 Hence another way of putting the contrast between sense and memory, on the one hand, and imagination, on the other, is to say that the former present ideas according to “real bonds of union” whereas the latter presents ideas according to laws of association (Gerard 1759, 167). In this way association becomes an essential element of imagination. Indeed on Gerard’s view there seems, unofficially at least, to be no real difference between association and imagination—at most imagination is the locus of association.
