  So, in E1, the will is the mind’s power to be more pleased with the consideration of an idea than with the not considering it, or to be more pleased with the motion of a part of one’s body than with its remaining at rest. When we lack something that would deliver more pleasure than we currently experience, we become uneasy at its absence. And this kind of uneasiness (or pain: E1–5 II.vii.1: 128), is what Locke describes as desire (E1–5 II.xx.6: 230; E2–5 II.xxi.31–32: 251) (though also as “joined with”, “scarce distinguishable from”, and a “cause” of desire—see Section 8 below). So, in E1, the will is the mind’s power to desire or want the consideration of an idea more than the not considering it, or to desire or want the motion of a part of one’s body more than its remaining at rest. (At E2–5 II.xxi.5: 236, Locke adds “and vice versâ”, to clarify that it can also happen, even according to the E1 account, that one prefers not considering an idea to considering it, or not moving to moving.)[1]
