David Benatar has argued that the coming into existence of a sentient being is always a harm, and consequently that people who have children always do wrong. The most natural objection maintains that in many lives (at least) while there is some pain, there are also goods (including pleasures) that can outweigh the suffering. From Benatar’s perspective this move, while possibly useful in assessing the lives of those who actually exist, is not an effective defence of procreation. In the case of people who do not yet exist, he maintains that there is a crucial asymmetry arising from the putative fact that the absence of pain is good even if that good is not enjoyed by anyone, whereas absence of pleasure is not bad unless there is somebody for whom that absence is a deprivation. For the potentially existing, he concludes, preventing the pain of existence is justified, but not so facilitating enjoyment of its pleasures. I argue that the asymmetry is insufficiently motivated. I also sketch two additional lines of argument against the asymmetry. First, it may not include all relevant factors. Second, plausible duties to prevent pain require possible sufferers, but do not apply straightforwardly when extended to include preventing the sufferers themselves

A wave of recent work in metaphysics seeks to undermine the anti-reductionist, functionalist consensus of the past few decades in cognitive science and philosophy of mind. That consensus apparently legitimated a focus on what systems do, without necessarily and always requiring attention to the details of how systems are constituted. The new metaphysical challenge contends that many states and processes referred to by functionalist cognitive scientists are epiphenomenal. It further contends that the problem lies in functionalism itself, and that, to save the causal significance of mind, it is necessary to re-embrace reductionism. We argue that the prescribed return to reductionism would be disastrous for the cognitive and behavioral sciences, requiring the dismantling of most existing achievements and placing intolerable restrictions on further work. However, this argument fails to answer the metaphysical challenge on its own terms. We meet that challenge by going on to argue that the new metaphysical skepticism about functionalist cognitive science depends on reifying two distinct notions of causality (one primarily scientific, the other metaphysical), then equivocating between them. When the different notions of causality are properly distinguished, it is clear that functionalism is in no serious philosophical trouble, and that we need not choose between reducing minds or finding them causally impotent. The metaphysical challenge to functionalism relies, in particular, on a naïve and inaccurate conception of the practice of physics, and the relationship between physics and metaphysics. Key Words: explanation; functionalism; mental causation; metaphysics; reductionism

According to various theorists and empirical scholars of behavior and decision, including economists, utility theorists, behavioral ecologists, behavioral economists and researchers in the new field of neuroeconomics the value (typically understood as utility) of competing choices must be represented on a common scale in order for them to count as competing at all, and in order for orderly comparison to lead to actual choices. For some neuroeconomists this means that expected (cardinal) utilities are neurally represented by firing rates of cells in specific brain regions. In this paper some important statements of the ‘common currency’ argument are reviewed and critically examined. A rational reconstruction of the key argument is then subject to criticism informed by a variety of empirical and theoretical considerations. In a strong form it does not survive the criticism, and this fact points the way to a re-examination of the sense in which complex living systems, including people, are agents in any straightforward sense
