Two common theses in contemporary epistemology are that ‘knowledge excludes luck’ and that knowledge depends on ‘purely epistemic’ factors. In this essay, I shall argue as follows: given some plausible assumptions, ‘anti-luck epistemology,’ which is committed to the fi rst thesis, implies the falsity of the second thesis. That is, I will argue that anti-luck epistemology leads to what has been called ‘pragmatic encroachment’ on knowledge. Anti-luck epistemologists hoping to resist encroachment must accept a controversial thesis about true belief or a dubious claim about luck and value and interests.

Many believe that we are not morally responsible for what we cannot help doing. Call this ‘the Traditional View of Responsible Agency.’ Some forty years ago, Harry Frankfurt (1969) challenged this view, thereby initiating a new stage of the free-will debate. In contrast to the previous stage, in which debate centered on how best to accommodate the Traditional View, contemporary theorists have focused on whether this view should be accepted at all. If the link between moral responsibility and avoidability is severed, an important threat to compatibilism is neutralized.

In the wake of Frankfurt's challenge, a tremendous literature has sprung up, with many ingenious responses matched by equally thoughtful extensions of Frankfurt's original argument. Quite recently, an altogether new line of response has been proposed. This new approach, versions of which have been advanced by Maria Alvarez (2009) and Helen Steward (2009), attempts to support the Traditional View indirectly, by appealing to the conditions for action, rather than to the conditions for moral responsibility per se.

The famous Cartesian Nicolas Malebranche (1638-1715) espoused the occasionalist doctrine that ‘there is only one true cause because there is only one true God; that the nature or power of each thing is nothing but the will of God; that all natural causes are not true causes but only occasional causes’ (LO, 448, original italics). One of Malebranche's well-known arguments for occasionalism, known as, the ‘no necessary connection’ argument (or, NNC) stems from the principle that ‘a true cause… is one such that the mind perceives a necessary connection between it and its effect’ (LO, 450).
