exhibits this as two fundamentally different things is not unconditioned, but relative, a knowledge of the phenomenon, not of the thing in itself. In the morning the fly exists again; it also exists again in the spring. What distinguishes for it the winter from the night? In Burdach’s “Physiology,” vol. i. § 275, we read, “Till ten o’clock in the morning no _Cercaria ephemera_ (one of the infusoria) is to be seen (in the infusion), and at twelve the whole water swarms with them. In the evening they die, and the next morning they again appear anew.” So it was observed by Nitzsch six days running. So everything lingers but a moment, and hastens on to death. The plant and the insect die at the end of the summer, the brute and the man after a few years: death reaps unweariedly. Yet notwithstanding this, nay, as if this were not so at all, everything is always there and in its place, just as if everything were imperishable. The plant always thrives and blooms, the insect hums, the brute and the man exist in unwasted youth, and the cherries that have already been enjoyed a thousand times we have again before us every summer. The nations also exist as immortal individuals, although sometimes their names change; even their action, what they do and suffer, is always the same; although history always pretends to relate something different: for it is like the kaleidoscope, which at every turn shows a new figure, while we really always have the same thing before our eyes. What then presses itself more irresistibly upon us than the thought that that arising and passing away does not concern the real nature of things, but this remains untouched by it, thus is imperishable, and therefore all and each that _wills_ to exist actually exists continuously and without end. Accordingly at every given point of time all species of animals, from the gnat to the elephant, exist together complete. They have already renewed themselves many thousand times, and withal have remained the same. They know nothing of others like them, who have lived before them, or will live after them; it is the species which always lives, and in the consciousness of the imperishable nature of the species and their identity with it the individuals cheerfully exist. The will to live manifests itself in an endless present, because this is the form of the life of the species, which, therefore, never grows old, but remains always young. Death is for it what sleep is for the individual, or what winking is for the eye, by the absence of which the Indian gods are known, if they appear in human form. As through the entrance of night the world vanishes, but yet does not for a moment cease to exist, so man and brute apparently pass away through death, and yet their true nature continues, just as undisturbed by it. Let us now think of that alternation of death and birth as infinitely rapid vibrations, and we have before us the enduring
