We argue that the way in which the concept of expertise is understood and invoked has prevented progress in the debate as to whether moral philosophers can be said to be ‘moral experts’. We offer an account of expertise that draws on the role of tacit knowledge in order to provide a basis upon which the debate can progress. Our analysis consists of three parts. In the first part we highlight two specific problems in the way that the concept of expertise has been invoked in the moral expertise debate, namely the understanding of expertise as an exclusive concept and the conflation of expertise with the idea of ‘authority’. In the second part we suggest an alternative way of approaching the concept of expertise. This is based on Collins and Evans’ sociological theory of expertises. This theory provides a valuable analytical framework for thinking about claims to expertise and for drawing the kinds of distinctions which allow for different kinds of moral expertises and competencies. In the final part, we show how the application of this theory helps to avoid some of the problematic conclusions which theorists have arrived at to date and provides a common platform for debate. Ultimately, it permits the argument to be made that moral philosophers could be considered specialist members of an expert community of moral decision-makers.

Many materialist ontologies characterize the existence of everyday, middle-sized objects as reducible to collections or mereological sums of smaller, more fundamental particle constituents. Baker would have it otherwise and has set out a defence of her Constitution View of ontology that takes everyday objects to be irreducibly real and of a vast array of kinds.Motivating an interest in the metaphysics of everyday objects is not obviously straightforward when contemporary metaphysics is filled with attempts to answer seemingly more challenging questions about the existence of disputed classes of objects, such as abstracta, or very specific, unusual phenomena such as holes, rather than the mundane case of these middle-sized concreta. Yet this is Baker's point: that many kinds of ordinary objects have been overlooked by philosophers to the point where we lack an adequate account of their significance in our practices and attitudes. Moreover, in a climate of metaphysics often governed by those of a strong eliminitivist inclination with a preference for Quinean desert landscapes, the advocating of an almost indulgent ontological pluralism is enough to make this book worth reading.Those familiar with Baker's work will not be surprised that this approach to ontology is grounded from her perspective of ‘Practical Realism’. This view – partly a legacy of Aristotle, partly of G. E. …

Parfit’s (1984) Non-Identity Problem provides a strong line of argument that we cannot be harmed by pre-conception choices or actions. I argue that we can no longer appeal to the Non-Identity problem in order to justify using pre-conception genetic screening and selection techniques as a harmless tool to determine the genetic constitution of future individuals. My criticism of the Non-Identity problem is based on a rejection of the metaphysical foundations of Parfit’s argument - Kripke’s (1980) essentialist arguments for the necessity of origin. I offer an alternative account of modal harms based on counterpart theory such as that offered by David Lewis (1986). On this account, individuals can make legitimate harm claims in regard to pre-conception choices made in determining their genetic constitution by appeal to their counterparts across possible worlds.
