According to ecological psychology, animals perceive not just the qualities of things in their environment, but their affordances: in James Gibson’s words, ’what things furnish, for good or ill’. I propose a metaphysics for affordances that fits into a contemporary anti-Humean metaphysics of powers or potentialities. The goal is to connect two debates, one in the philosophy of perception and one in metaphysics, that stand to gain much from each other.

In this introductory study I discuss the notion of alternative possibilities and its relation to contemporary debates on free will and moral responsibility. I focus on two issues: whether Frankfurt-style cases refute the principle of alternative possibilities, and whether alternative possibilities are relevant to grounding free will and moral responsibility. With respect to the first issue, I consider three objections to Frankfurt-syle cases: the flicker strategy, the dilemma defense, and the objection from new dispositionalism. With respect to the second issue, (...) I consider the debate between Alternative Possibilities views and Actual Sequence views, as framed by Carolina Sartorio in her Causation and Free Will. I then explain how these two issues are relevant to the papers included in this volume. (shrink)

According to all varieties of virtue reliabilism knowledge is always gained through the exercise of epistemic competences. These competences can be conceived as competences to form true beliefs, or as competences to know. I will present a short but decisive argument against the idea that knowledge is always gained through the exercise of competences to know. The competence to know isn’t necessary for gaining knowledge.

Frankfurt examples invite controversy over whether the pertinent agent in these examples lacks the specific ability to do otherwise, and whether what she does can be obligatory or permissible. We develop an account of ability that implies that this agent does not have the specific ability to refrain from performing the germane action. The account also undergirds a view of obligation that entails that it is morally required or prohibited for an agent to perform an action only if she has (...) the specific ability to do, and to do otherwise than, perform it. Therefore, in Frankfurt examples, it is neither obligatory nor impermissible for the relevant agent to do what she does. (shrink)
