It is usually assumed that what Lewis says about the given in Mind and the World-Order (MWO) and An Analysis of Knowledge and Valuation (AKV) is essentially the same, and that both works are defenses of foundationalism. However, this assumption faces two problems: first, it is difficult to bring Lewis's diverse remarks on the given into coherence, especially when those in MWO are compared with those in AKV; and second, though AKV is a defense of foundationalism, there is much in (...) MWO that can be read as a critique of foundationalism. In this paper a different reading of Lewis is proposed, one that avoids these problems. This is developed by going farther back in Lewis, to his Harvard Ph.D. dissertation, The Place of Intuition in Knowledge (PIK). By tracing Lewis's discussion of the given from PIK through MWO up to AKV, it is shown that the phrase 'the given' is used to refer to two different doctrines, and that Lewis's position on foundationalism undergoes a fundamental change, roughly, from indifference to rejection to acceptance.
