Abstract

The principle “Ought implies can” has important connections with the problem of free will. In this chapter, I lay out these connections and proceed to consider a recent exercise in “experimental philosophy” whose results some have regarded as constituting an important challenge to the principle. Although many, perhaps most, philosophers regard the principle as an analytic truth, a survey of non-philosophers conducted in 2016 has led its authors to conclude that non-philosophers do not accept the “Ought implies can” principle. The main topics of this chapter are a critical evaluation of the authors’ interpretation of the results of their survey and an examination of the implications of those results for the question whether the principle is true.
