 A more common anxiety turns on ‘causal deviance’ (Davidson 1973, p. 79). If we are trying to say what it is to act intentionally, the condition of doing A because one so intends looks insufficient. For it says nothing about the causal path from intention to action. If I intend to be shaking in order to signal my confederate, and this intention makes me nervous, so that I shake, I am shaking because I so intend—though not intentionally. My intention did not cause me to shake ‘in the right way.’ Nor is the ‘right way’ obviously a matter of ‘proximate’ causation or the absence of causal intermediaries, since a causal theorist may well allow for neural intermediaries, and further intentions, in the causal path from intention to action. There is a failure of intentional action only when the intermediaries are of the wrong kind.
