Argues for an interpretation of Iris Murdoch on which her account of moral reasons has Platonic roots, and on which she gives an ontological proof of the reality of the Good. This reading explains the structure of Sovereignty, how Murdoch's claims differ from a focus on "thick moral concepts," and how to find coherent arguments in her book.

Aristotle believes that certain pursuits are objectively choice worthy regardless of our attitudes towards them. Moreover, in order to have the correct beliefs about which actions are choice worthy, they must have acquired the right dispositions during their upbringing. Bernard Williams argues that Aristotle’s theory of moral education undermines belief in objective values. In response to Williams, Julia Annas argues that Aristotle does not ground ethics in the external point of view, but rather in the desires and commitments that people (...) already have. In this thesis, I argue that Aristotle held the view to which Williams objects and that Williams’ objection fails. Aristotle’s appeals to nature shows that he does not ground values in individual desires and commitments. Moreover, moral education does not alone undermine our confidence in the truth of our commitments. (shrink)

When someone does something for a reason, what are the reasons for which she does what she does? What is her ‘motivating reason’, as it is sometimes put? The simple answer is: it depends on what is meant by ‘motivating reason’. Non-Psychologists hold that motivating reasons are what the agent believes. I have shown that given that we understand ‘motivating reasons’ as what I term 'grounds', this is quite correct, as what we believe is what plays the role of a (...) ground. However, we have to be careful not to confuse the role of a ground and the role of an explanans. For the conflation of those two roles can occlude the truth in Non-Psychologism. What the Non-Psychologist about Grounds should say is that what plays the role of an explanans, when someone acts on a ground, is a motivation-fact. She should also say that there are two kinds of motivation-facts: those that include normative reasons and those that do not. (shrink)
