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.
AristotleOf cases where a man is truthful both in speech and conduct when no considerations of honesty come in, from an habitual sincerity of disposition. Such sincerity may be esteemed a moral excellence; for the lover of truth, who is truthful even when nothing depends on it, will a fortiori be truthful when some interest is at stake, since having all along avoided falsehood for its own sake, he will assuredly avoid it when it is morally base; and this is a disposition that we praise.
