Coming finally to the Ethics of the Stoic philosophy, we find for the chief end of life this definition, 'A life consistent with itself,' or, as it was otherwise expressed, 'A life consistent with Nature.' The two definitions are really identical; for the law of nature is the law of our nature, and the reason in our being the reason which also is in God, the supreme Ruler of the universe. This is substantially in accordance with the celebrated law of right action laid down by Kant, "Act so that the maxim of thine action be capable of being made a law of universal action." Whether a man act thus or no, by evil if not by good the eternal law will satisfy itself; the question is of import only for the man's own happiness. Let his will accord with the universal will, then the law will be fulfilled, and the man will be happy. Let his will resist the universal will, then the law will be fulfilled, but the man will bear the penalty. This was expressed by Cleanthes in a hymn which ran somewhat thus-- Lead me, O Zeus most great, And thou, Eternal Fate: What way soe'er thy will doth bid me travel That way I'll follow without fret or cavil. {237} Or if I evil be And spurn thy high decree, Even so I still shall follow, soon or late. Thus in the will alone consists the difference of good or ill for us; in either case Nature's great law fulfils itself infallibly. To their view on this point we may apply the words of Hamlet: "If it be now, 'tis not to come; if it be not to come, it will be now; if it be not now, yet it will come; the _readiness_ is all."
