In E2–5, Locke explicitly gives up this conception of the will and willing, explaining why he does so, making corresponding changes in the text of the Essay, even while leaving passages that continue to suggest the desiderative conception. He writes: “[T]hough a Man would preferr flying to walking, yet who can say he ever wills it?” (E2–5 II.xxi.15: 241). The thought here is that, as Locke (rightly) recognizes, my being more pleased with flying than walking does not consist in (or even entail) my willing to fly. This is in large part because it is necessarily implied in willing motion of a certain sort that one exert dominion that one takes oneself to have (E2–5 II.xxi.15: 241), that “the mind [endeavor] to give rise…to [the motion], which it takes to be in its power” (E2–5 II.xxi.30: 250). So if I do not believe that it is in my power to fly, then it is impossible for me to will the motion of flying, even though I might be more pleased with flying than I am with any alternative. Locke concludes (with the understatement) that “Preferring which seems perhaps best to express the Act of Volition, does it not precisely” (E2–5 II.xxi.15: 240–241).
