if one lacks a soul (construed as an immortal, spiritual substance that contains one's identity). In contrast, by the latter, having a soul and putting it into a certain state is what makes life meaningful, even if God does not exist. Many supernaturalists of course believe that God and a soul are jointly necessary for a (greatly) meaningful existence. However, the simpler view, that only one of them is necessary, is common, and sometimes arguments proffered for the complex view fail to support it any more than the simpler one. 2.1. GODCENTERED VIEWS The most influential Godbased account of meaning in life has been the extreme view that one's existence is significant if and only if one fulfills a purpose God has assigned. The familiar idea is that God has a plan for the universe and that one's life is meaningful just to the degree that one helps God realize this plan, perhaps in a particular way that God wants one to do so. If a person failed to do what God intends her to do with her life (or if God does not even exist), then, on the current view, her life would be meaningless. Thinkers differ over what it is about God's purpose that might make it uniquely able to confer meaning on human lives, but the most influential argument has been that only God's purpose could be the source of invariant moral rules (Davis 1987, 296, 30405 Moreland 1987, 12429 Craig 19942013, 16167) or of objective values more generally (Cottingham 2005, 3757), where a lack of such would render our lives nonsensical. According to this argument, lower goods such as animal pleasure or desire satisfaction could exist without God, but higher ones pertaining to meaning in life, particularly moral virtue, could not. However, critics point to many nonmoral sources of meaning in life (e.g., Kekes 2000 Wolf 2010), with one arguing that a universal moral code is not necessary for meaning in life, even if, say, beneficent actions are (Ellin 1995, 327). In addition, there are a variety of naturalist and nonnaturalist accounts of objective morality -  - and of value more generally -  - on offer these days, so that it is not clear that it must have a supernatural source in God's will. One recurrent objection to the idea that God's purpose could make life meaningful is that if God had created us with a purpose in mind, then God would have degraded us and thereby undercut the possibility of us obtaining meaning from fulfilling the purpose. The objection harks back to JeanPaul Sartre, but in the analytic literature it appears that Kurt Baier was the first to articulate it (19572000, 11820 see also Murphy 1982, 1415 Singer 1996, 29 Kahane 2011 Lougheed 2020, 12141). Sometimes the concern is the threat of punishment God would make so that we do God's bidding, while other times it is that the source of meaning would be constrictive and not up to us, and still other times it is that our dignity would be maligned simply by having been created with a certain end in mind (for some replies to such concerns, see Hanfling 1987, 4546 Cottingham 2005, 3757 Lougheed 2020, 11121). There is a different argument for an extreme Godbased view that focuses less on God as purposive and more on God as infinite, unlimited, or ineffable, which Robert Nozick first articulated with care (Nozick 1981, 594618 see also BennettHunter 2014 Waghorn 2014). The core idea is that for a finite condition to be meaningful, it must obtain its meaning from another condition that has meaning. So, if one's life is meaningful, it might be so in virtue of being married to a person, who is important. Being finite, the spouse must obtain his or her importance from elsewhere, perhaps from the sort of work he or she does. This work also must obtain its meaning by being related to something else that is meaningful, and so on. A regress on meaningful conditions is present, and the suggestion is that the regress can terminate only in something so allencompassing that it need not (indeed, cannot) go beyond itself to obtain meaning from anything else. And that is God. The standard objection to this relational rationale is that a finite condition could be meaningful without obtaining its meaning from another meaningful condition. Perhaps it could be meaningful in itself, without being connected to something beyond it, or maybe it could obtain its meaning by being related to something else that is beautiful or otherwise valuable for its own sake but not meaningful (Nozick 1989, 16768 Thomson 2003, 2526, 48). A serious concern for any extreme Godbased view is the existence of apparent counterexamples. If we think of the stereotypical lives of Albert Einstein, Mother Teresa, and Pablo Picasso, they seem meaningful even if we suppose there is no allknowing, allpowerful, and allgood spiritual person who is the ground of the physical world (e.g., Wielenberg 2005, 3137, 4950 Landau 2017). Even religiously inclined philosophers have found this hard to deny these days (Quinn 2000, 58 Audi 2005 Mawson 2016, 5 Williams 2020, 13234). Largely for that reason, contemporary supernaturalists have tended to opt for moderation, that is, to maintain that God would greatly enhance the meaning in our lives, even if some meaning would be possible in a world without God. One approach is to invoke the relational argument to show that God is necessary, not for any meaning whatsoever, but rather for an ultimate meaning. "Limited transcendence, the transcending of our limits so as to connect with a wider context of value which itself is limited, does give our lives meaning -  - but a limited one. We may thirst for more" (Nozick 1981, 618). Another angle is to appeal to playing a role in God's plan, again to claim, not that it is essential for meaning as such, but rather for "a cosmic significance....intead of a significance very limited in time and space" (Swinburne 2016, 154 see also Quinn 2000 Cottingham 2016, 131). Another rationale is that by fulfilling God's purpose, we would meaningfully please God, a perfect person, as well as be remembered favorably by God forever (Cottingham 2016, 135 Williams 2020, 2122, 29, 101, 108). Still another argument is that only with God could the deepest desires of human nature be satisfied (e.g., Goetz 2012 Seachris 2013, 20 Cottingham 2016, 127, 136), even if more surface desires could be satisfied without God. In reply to such rationales for a moderate supernaturalism, there has been the suggestion that it is precisely by virtue of being alone in the universe that our lives would be particularly significant otherwise, God's greatness would overshadow us (Kahane 2014). There has also been the response that, with the opportunity for greater meaning from God would also come that for greater antimeaning, so that it is not clear that a world with God would offer a net gain in respect of meaning (Metz 2019, 3435). For example, if pleasing God would greatly enhance meaning in our lives, then presumably displeasing God would greatly reduce it and to a comparable degree. In addition, there are arguments for extreme naturalism (or its "antitheist" cousin) mentioned below (subsection 3.3). 2.2. SOULCENTERED VIEWS Notice that none of the above arguments for supernaturalism appeals to the prospect of eternal life (at least not explicitly). Arguments that do make such an appeal are soulcentered, holding that meaning in life mainly comes from having an immortal, spiritual substance that is contiguous with one's body when it is alive and that will forever outlive its death. Some think of the afterlife in terms of one's soul entering a transcendent, spiritual realm (Heaven), while others conceive of one's soul getting reincarnated into another body on Earth. According to the extreme version, if one has a soul but fails to put it in the right state (or if one lacks a soul altogether), then one's life is meaningless. There are three prominent arguments for an extreme soulbased perspective. One argument, made famous by Leo Tolstoy, is the suggestion that for life to be meaningful something must be worth doing, that something is worth doing only if it will make a permanent difference to the world, and that making a permanent difference requires being immortal (see also Hanfling 1987, 2224 Morris 1992, 26 Craig 1994). Critics most often appeal to counterexamples, suggesting for instance that it is surely worth your time and effort to help prevent people from suffering, even if you and they are mortal. Indeed, some have gone on the offensive and argued that helping people is worth the sacrifice only if and because they are mortal, for otherwise they could invariably be compensated in an afterlife (e.g., Wielenberg 2005, 9194). Another recent and interesting criticism is that the major motivations for the claim that nothing matters now if one day it will end are incoherent (Greene 2021). A second argument for the view that life would be meaningless without a soul is that it is necessary for justice to be done, which, in turn, is necessary for a meaningful life. Life seems nonsensical when the wicked flourish and the righteous suffer, at least supposing there is no other world in which these injustices will be rectified, whether by God or a Karmic force. Something like this argument can be found in Ecclesiastes, and it continues to be defended (e.g., Davis 1987 Craig 1994). However, even granting that an afterlife is required for perfectly just outcomes, it is far from obvious that an eternal afterlife is necessary for them, and, then, there is the suggestion that some lives, such as Mandela's, have been meaningful precisely in virtue of encountering injustice and fighting it. A third argument for thinking that having a soul is essential for any meaning is that it is required to have the sort of free will without which our lives would be meaningless. Immanuel Kant is known for having maintained that if we were merely physical beings, subjected to the laws of nature like everything else in the material world, then we could not act for moral reasons and hence would be unimportant. More recently, one theologian has eloquently put the point in religious terms: "The moral spirit finds the meaning of life in choice. It finds it in that which proceeds from man and remains with him as his inner essence rather than in the accidents of circumstances turns of external fortune....(W)henever a human being rubs the lamp of his moral conscience, a Spirit does appear. This Spirit is God....It is in the 'Thou must' of God and man's 'I can' that the divine image of God in human life is contained" (Swenson 19492000, 2728). Notice that, even if moral norms did not spring from God's commands, the logic of the argument entails that one's life could be meaningful, so long as one had the inherent ability to make the morally correct choice in any situation. That, in turn, arguably requires something nonphysical about one's self, so as to be able to overcome whichever physical laws and forces one might confront. The standard objection to this reasoning is to advance a compatibilism about having a determined physical nature and being able to act for moral reasons (e.g., Arpaly 2006 Fischer 2009, 14577). It is also worth wondering whether, if one had to have a spiritual essence in order to make free choices, it would have to be one that never perished. Like Godcentered theorists, many soulcentered theorists these days advance a moderate view, accepting that some meaning in life would be possible without immortality, but arguing that a much greater meaning would be possible with it. Granting that Einstein, Mandela, and Picasso had somewhat meaningful lives despite not having survived the deaths of their bodies (as per, e.g., Trisel 2004 Wolf 2015, 89140 Landau 2017), there remains a powerful thought: more is better. If a finite life with the good, the true, and the beautiful has meaning in it to some degree, then surely it would have all the more meaning if it exhibited such higher values -  - including a relationship with God -  - for an eternity (Cottingham 2016, 13235 Mawson 2016, 2019, 5253 Williams 2020, 11234 cf. Benatar 2017, 3563). One objection to this reasoning is that the infinity of meaning that would be possible with a soul would be "too big," rendering it difficult for the moderate supernaturalist to make sense of the intution that a finite life such as Einstein's can indeed count as meaningful by comparison (Metz 2019, 3031 cf. Mawson 2019, 5354). More common, though, is the objection that an eternal life would include antimeaning of various kinds, such as boredom and repetition, discussed below in the context of extreme naturalism (subsection 3.3). 3. NATURALISM Recall that naturalism is the view that a physical life is central to life's meaning, that even if there is no spiritual realm, a substantially meaningful life is possible. Like supernaturalism, contemporary naturalism admits of two distinguishable variants, moderate and extreme (Metz 2019). The moderate version is that, while a genuinely meaningful life could be had in a purely physical universe as known well by science, a somewhat more meaningful life would be possible if a spiritual realm also existed. God or a soul could enhance meaning in life, although they would not be major contributors. The extreme version of naturalism is the view that it would be better in respect of life's meaning if there were no spiritual realm. From this perspective, God or a soul would be antimatter, i.e., would detract from the meaning available to us, making a purely physical world (even if not this particular one) preferable. Crosscutting the moderateextreme distinction is that between subjectivism and objectivism, which are theoretical accounts of the nature of meaningfulness insofar as it is physical. They differ in terms of the extent to which the human mind constitutes meaning and whether there are conditions of meaning that are invariant among human beings. Subjectivists believe that there are no invariant standards of meaning because meaning is relative to the subject, i.e., depends on an individual's proattitudes such as her particular desires or ends, which are not shared by everyone. Roughly, something is meaningful for a person if she strongly wants it or intends to seek it out and she gets it. Objectivists maintain, in contrast, that there are some invariant standards for meaning because meaning is at least partly mindindependent, i.e., obtains not merely in virtue of being the object of anyone's mental states. Here, something is meaningful (partially) because of its intrinsic nature, in the sense of being independent of whether it is wanted or intended meaning is instead (to some extent) the sort of thing that merits these reactions. There is logical space for an orthogonal view, according to which there are invariant standards of meaningfulness constituted by what all human beings would converge on from a certain standpoint. However, it has not been much of a player in the field (Darwall 1983, 16466). 3.1. SUBJECTIVISM According to this version of naturalism, meaning in life varies from person to person, depending on each one's variable proattitudes. Common instances are views that one's life is more meaningful, the more one gets what one happens to want strongly, achieves one's highly ranked goals, or does what one believes to be really important (Trisel 2002 Hooker 2008). One influential subjectivist has recently maintained that the relevant mental state is caring or loving, so that life is meaningful just to the extent that one cares about or loves something (Frankfurt 1988, 8094, 2004). Another recent proposal is that meaningfulness consists of "an active engagement and affirmation that vivifies the person who has freely created or accepted and now promotes and nurtures the projects of her highest concern" (Belliotti 2019, 183). Subjectivism was dominant in the middle of the twentieth century, when positivism, noncognitivism, existentialism, and Humeanism were influential (Ayer 1947 Hare 1957 Barnes 1967 Taylor 1970 Williams 1976). However, in the last quarter of the twentieth century, inference to the best explanation and reflective equilibrium became accepted forms of normative argumentation and were frequently used to defend claims about the existence and nature of objective value (or of "external reasons," ones obtaining independently of one's extant attitudes). As a result, subjectivism about meaning lost its dominance. Those who continue to hold subjectivism often remain suspicious of attempts to justify beliefs about objective value (e.g., Trisel 2002, 73, 79, 2004, 37879 Frankfurt 2004, 4748, 5557 Wong 2008, 13839 Evers 2017, 32, 36 Svensson 2017, 54). Theorists are moved to accept subjectivism typically because the alternatives are unpalatable they are reasonably sure that meaning in life obtains for some people, but do not see how it could be grounded on something independent of the mind, whether it be the natural or the supernatural (or the nonnatural). In contrast to these possibilities, it appears straightforward to account for what is meaningful in terms of what people find meaningful or what people want out of their lives. Wideranging metaethical debates in epistemology, metaphysics, and the philosophy of language are necessary to address this rationale for subjectivism. There is a cluster of other, more circumscribed arguments for subjectivism, according to which this theory best explains certain intuitive features of meaning in life. For one, subjectivism seems plausible since it is reasonable to think that a meaningful life is an authentic one (Frankfurt 1988, 8094). If a person's life is significant insofar as she is true to herself or her deepest nature, then we have some reason to believe that meaning simply is a function of those matters for which the person cares. For another, it is uncontroversial that often meaning comes from losing oneself, i.e., in becoming absorbed in an activity or experience, as opposed to being bored by it or finding it frustrating (Frankfurt 1988, 8094 Belliotti 2019, 16270). Work that concentrates the mind and relationships that are engrossing seem central to meaning and to be so because of the subjective elements involved. For a third, meaning is often taken to be something that makes life worth continuing for a specific person, i.e., that gives her a reason to get out of bed in the morning, which subjectivism is thought to account for best (Williams 1976 Svensson 2017 Calhoun 2018). Critics maintain that these arguments are vulnerable to a common objection: they neglect the role of objective value (or an external reason) in realizing oneself, losing oneself, and having a reason to live (Taylor 1989, 1992 Wolf 2010, 2015, 89140). One is not really being true to oneself, losing oneself in a meaningful way, or having a genuine reason to live insofar as one, say, successfully maintains 3,732 hairs on one's head (Taylor 1992, 36), cultivates one's prowess at longdistance spitting (Wolf 2010, 104), collects a big ball of string (Wolf 2010, 104), or, well, eats one's own excrement (Wielenberg 2005, 22). The counterexamples suggest that subjective conditions are insufficient to ground meaning in life there seem to be certain actions, relationships, and states that are objectively valuable (but see Evers 2017, 3032) and toward which one's proattitudes ought to be oriented, if meaning is to accrue. So say objectivists, but subjectivists feel the pull of the point and usually seek to avoid the counterexamples, lest they have to bite the bullet by accepting the meaningfulness of maintaining 3,732 hairs on one's head and all the rest (for some who do, see Svensson 2017, 5455 Belliotti 2019, 18183). One important strategy is to suggest that subjectivists can avoid the counterexamples by appealing to the right sort of proattitude. Instead of whatever an individual happens to want, perhaps the relevant mental state is an emotionalperceptual one of seeingas (Alexis 2011 cf. Hosseini 2015, 4766), a "categorical" desire, that is, an intrinsic desire constitutive of one's identity that one takes to make life worth continuing (Svensson 2017), or a judgment that one has a good reason to value something highly for its own sake (Calhoun 2018). Even here, though, objectivists will argue that it might "appear that whatever the will chooses to treat as a good reason to engage itself is, for the will, a good reason. But the will itself....craves objective reasons and often it could not go forward unless it thought it had them" (Wiggins 1988, 136). And without any appeal to objectivity, it is perhaps likely that counterexamples would resurface. Another subjectivist strategy by which to deal with the counterexamples is the attempt to ground meaningfulness, not on the proattitudes of an individual valuer, but on those of a group (Darwall 1983, 16466 Brogaard and Smith 2005 Wong 2008). Does such an intersubjective move avoid (more of) the counterexamples? If so, does it do so more plausibly than an objective theory? 3.2. OBJECTIVISM Objective naturalists believe that meaning in life is constituted at least in part by something physical beyond merely the fact that it is the object of a proattitude. Obtaining the object of some emotion, desire, or judgment is not sufficient for meaningfulness, on this view. Instead, there are certain conditions of the material world that could confer meaning on anyone's life, not merely because they are viewed as meaningful, wanted for their own sake, or believed to be choiceworthy, but instead (at least partially) because they are inherently worthwhile or valuable in themselves. Morality (the good), enquiry (the true), and creativity (the beautiful) are widely held instances of activities that confer meaning on life, while trimming toenails and eating snow -  - along with the counterexamples to subjectivism above -  - are not. Objectivism is widely thought to be a powerful general explanation of these particular judgments: the former are meaningful not merely because some agent (whether it is an individual, her society, or even God) cares about them or judges them to be worth doing, while the latter simply lack significance and cannot obtain it even if some agent does care about them or judge them to be worth doing. From an objective perspective, it is possible for an individual to care about the wrong thing or to be mistaken that something is worthwhile, and not merely because of something she cares about all the more or judges to be still more choiceworthy. Of course, metaethical debates about the existence and nature of value are again relevant to appraising this rationale. Some objectivists think that being the object of a person's mental states plays no constitutive role in making that person's life meaningful, although they of course contend that it often plays an instrumental role -  - liking a certain activity, after all, is likely to motivate one to do it. Relatively few objectivists are "pure" in that way, although consequentialists do stand out as clear instances (e.g., Singer 1995 Smuts 2018, 7599). Most objectivists instead try to account for the above intuitions driving subjectivism by holding that a life is more meaningful, not merely because of objective factors, but also in part because of propositional attitudes such as cognition, conation, and emotion. Particularly influential has been Susan Wolf's hybrid view, captured by this pithy slogan: "Meaning arises when subjective attraction meets objective attractiveness" (Wolf 2015, 112 see also Kekes 1986, 2000 Wiggins 1988 Raz 2001, 1040 Mintoff 2008 Wolf 2010, 2016 Fischer 2019, 923 Belshaw 2021, 16081). This theory implies that no meaning accrues to one's life if one believes in, is satisfied by, or cares about a project that is not truly worthwhile, or if one takes up a truly worthwhile project but fails to judge it important, be satisfied by it, or care about it. A related approach is that, while subjective attraction is not necessary for meaning, it could enhance it (e.g., Audi 2005, 344 Metz 2013, 18384, 19698, 22025). For instance, a stereotypical Mother Teresa who is bored by and alienated from her substantial charity work might have a somewhat significant existence because of it, even if she would have an even more significant existence if she felt pride in it or identified with it. There have been several attempts to capture theoretically what all objectively attractive, inherently worthwhile, or finally valuable conditions have in common insofar as they bear on meaning in a person's life. Over the past few decades, one encounters the proposals that objectively meaningful conditions are just those that involve: positively connecting with organic unity beyond oneself (Nozick 1981, 594619) being creative (Taylor 1987 Matheson 2018) living an emotional life (Solomon 1993 cf. Williams 2020, 5678) promoting good consequences, such as improving the quality of life of oneself and others (Singer 1995 Audi 2005 Smuts 2018, 7599) exercising or fostering rational nature in exceptional ways (Smith 1997, 179221 Gewirth 1998, 17782 Metz 2013, 22236) progressing toward ends that can never be fully realized because one's knowledge of them changes as one approaches them (Levy 2005) realizing goals that are transcendent for being longlasting in duration and broad in scope (Mintoff 2008) living virtuously (May 2015, 61138 McPherson 2020) and loving what is worth loving (Wolf 2016). There is as yet no convergence in the field on one, or even a small cluster, of these accounts. One feature of a large majority of the above naturalist theories is that they are aggregative or additive, objectionably treating a life as a mere "container" of bits of life that are meaningful considered in isolation from other bits (Brnnmark 2003, 330). It has become increasingly common for philosophers of life's meaning, especially objectivists, to hold that life as a whole, or at least long stretches of it, can substantially affect its meaningfulness beyond the amount of meaning (if any) in its parts. For instance, a life that has lots of beneficence and otherwise intuitively meaningconferring conditions but that is also extremely repetitive ( la the movie Groundhog Day) is less than maximally meaningful (Taylor 1987 Blumenfeld 2009). Furthermore, a life that not only avoids repetition but also ends with a substantial amount of meaningful (or otherwise desirable) parts seems to have more meaning overall than one that has the same amount of meaningful (desirable) parts but ends with few or none of them (Kamm 2013, 1822 Dorsey 2015). Still more, a life in which its meaningless (or otherwise undesirable parts) cause its meaningful (desirable) parts to come about through a process of personal growth seems meaningful in virtue of this redemptive pattern, "good lifestory," or narrative selfexpression (Taylor 1989, 4851 Wong 2008 Fischer 2009, 14577 Kauppinen 2012 May 2015, 61138 Velleman 2015, 14173). These three cases suggest that meaning can inhere in life as a whole, that is, in the relationships between its parts, and not merely in the parts considered in isolation. However, some would maintain that it is, strictly speaking, the story that is or could be told of a life that matters, not so much the lifestory qua relations between events themselves (de Bres 2018). There are pure or extreme versions of holism present in the literature, according to which the only possible bearer of meaning in life is a person's life as a whole, and not any isolated activities, relationships, or states (Taylor 1989, 4851 Tabensky 2003 Levinson 2004). A salient argument for this position is that judgments of the meaningfulness of a part of someone's life are merely provisional, open to revision upon considering how they fit into a wider perspective. So, for example, it would initially appear that taking an ax away from a madman and thereby protecting innocent parties confers some meaning on one's life, but one might well revise that judgment upon learning that the intention behind it was merely to steal an ax, not to save lives, or that the madman then took out a machine gun, causing much more harm than his ax would have. It is worth considering how far this sort of case is generalizable, and, if it can be to a substantial extent, whether that provides strong evidence that only life as a whole can exhibit meaningfulness. Perhaps most objectivists would, at least upon reflection, accept that both the parts of a life and the wholelife relationships among the parts can exhibit meaning. Supposing there are two bearers of meaning in a life, important questions arise. One is whether a certain narrative can be meaningful even if its parts are not, while a second is whether the meaningfulness of a part increases if it is an aspect of a meaningful whole (on which see Brnnmark 2003), and a third is whether there is anything revealing to say about how to make tradeoffs between the parts and whole in cases where one must choose between them (Blumenfeld 2009 appears to assign lexical priority to the whole). 3.3. REJECTING GOD AND A SOUL Naturalists until recently had been largely concerned to show that meaning in life is possible without God or a soul they have not spent much time considering how such spiritual conditions might enhance meaning, but have, in moderate fashion, tended to leave that possibility open (an exception is Hooker 2008). Lately, however, an extreme form of naturalism has arisen, according to which our lives would probably, if not unavoidably, have less meaning in a world with God or a soul than in one without. Although such an approach was voiced early on by Baier (1957), it is really in the past decade or so that this "antitheist" position has become widely and intricately discussed. One rationale, mentioned above as an objection to the view that God's purpose constitutes meaning in life, has also been deployed to argue that the existence of God as such would necessarily reduce meaning, that is, would consist of antimatter. It is the idea that masterservant and parentchild analogies so prominent in the monotheist religious traditions reveal something about our status in a world where there is a qualitatively higher being who has created us with certain ends in mind: our independence or dignity as adult persons would be violated (e.g., Baier 19572000, 11820 Kahane 2011, 68185 Lougheed 2020, 12141). One interesting objection to this reasoning has been to accept that God's existence is necessarily incompatible with the sort of meaning that would come (roughly stated) from being one's own boss, but to argue that God would also make greater sorts of meaning available, offering a net gain to us (Mawson 2016, 11058). Another salient argument for thinking that God would detract from meaning in life appeals to the value of privacy (Kahane 2011, 68185 Lougheed 2020, 55110). God's omniscience would unavoidably make it impossible for us to control another person's access to the most intimate details about ourselves, which, for some, amounts to a less meaningful life than one with such control. Beyond questioning the value of our privacy in relation to God, one thoughtprovoking criticism has been to suggest that, if a lack of privacy really would substantially reduce meaning in our lives, then God, qua morally perfect person, would simply avoid knowing everything about us (Tooley 2018). Lacking complete knowledge of our mental states would be compatible with describing God as "omniscient," so the criticism goes, insofar as that is plausibly understood as having as much knowledge as is morally permissible. Turn, now, to major arguments for thinking that having a soul would reduce life's meaning, so that if one wants a maximally meaningful life, one should prefer a purely physical world, or at least one in which people are mortal. First and foremost, there has been the argument that an immortal life could not avoid becoming boring (Williams 1973), rendering life pointless according to many subjective and objective theories. The literature on this topic has become enormous, with the central reply being that immortality need not get boring (for more recent discussions, see Fischer 2009, 79101, 2019, 11742 Mawson 2019, 5152 Williams 2020, 3041, 12329 Belshaw 2021, 18297). However, it might also be worth questioning whether boredom is sufficient for meaninglessness. Suppose, for instance, that one volunteers to be bored so that many others will not be bored perhaps this would be a meaningful sacrifice to make. Being bored for an eternity would not be blissful or even satisfying, to be sure, but if it served the function of preventing others from being bored for an eternity, would it be meaningful (at least to some degree)? If, as is commonly held, sacrificing one's life could be meaningful, why not also sacrificing one's liveliness? Another reason given to reject eternal life is that it would become repetitive, which would substantially drain it of meaning (Scarre 2007, 5455 May 2009, 4647, 6465, 71 Smuts 2011, 14244 cf. Blumenfeld 2009). If, as it appears, there are only a finite number of actions one could perform, relationships one could have, and states one could be in during an eternity, one would have to end up doing the same things again. Even though one's activities might be more valuable than rolling a stone up a hill forever  la Sisyphus, the prospect of doing them over and over again forever is disheartening for many. To be sure, one might not remember having done them before and hence could avoid boredom, but for some philosophers that would make it all the worse, akin to having dementia and forgetting that one has told the same stories. Others, however, still find meaning in such a life (e.g., Belshaw 2021, 197, 205n41). A third meaningbased argument against immortality invokes considerations of narrative. If the pattern of one's life as a whole substantially matters, and if a proper pattern would include a beginning, a middle, and an end, it appears that a life that never ends would lack the relevant narrative structure. "Because it would drag on endlessly, it would, sooner or later, just be a string of events lacking all form....With immortality, the novel never ends....How meaningful can such a novel be?" (May 2009, 68, 72 see also Scarre 2007, 5860). Notice that this objection is distinct from considerations of boredom and repetition (which concern novelty) even if one were stimulated and active, and even if one found a way not to repeat one's life in the course of eternity, an immortal life would appear to lack shape. In reply, some reject the idea that a meaningful life must be akin to a novel, and intead opt for narrativity in the form of something like a string of short stories that build on each other (Fischer 2009, 14577, 2019, 10116). Others, though, have sought to show that eternity could still be novellike, deeming the sort of ending that matters to be a function of what the content is and how it relates to the content that came before (e.g., Seachris 2011 Williams 2020, 11219). There have been additional objections to immortality as undercutting meaningfulness, but they are prima facie less powerful than the previous three in that, if sound, they arguably show that an eternal life would have a cost, but probably not one that would utterly occlude the prospect of meaning in it. For example, there have been the suggestions that eternal lives would lack a sense of preciousness and urgency (Nussbaum 1989, 339 Kass 2002, 26667), could not exemplify virtues such as courageously risking one's life for others (Kass 2002, 26768 Wielenberg 2005, 9194), and could not obtain meaning from sustaining or saving others' lives (Nussbaum 1989, 338 Wielenberg 2005, 9194). Note that at least the first two rationales turn substantially on the belief in immortality, not quite immortality itself: if one were immortal but forgot that one is or did not know that at all, then one could appreciate life and obtain much of the virtue of courage (and, conversely, if one were not immortal, but thought that one is, then, by the logic of these arguments, one would fail to appreciate limits and be unable to exemplify courage). 4. NIHILISM The previous two sections addressed theoretical accounts of what would confer meaning on a human person's life. Although these theories do not imply that some people's lives are in fact meaningful, that has been the presumption of a very large majority of those who have advanced them. Much of the procedure has been to suppose that many lives have had meaning in them and then to consider in virtue of what they have or otherwise could. However, there are nihilist (or pessimist) perspectives that question this supposition. According to nihilism (pessimism), what would make a life meaningful in principle cannot obtain for any of us. One straightforward rationale for nihilism is the combination of extreme supernaturalism about what makes life meaningful and atheism about whether a spiritual realm exists. If you believe that God or a soul is necessary for meaning in life, and if you believe that neither is real, then you are committed to nihilism, to the denial that life can have any meaning. Athough this rationale for nihilism was prominent in the modern era (and was more or less Camus' position), it has been on the wane in analytic philosophical circles, as extreme supernaturalism has been eclipsed by the moderate variety. The most common rationales for nihilism these days do not appeal to supernaturalism, or at least not explicitly. One cluster of ideas appeals to what metaethicists call "error theory," the view that evaluative claims (in this case about meaning in life, or about morality qua necessary for meaning) characteristically posit objectively real or universally justified values, but that such values do not exist. According to one version, value judgments often analytically include a claim to objectivity but there is no reason to think that objective values exist, as they "would be entities or qualities or relations of a very strange sort, utterly different from anything else in the universe" (Mackie 19771990, 38). According to a second version, life would be meaningless if there were no set of moral standards that could be fully justified to all rational enquirers, but it so happens that such standards cannot exist for persons who can always reasonably question a given claim (Murphy 1982, 1217). According to a third, we hold certain beliefs about the objectivity and universality of morality and related values such as meaning because they were evolutionarily advantageous to our ancestors, not because they are true. Humans have been "deceived by their genes into thinking that there is a distinterested, objective morality binding upon them, which all should obey" (Ruse and Wilson 1986, 179 cf. Street 2015). One must draw on the intricate work in metaethics that has been underway for the past several decades in order to appraise these arguments. In contrast to errortheoretic arguments for nihilism, there are rationales for it accepting that objective values exist but denying that our lives can ever exhibit or promote them so as to obtain meaning. One version of this approach maintains that, for our lives to matter, we must be in a position to add objective value to the world, which we are not since the objective value of the world is already infinite (Smith 2003). The key premises for this view are that every bit of spacetime (or at least the stars in the physical universe) have some positive value, that these values can be added up, and that space is infinite. If the physical world at present contains an infinite degree of value, nothing we do can make a difference in terms of meaning, for infinity plus any amount of value remains infinity. One way to question this argument, beyond doubting the value of spacetime or stars, is to suggest that, even if one cannot add to the value of the universe, meaning plausibly comes from being the source of certain values. A second rationale for nihilism that accepts the existence of objective value is David Benatar's (2006, 1859) intriguing "asymmetry argument" for antinatalism, the view that it is immoral to bring new people into existence because doing so would always be on balance bad for them. For Benatar, the bads of existing (e.g., pains) are real disadvantages relative to not existing, while the goods of existing (pleasures) are not real advantages relative to not existing, since there is in the latter state no one to be deprived of them. If indeed the state of not existing is no worse than that of experiencing the benefits of existence, then, since existing invariably brings harm in its wake, it follows that existing is always worse compared to not existing. Although this argument is illustrated with experiential goods and bads, it seems generalizable to nonexperiential ones, including meaning in life and antimatter. The literature on this argument has become large (for a recent collection, see Hauskeller and Hallich 2022). Benatar (2006, 6092, 2017, 3563) has advanced an additional argument for nihilism, one that appeals to Thomas Nagel's (1986, 20832) widely discussed analysis of the extremely external standpoint that human persons can take on their lives. There exists, to use Henry Sidgwick's influential phrase, the "point of view of the universe," that is, the standpoint that considers a human being's life in relation to all times and all places. When one takes up this most external standpoint and views one's puny impact on the world, little of one's life appears to matter. What one does in a certain society on Earth over 75 years or so just does not amount to much, when considering the billions of temporal years and billions of lightyears that make up spacetime. Although this reasoning grants limited kinds of meaning to human beings, from a personal, social, or human perspective, Benatar both denies that the greatest sort of meaning -  - a cosmic one -  - is available to them and contends that this makes their lives bad, hence the "nihilist" tag. Some have objected that our lives could in fact have a cosmic significance, say, if they played a role in God's plan (Quinn 2000, 6566 Swinburne 2016, 154), were the sole ones with a dignity in the universe (Kahane 2014), or engaged in valuable activities that could be appreciated by anyone anywhere anytime (Wolf 2016, 26162). Others naturally maintain that cosmic significance is irrelevant to appraising a human life, with some denying that it would be a genuine source of meaning (Landau 2017, 9399), and others accepting that it would be but maintaining that the absence of this good would not count as a bad or merit regret (discussed in Benatar 2017, 5662 Williams 2020, 10811). Finally, a distinguishable source of nihilism concerns the ontological, as distinct from axiological, preconditions for meaning in life. Perhaps most radically, there are those who deny that we have selves. Do we indeed lack selves, and, if we do, is a meaningful life impossible for us (see essays in Caruso and Flanagan 2018 Le Bihan 2019)? Somewhat less radically, there are those who grant that we have selves, but deny that they are in charge in the relevant way. That is, some have argued that we lack selfgovernance or free will of the sort that is essential for meaning in life, at least if determinism is true (Pisciotta 2013 essays in Caruso and Flanagan 2018). Nonquantum events, including human decisions, appear to be necessited by a prior state of the world, such that none could have been otherwise, and many of our decisions are a product of unconscious neurological mechanisms (while quantum events are of course utterly beyond our control). If none of our conscious choices could have been avoided and all were ultimately necessited by something external to them, perhaps they are insufficient to merit pride or admiration or to constitute narrative authorship of a life. In reply, some maintain that a compatibilism between determinism and moral responsibility applies with comparable force to meaning in life (e.g., Arpaly 2006 Fischer 2009, 14577), while others contend that incompatibilism is true of moral responsibility but not of meaning (Pereboom 2014).
