This insupportable companion of inaction is usually banished by work; but then, to him who is obliged to labor, is not work often distasteful, and even a species of misfortune? Indeed, there are few, if any, who ever work save under compulsion; and whether the compulsion is caused by the attracting force of fame, the desire to escape from want, or comes simply as a promise of relief from boredom, the incentive and necessity are one and the same. It is true that man when at work is consoled by the thought of rest, but then work and rest merely serve to change his position, and they do so very much in the same manner as that uneasiness which forces the invalid to turn in bed, and then to turn back again, when it has shown him that the second position is no better than the first. The great blessings of life, therefore, reduce themselves, in brief, to this: they represent but that affranchisement from pain which is equivalent to a state of pure indifference; but as no one reaches this condition save momentarily and by accident, it seems to follow that life has less charm than non-existence, which represents indifference in its most absolute and unquestioned form. This state of beatitude is yet to be acquired; meanwhile, as Schiller says, so long as philosophy does not govern the world, hunger and love will suffice to keep it in motion. After the four causes of contentment, Hartmann's views on the two incentives to activity remain to be examined. In regard to the first, it may be said without extravagance that the sufferings of hunger rule the greater portion of the 1300 millions of the earth's inhabitants. Europe not long since averaged a famine every seven years; now, the facilities of communication have replaced famine with an increased valuation of food. Death is the rarest and the least important evil that hunger occasions; what is most to be regarded is the physical and intellectual impoverishment, the mortality among children, and the particular maladies which it engenders. According to Hartmann, the analysis of hunger shows that in satisfying its demands the individual does not raise his sensibility above a state of pure indifference. He may, it is true, under favorable circumstances, cause a certain pleasure to predominate over suffering by means of taste and digestion; but in the animal kingdom, as in humanity, taken as a whole, the tortures caused by hunger are greatly in excess of any pleasures that may attach to it. In fact, from Hartmann's standpoint, the necessity of eating is in itself a misfortune.
