still weak and fragile, working to live, and yet not knowing why it does so, it will ask but one gift, the rest of an endless sleep that shall calm its weariness and immense ennui. It is then that humanity will have passed through the three periods of illusion, and in recognizing the nothingness of its former hopes will aspire only to absolute insensibility and the chaos of Nirvâna." It remains but to inquire what is to become of disillusionized humanity, and to what goal evolution is tending. The foregoing account of Hartmann's theory should have shown that this goal cannot be happiness, for at no period has it ever been reached, and, moreover, that with the progress of the world man is gaining a clearer perception of his misery. On the other hand, it would be illogical to suppose that evolution is to continue with no other aim than that of the discharge of the successive moments that compose it; for if each of these moments is valueless, evolution itself would be meaningless; but Hartmann, it may be remembered, has recognized in the Unconscious a principle of absolute wisdom, and the answer must be looked for elsewhere, but preferably in that direction which most noticeably points to some determined and progressive perfection. No such sign, however, is to be met with anywhere save in the development of consciousness; here progress has been clearly and uninterruptedly at work, from the appearance of the first globule to contemporaneous humanity, and in all probability will continue to advance so long as the world subsists. All things aid in its production and development, while to its assistance there come not only the perfecting of the nervous system, but also such personal incentives as the desire for wealth, which in increasing general welfare disfranchises the intellect; then, too, there are the stimulants to intellectual activity, vanity and ambition, and also sexual love, which heightens its aptitudes; in short, every instinct which is valuable to the species, and which costs the individual more pain than pleasure, is converted into an unalloyed and increasing gain for consciousness.
