‘Ought’ implies ‘can’ and the principle of alternate possibilities
نویسنده
چکیده
In his paper ‘What we are morally responsible for’,1 Harry Frankfurt claims, in passing, that while the ‘Frankfurt Counterexamples’2 are counterexamples to the Principle of Alternate Possibilities (PAP: An agent is morally blameworthy3 for what she has done only if she could have done otherwise), they are not counterexamples to the famous Kantian maxim that ‘Ought’ implies ‘Can’. In an Analysis paper of a few years ago, David Widerker objected to Frankfurt’s claim by arguing that the ‘Ought’ implies ‘Can’ maxim (The Maxim: If an agent is morally obligated to act in a particular way, then the agent has the ability to act in that way) entails PAP; hence, counterexamples to PAP are counterexamples to the Maxim as well.4 Widerker’s argument points to a serious problem for those who believe that PAP is to be rejected for roughly the reasons that Frankfurt suggests, even though the Maxim is to be maintained. Such a position might be important for what John Fischer has termed ‘actual sequence’ views of freedom:5 views that see the status of an action as free or unfree as depend-

One popular line of argument put forward in support of the principle that the right is prior to the good is to show that teleological theories, which put the good prior to the right, lead to implausible normative results. There are situations, it is argued, in which putting the good prior to the right entails that we ought to do things that cannot be right for us to do. Consequently, goodness c...
متن کاملFree Will and Moral Responsibility in Islamic Philosophy
According to a common view among Muslim philosophers, a moral agent has free will if and only if she is able to do an action when she wants to and is able to avoid it when she wants otherwise. Implicit in this view is the Principle of Alternative Possibilities (PAP). On the other hand, according to this view, free will is dependent on requirements such as conception, judgement, tendency, decisi...
