This paper advances a reductive semantics for ‘ought’ and a naturalistic theory of normativity. It gives a unified analysis of predictive, instrumental, and categorical uses of ‘ought’: the predictive ‘ought’ is basic, and is interpreted in terms of probability. Instrumental ‘oughts’ are analyzed as predictive ‘oughts’ occurring under an ‘in order that’ modifer (the end-relational theory). The theory is then extended to categorical uses of ‘ought’: it is argued that they are special rhetorical uses of the instrumental ‘ought’. Plausible conversational principles explain how this end-relational ‘ought’ can perform the expressive functions of the moral ‘ought’. The notion of an ‘ought-simpliciter’ is also discussed.

In this paper, I distinguish between two varieties of actualism—hardcore actualism and softcore actualism—and I critically discuss Ross Cameron’s recent arguments for preferring a softcore actualist account of the truthmakers for modal truths over hardcore actualist ones. In the process, I offer some arguments for preferring the hardcore actualist account of modal truthmakers over the softcore actualist one.

Actualism is the doctrine that the only things there are, that have being in any sense, are the things that actually exist. In particular, actualism eschews possibilism, the doctrine that there are merely possible objects. It is widely held that one cannot both be an actualist and at the same time take possible world semantics seriously — that is, take it as the basis for a genuine theory of truth for modal languages, or look to it for insight into the modal structure of reality. For possible world semantics, it is supposed, commits one to possibilism. In this paper I take issue with this view. To the contrary, I argue that one can take possible world semantics seriously and yet remain in full compliance with actualist scruples.

In this paper I look at three challenges to the very possibility of an ethics of belief and then show how they can be met. The first challenge, from Thomas Kelly, says that epistemic rationality is not (merely) a form of instrumental rationality. If this claim is true, then it will be difficult to develop an ethics of belief that does not run afoul of naturalism. The second challenge is the Non-Voluntarism Argument, which holds that because we cannot believe at will and because ought implies can, there can be no ethics of belief. The third challenge comes from Richard Feldman, who claims that there is no such thing as ought all-things-considered. He says, for example, that moral oughts can be weighed against other moral oughts and that epistemic oughts can be compared to each other, but that there is no way to weigh moral oughts against epistemic oughts. If this is true, then norms about what one ought to believe are not nearly as important as one might have hoped or as philosophers have traditionally thought. In answering these three challenges, I try to show how and why the project of developing epistemic norms might be a promising avenue of research, despite claims to the contrary.

i. Using biological theory to discover facts about humans (and about the biological world in general) that, in conjunction with oughts (normative principles) we already accept can be used to derive other oughts.

"Subjective oughts": but force of the ought is relative to some of your antecedent beliefs/ intentions, not to you. (Different states might push you in incompatible directions.).
