Abstract

Memory is, therefore, neither perception nor conception, but a state or affection of one of these, conditioned by lapse of time. As already observed, there is no such thing as memory of the present while present; for the present is object only of perception, and the future, of expectation, but the object of memory is the past. All memory, therefore, implies a time elapsed; consequently only those animals which perceive time remember, and the organ whereby they perceive time is also that whereby they remember. (Aristotle, OM, 449b24–30)
