What I want to do in this essay is examine a notorious argument put forward by Galen Strawson. He advocates what he describes as an a priori argument against the possibility of ultimate (moral) responsibility. There have been many attempts at answering Strawson, but whether they have been successful is debatable. I attempt to employ Henri Bergson's approach to the free will debate and assess whether what he says has any purchase in terms of criticism of Strawson's position. I conclude (...) that Bergson's views offer a serious alternative in debates about free will. (shrink)
