In keeping with this conception of the will as desire, Locke in E1 then defines an exercise of the will, which he calls “willing” or “volition”, as an “actual preferring” of one thing to another (E1 II.xxi.5: 236). For example, I have the power to prefer the upward motion of my arm to its remaining at rest by my side. This power, in E1, is one aspect of my will. When I exercise this power, I actually prefer the upward motion of my arm to its remaining at rest, i.e., I am more pleased with my arm’s upward motion than I am with its continuing to rest. This is what Locke, in E1, thinks of as my willing the upward motion of my arm (or, as he sometimes puts it, my willing or volition to move my arm upward).
