We are therefore left with the Deflationary conception of action, which is well supported by the text. There are, Locke says, “but two sorts of Action, whereof we have any Idea, viz. Thinking and Motion” (E1–5 II.xxi.4: 235—see also E1–5 II.xxi.8: 237 and E4–5 II.xxi.72: 285); “Thinking, and Motion…are the two Ideas which comprehend in them all Action” (E1–5 II.xxii.10: 293). It may be that, in the sense in which “action” is opposed to “passion”, some corporeal motions and mental operations, being produced by external causes rather than self-initiated, are not actions. But that is not the sense in which all motions and thoughts are “called and counted Actions” in Locke’s theory of action (E4–5 II.xxi.72: 285). As seems clear, convulsive motions are actions inasmuch as they are motions, and thoughts that occur in the mind unbidden are actions inasmuch as they are mental operations.
