What is good, how do we know, and how important is it? In this book, one of our most respected analytical philosophers reorients these questions around the notion of what causes human beings to flourish. Observing that we can sensibly address what is good for plants and animals no less than what is good for people, Kraut applies a general principle to the entire living world: what is good for complex organisms consists in the exercise of their natural powers.

Perfectionism, the view that well-being is a matter of developing characteristically human capacities, has relatively few defenders in the literature, but plenty of critics. This paper defends perfectionism against some recent formulations of classic objections, namely, the objection that perfectionism ignores the relevance of pleasure or preference for well-being, and a sophisticated version of the ‘wrong properties’ objection, according to which the intuitive plausibility of the perfectionist ideal is threatened by an absence of theoretical pressure to accept putative wrong properties (...) cases. The paper argues these objections are unsuccessful, but introduce a new worry, the Deep Problem: Perfectionism fails to offer a satisfying foundational justification for why developing the human essence is valuable. The paper responds to the deep problem, ultimately arguing that it is a puzzle put to all theories of well-being to provide a justification for their normative significance. (shrink)

So-called theories of well-being (prudential value, welfare) are under-represented in discussions of well-being. I do four things in this article to redress this. First, I develop a new taxonomy of theories of well-being, one that divides theories in a more subtle and illuminating way. Second, I use this taxonomy to undermine some misconceptions that have made people reluctant to hold objective-list theories. Third, I provide a new objective-list theory and show that it captures a powerful motivation for the main competitor (...) theory of well-being (the desire-fulfilment theory). Fourth, I try to defuse the worry that objective-list theories are problematically arbitrary and show how the theory can and should be developed. (shrink)

Many philosophers find welfare perfectionism implausible because it is arguably underinclusive, as it fails to count as good certain acts, events, and things that intuitively improve one's quality of life. Likewise, philosophers intuit that the experience of pleasure directly contributes to well-being. The problem for welfare perfectionism is straightforward: neither desire-satisfaction nor the experience of pleasure seem to perfect one's nature. This leaves two options for the welfare perfectionist. He can “bite the bullet” and argue that these intuitions are mistaken (...) and that pleasure and desire-satisfaction don't impact well-being. Alternatively, he can explain how such intuitive goods can directly contribute to well-being, despite initial appearances. I advance the latter approach. I argue that at least for some perfectionists, desire-satisfaction and pleasure both directly contribute to well-being. One cannot argue that welfare perfectionism necessarily neglects the intuitive importance of desire-satisfaction and pleasure. (shrink)

The old scholastic principle of the "convertibility" of being and goodness strikes nearly all moderns as either barely comprehensible or plain false. "Convertible" is a term of art meaning "interchangeable" in respect of predication, where the predicates can be exchanged salva veritate albeit not salva sensu: their referents are, as the maxim goes, really the same albeit conceptually different. The principle seems, at first blush, absurd. Did the scholastics literally mean that every being is good? Is that supposed to include (...) a cancer, a malaria parasite, an earthquake that kills millions? If every being is good, then no being is bad—but how can that be? To the contemporary philosophical mind, such bafflement is understandable. It derives from the systematic dismantling of the great scholastic edifice that took place over half a millennium. With the loss of the basic concepts out of which that edifice was built, the space created by those concepts faded out of existence as well. The convertibility principle, like virtually all the other scholastic principles (not all, since some do survive and thrive in analytic philosophy), could not persist in a post-scholastic space wholly alien to it.

Continues the discussion of theoretical and practical perfection by examining the considerations that give some beliefs and intentions more quality and therefore value than others. It argues that Aristotelian considerations about rationality as essential to humans require measures of quality to be formal, considering only formal properties of beliefs and ends rather than their substantive content. There are two such measures: the extent of a belief's or end's content in space, time, and objects involved, and the degree to which different (...) beliefs and ends are organized in a hierarchical structure. Together, these measures value explanatorily organized knowledge, a unified life, and complex, difficult activities such as games. (shrink)
