Let us imagine, then, with Hartmann, a man who is not a genius, but simply a man of ordinary culture, enjoying the advantages of an enviable position; a man who is neither wearied by pleasure nor oppressed by exceptional misfortunes; in brief, a man capable of comparing the advantages which he enjoys with the disadvantages of inferior members of society; let us suppose that Death comes to this man and speaks somewhat as follows: "Your hour is at hand; it remains with you, however, to live at once a new life, with the past entirely effaced, or to accept the grave as it is." There can be little doubt, if this hypothetical individual has not lived carelessly and thoughtlessly, and does not permit his judgment to be biased by the desire for life at any price, that he would choose death in preference to another existence, in which he would be assured of none of the favorable conditions which he had hitherto enjoyed. He will recommence his own life, perhaps, but no other of an inferior grade. This choice, however, would be that of an intelligent man, and might be objected to on a ground not dissimilar to the one already advanced against the judgments of genius. But let us follow Hartmann still further, and in descending the spiral of humanity put the same question to every one we meet; let us take, for instance, a woodcutter, a Hottentot, or an orang-outang, and ask of each which he prefers, death, or a new existence in the body of a hippopotamus or a flea. Each will answer, "death," but none of them will hesitate between their own lives and death; and if a like question be put to the hippopotamus and the flea, their answers will be precisely similar. The difference in the comparative judgment that each would bring to bear on his own life, and on that of life in an inferior degree, results evidently from the fact that on being questioned each enters imaginatively into the existence of the lower creation, and at once judges its condition to be insupportable. The difference between the opinion which the flea holds on the value of its own existence and our own private judgment on this insect is derived simply from the fact that the flea has a quantity of absurd illusions which we do not share, and these illusions cause it such an excess of imaginary happiness that in consequence it prefers its own life to death. In this the flea is not wrong; on the contrary, it is quite right, for the value of an existence can only be measured in accordance with its natural limitations. In this sense illusion is as serviceable as truth.
