 There are obvious similarities between imagination and memory: both typically involve imagery, both typically concern what is not presently the case, and both frequently involve perspectival representations. Thomas Hobbes (Leviathan: 2.3) claims that “imagination and memory are but one thing, which for diverse consideration has diverse names”. In making this bold statement, Hobbes represents an extreme version of continuism, a view on which imagination and memory refer to the same psychological mechanisms.
