 The view that Locke argues for the distinction of P/SQs, at least in part, from the truth or adequacy of the CT (held by Alexander 1985: 111–30; Mackie 1976: 17–8) is met with two objections: Locke’s main interest in Essay Book 2 is in ideas (Atherton 1992) and Locke endorses neither the truth nor adequacy of CT (Ayers 2011: 136–7; Downing 1998; McCann 2011: 179–85).
