This thesis is guided by the following question: what, if anything, makes a life meaningful? My answer to this question is asymmetric welfarism about meaning in life. According to asymmetric welfarism, the meaning of a life depends upon two factors. First, a life is conferred meaning insofar as it promotes or protects the well-being of other welfare subjects. Second, a life is made meaningless insofar as it decreases or minimises the well-being of other welfare subjects. The meaning of a life is determined by the net balance between these two factors; the more the good outweighs the bad, the more meaningful a life that is. I argue that asymmetric welfarism is the most plausible theory about meaning in life. To do this, I show how such a view captures a variety of intuitions about meaning in life while defending it from objections. This is the business of chapters 1, 2, and 3. Specifically, chapter 1 lays the groundwork, chapter 2 advances the case in favour of asymmetric welfarism, while chapter 3 defends asymmetric welfarism from objections. But some objections cannot be so easily overturned by a mere argument. Such objections do not just count against asymmetric welfarism, but also support competing theories. In order to overcome both, I show how such objections, and the theories they motivate, are best understood as tracking a different, but related, evaluative dimension a life can have. This is the business of chapters 4, 5, and 6. Specifically, chapter 4 argues that subjective theories are best understood as being about fulfilment, chapter 5 argues that purpose theories are best understood as being about purpose, and chapter 6 argues that differing views about the role of morality confuse morality and significance with meaning. These other evaluative dimensions which stand alongside meaning in life are fulfilment, purpose, significance, morality, and prudential value.

What, if anything, makes a life meaningful? Consequentialist theories about meaning in life maintain that the consequences of that life confer meaning upon it. This article advances one such theory: welfarism about meaning in life. According to this view, a life is conferred meaning if, and only if, and then only insofar as, it promotes or protects the well‐being of other welfare subjects. The purpose of this article is to show why welfarism about meaning in life is the most plausible theory about meaning in life.

What is the relationship between meaning in life and luck? One popular view within the literature is that resultant luck vitiates meaning; that if the relevant state-of-affairs is primarily the result of luck, chance, or happenstance, rather than the person’s actions, then no meaning is conferred. Call this the anti-luck constraint. In this article it is argued that we should reject the anti-luck constraint. Two types of cases, often cited as examples in favour of the anti-luck constraint, are examined: the lucky idiot and the incompetent villain. Such lives, it is contended, can be meaningful even when the relevant states-of-affairs are primarily the product of resultant luck.

Can a moral monster - a person whose life is characterised by immoral actions - live a meaningful life? Pre-theoretical intuitions appear divided. For some, moral monsters can't live a meaningful life because they were immoral, while for others they did because morality is irrelevant. So what is the relationship between morality and meaning? This article contends that both sides are partially correct but for the wrong reasons: moral monsters don’t live meaningful lives, but morality is irrelevant for meaning. First, it is argued moral monsters live meaningless lives not because of immoral actions per se, but rather the harm they cause. Second, that moral monsters can live meaningful lives confuses meaningfulness with significance. Significance, I propose, is conferred upon a life when one's actions impact others' well-being for good or ill. On the view, moral monsters live meaningless but significant lives.

It is widely held that for a life to be conferred meaning it requires the appropriate type of agency. Call this the agency requirement. The agency requirement is primarily motivated in the philosophical literature by the assumption that there is a widespread pre-theoretical intuition that humans have the capacity for meaning whereas animals do not; and that difference must come down to their agency or lack thereof. This paper aims to undercut the motivation for the agency requirement by arguing our pre-theoretical intuitions actually run opposite; that animals, and even objects, can have meaningful lives/existences. The argument is twofold. First, I extend an existing argument for animals as having a capacity for meaning to objects. Second, I argue maintaining that only humans have the capacity for meaning results in the more counterintuitive upshot that all animals and objects have, by definition, meaningless existences. Since we pre-theoretically believe that anything can be meaningful—even things which by definition lack agency—then we have strong reason for being sceptical about an agency requirement for meaning in life.

While Nozick and his sympathizers assume there is a widespread anti-hedonist intuition to prefer reality to an experience machine, hedonists have marshalled empirical evidence that shows such an assumption to be unfounded. Results of several experience machine variants indicate there is no widespread anti-hedonist intuition. From these findings, hedonists claim Nozick's argument fails as an objection to hedonism. This article suggests the argument surrounding experience machines has been misconceived. Rather than eliciting intuitions about what is prudentially valuable, these intuitive judgements are instead calculations about prudential pay-offs and trade-offs. This position can help explain the divergence of intuitions people have about experience machines.
