  In this way, Strawson hoped to capture what he took to be the central core of Kant’s position, but without appeal to the ‘doctrines of transcendental psychology’ (Strawson 1966: 97), which he found to be problematic. Likewise, in Individuals, Strawson presented an argument starting from the premise that we think of the world as containing objective particulars in a single spatiotemporal system, to the conclusion that objects continue to exist unperceived, where the latter is said to required in order to make possible the kind of identification and re-identification necessary for the former (cf. Strawson 1959: 31–58). Thus, as Strawson famously put it, the skeptic ‘pretends to accept a conceptual scheme’ of a world containing objects in a spatio-temporal system, ‘but at the same time quietly rejects one of the conditions of its employment’ (Strawson 1959: 35).
