It was assumed by the Greeks that the ways of nature were 'the ways of pleasantness,' and that 'all her paths' were 'peace.' This may seem to us a startling assumption, but that is because we do not mean by 'nature' the same thing as they did. We connect the term with the origin of a thing, they connected it rather with the end; by the 'natural state' we mean a state of savagery, they meant the highest civilization; we mean by a thing's nature what it is or has been, they meant what it ought to become under the most favourable conditions; not the sour crab, but the mellow glory of the Hesperides worthy to be guarded by a sleepless dragon, was to the Greeks the natural apple. Hence we find Aristotle maintaining that the State is a natural product, because it is evolved out of social relations which exist by nature. Nature indeed was a highly ambiguous term to the Greeks no less than to ourselves, but in the sense with which we are now concerned, the nature of anything was defined by the Peripatetics as 'the end of its becoming.' Another definition of theirs puts the matter still more clearly. 'What each thing is when its growth has been completed, that we declare to be the nature of each thing'. Following out this conception the Stoics identified a life in accordance with nature with a life in accordance with the highest perfection to which man could attain. Now, as man was essentially a rational animal, his work as man lay in living the rational life. And the perfection of reason was virtue. Hence the ways of nature were no other than the ways of virtue. And so it came about that the Stoic formula might be expressed in a number of different ways which yet all amounted to the same thing. The end was to live the virtuous life, or to live consistently, or to live in accordance with nature, or to live rationally. DIVISION OF PHILOSOPHY.
