A number of scholars have recently defended the claim that there is a close connection between the evolutionary biological notion of fitness and the economic notion of utility: both are said to refer to an organism’s success in dealing with its environment, and both are said to play the same theoretical roles in their respective sciences. However, an analysis of two seemingly disparate but in fact structurally related phenomena—‘niche construction’ (the case where organisms change their environment to make it fit (...) to their needs) and ‘adaptive preferences’ (the case where agents change their wants to make them fit to what the world has given them)—shows that one needs to be very careful about the postulation of this sort of fitness–utility connection. Specifically, I here use the analysis of these two phenomena to establish when connecting fitness and utility is and is not possible. (shrink)

Typical justifications of prudence are based on the fact that we are temporally extended agents who remain numerically identical over time. After showing that prudential considerations should instead be based on our identity at a particular time, I outline a normative context for prudential reasons, based on a present commitment to temporal neutrality. I then consider how contingency in the content of a present commitment to temporal neutrality provides a flexible context that can help to resolve current debates about whether (...) agents are required to maximize value, maximin value, minimax loss or are required to conform to any of a host of other options on how to adjudicate various types of conflict between present and future values.

Preferences play a role in well-being that is difficult to escape, but whatever authority one grants to preferences, their malleability seems to cause problems for any theory of well-being that employs them. Most importantly, preferences appear to display a status-quo bias: people come to prefer what they are likely rather than unlikely to get. I try to do two things here. The first is to provide a more precise characterization of the status-quo bias, how it functions, and how it infects (...) commonly accepted theories of well-being. The second is to give an alternative characterization of an agent's preferences that succeeds in avoiding the status-quo bias. (shrink)

This dissertation is structured in such a way as to gradually home in on the true theory of welfare. I start with the whole field of possible theories of welfare and then proceed by narrowing down the options in a series of steps. The first step, undertaken in chapter 2, is to argue that the true theory of welfare must be what I call a partly response independent theory. First I reject the entirely response independent theories because there are widely-shared (...) intuitions suggesting that some psychological responses are indeed relevant to welfare. Then I reject the entirely response dependent theories because there are other central intuitions suggesting that our welfare is not determined solely by our psychological responses. Thus I reach the preliminary conclusion that welfare must involve some response independent (or objective) component. The next step is to consider the most promising theories in the partly response independent category. In particular, I formulate, refine and ultimately reject what seem to be the main monistic theories that have been proposed in this category. In chapter 4, I reject the Adjusted-Enjoyment Theories of Welfare because they cannot account for the claim that a life containing no pleasure or pain can still contain a positive amount of welfare (e.g. if it’s a particularly successful life). Then in chapters 5-7, I discuss Desire Satisfaction theories of welfare. I argue that even the most promising of these theories – e.g. Worthiness Adjusted Desire Satisfactionism – are problematic because they cannot accommodate the claim that a life containing no success with respect to worthwhile projects can still contain a positive amount of welfare (e.g. if it’s a particularly pleasant life). Finally, I suggest that in order to accommodate the intuitions that led to the rejection of all these other theories of welfare, what is needed is a multi-component theory. In the final chapter, I formulate a multi-component theory that is particularly promising. Not only does it avoid the problems of the monistic theories discussed earlier, but, by incorporating a number of novel mathematical devices, it avoids problems that undermine several other initially promising multi-component theories of welfare.

In this article, I aim to clarify how Actual Desire Satisfactionism should accommodate the ways in which desire and time are connected. In particular, I argue that Weak Concurrentism represents the most promising way for the Desire Satisfactionist to capture the temporal nature of desire. I consider the Desire Satisfactionist's other main options, but argue that none succeeds. This leaves Weak Concurrentism looking attractive. However, Weak Concurrentism might also be thought to have some implausible consequences of its own. Nonetheless, I (...) argue that, on closer inspection, these consequences are not implausible at all – at least by the lights of the Desire Satisfactionist. I do not offer a full-blown defence of Weak Concurrentism, but rather aim to defend only a conditional conclusion: in so far as one is committed to Actual Desire Satisfactionism, Weak Concurrentism represents the best way to tackle the problems raised by the temporal nature of desires.
