 Austin considers this issue in his “Ifs and Cans” (1956a). There, he discusses and rejects attempts in G.E. Moore 1912 and Nowell-Smith 1954 to provide accounts of what we can do on which it being true that we can do things (/refrain from doing them) is compatible with its being determined by our circumstances that we don’t in fact do them (/refrain from doing them). Austin thinks that his objections to the accounts on which he focuses provide partial support to the view that our ordinary claims about what we can do are incompatible with determinism.
