Note 13 — Chapter II

In my previous work I devoted a chapter to “Imagination,” in which I treated of the psychology of ideation so far as animals are concerned. It is now needful to consider ideation with reference to man; and, in order to do this, it is further needful to revert in some measure to the ideation of animals. I will, however, try as far as possible to avoid repeating myself, and therefore in the three following chapters I will assume that the reader is already acquainted with my previous work. Indeed, the argument running through the three following chapters cannot be fully appreciated unless their perusal is preceded by that of chapters ix. and x. of Mental Evolution in Animals.
