Meanwhile it surprises one to find, both in the world of human beings and in that of animals, that this great, manifold, and restless motion is sustained and kept going by the medium of two simple impulses--hunger and the instinct of sex, helped perhaps a little by boredom--and that these have the power to form the _primum mobile_ of so complex a machinery, setting in motion the variegated show! Looking at the matter a little closer, we see at the very outset that the existence of inorganic matter is being constantly attacked by chemical forces which eventually annihilates it. While organic existence is only made possible by continual change of matter, to keep up a perpetual supply of which it must consequently have help from without. Therefore organic life is like balancing a pole on one's hand; it must be kept in continual motion, and have a constant supply of matter of which it is continually and endlessly in need. Nevertheless it is only by means of this organic life that consciousness is possible. Accordingly this is a _finite existence_, and its antithesis would be an _infinite_, neither exposed to any attack from without nor in want of help from without, and hence ἀεί ὡσαύτως ὄν, in eternal rest; οὔτε γιγνόμενον, οὔτε ἀπολλύμενον, without change, without time, and without diversity; the negative knowledge of which is the fundamental note of Plato's philosophy. The denial of the will to live reveals the way to such a state as this. * * * * * The scenes of our life are like pictures in rough mosaic, which have no effect at close quarters, but must be looked at from a distance in order to discern their beauty. So that to obtain something we have desired is to find out that it is worthless; we are always living in expectation of better things, while, at the same time, we often repent and long for things that belong to the past. We accept the present as something that is only temporary, and regard it only as a means to accomplish our aim. So that most people will find if they look back when their life is at an end, that they have lived their lifelong _ad interim_, and they will be surprised to find that something they allowed to pass by unnoticed and unenjoyed was just their life--that is to say, it was the very thing in the expectation of which they lived. And so it may be said of man in general that, befooled by hope, he dances into the arms of death. Then again, there is the insatiability of each individual will; every time it is satisfied a new wish is engendered, and there is no end to its eternally insatiable desires.
