The genital organs are, far more than any other external member of the body, subject merely to the will, and not at all to knowledge. Indeed, the will shows itself here almost as independent of knowledge, as in those parts which, acting merely in consequence of stimuli, are subservient to vegetative life and reproduction, in which the will works blindly as in unconscious nature. For generation is only reproduction passing over to a new individual, as it were reproduction at the second power, as death is only excretion at the second power. According to all this, the genitals are properly the _focus_ of will, and consequently the opposite pole of the brain, the representative of knowledge, _i.e._, the other side of the world, the world as idea. The former are the life-sustaining principle ensuring endless life to time. In this respect they were worshipped by the Greeks in the _phallus_, and by the Hindus in the _lingam_, which are thus the symbol of the assertion of the will. Knowledge, on the other hand, affords the possibility of the suppression of willing, of salvation through freedom, of conquest and annihilation of the world. We already considered fully at the beginning of this Fourth Book how the will to live in its assertion must regard its relation to death. We saw that death does not trouble it, because it exists as something included in life itself and belonging to it. Its opposite, generation, completely counterbalances it; and, in spite of the death of the individual, ensures and guarantees life to the will to live through all time. To express this the Hindus made the _lingam_ an attribute of Siva, the god of death. We also fully explained there how he who with full consciousness occupies the standpoint of the decided assertion of life awaits death without fear. We shall therefore say nothing more about this here. Without clear consciousness most men occupy this standpoint and continually assert life. The world exists as the mirror of this assertion, with innumerable individuals in infinite time and space, in infinite suffering, between generation and death without end. Yet from no side is a complaint to be further raised about this; for the will conducts the great tragedy and comedy at its own expense, and is also its own spectator. The world is just what it is because the will, whose manifestation it is, is what it is, because it so wills. The justification of suffering is, that in this phenomenon also the will asserts itself; and this assertion is justified and balanced by the fact that the will bears the suffering. Here we get a glimpse of _eternal justice_ in the whole: we shall recognise it later more definitely and distinctly, and also in the particular. But first we must consider temporal or human justice.(73)
