has a cause, but the force of nature itself none, so every particular act of will has a motive, but the will in general has none: indeed at bottom these two are one and the same. The will, as that which is metaphysical, is everywhere the boundary‐stone of every investigation, beyond which it cannot go. From the original and unconditioned nature of the will, which has been proved, it is explicable that man loves beyond everything else an existence full of misery, trouble, pain, and anxiety, and, again, full of ennui, which, if he considered and weighed it purely objectively, he would certainly abhor, and fears above all things the end of it, which is yet for him the one thing certain.(8) Accordingly we often see a miserable figure, deformed and shrunk with age, want, and disease, implore our help from the bottom of his heart for the prolongation of an existence, the end of which would necessarily appear altogether desirable if it were an objective judgment that determined here. Thus instead of this it is the blind will, appearing as the tendency to life, the love of life, and the sense of life; it is the same which makes the plants grow. This sense of life may be compared to a rope which is stretched above the puppet‐show of the world of men, and on which the puppets hang by invisible threads, while apparently they are supported only by the ground beneath them (the objective value of life). But if the rope becomes weak the puppet sinks; if it breaks the puppet must fall, for the ground beneath it only seemed to support it: _i.e._, the weakening of that love of life shows itself as hypochondria, spleen, melancholy: its entire exhaustion as the inclination to suicide, which now takes place on the slightest occasion, nay, for a merely imaginary reason, for now, as it were, the man seeks a quarrel with himself, in order to shoot himself dead, as many do with others for a like purpose;—indeed, upon necessity, suicide is resorted to without any special occasion. (Evidence of this will be found in Esquirol, _Des maladies mentales_, 1838.) And as with the persistence in life, so is it also with its action and movement. This is not something freely chosen; but while every one would really gladly rest, want and ennui are the whips that keep the top spinning. Therefore the whole and every individual bears the stamp of a forced condition; and every one, in that, inwardly weary, he longs for rest, but yet must press forward, is like his planet, which does not fall into the sun only because a force driving it forward prevents it. Therefore everything is in continual strain and forced movement, and the course of the world goes on, to use an expression of Aristotle’s (_De cœlo_, ii. 13), “ου φυσει, αλλα βιᾳ” (_Motu, non naturali sed violento_). Men are only apparently drawn from in front; really they are pushed from behind; it is not life that tempts them on, but necessity that drives them forward. The law of motivation is, like all causality,
