"There are a good many people of the same kind as Harry. Many artists are of his kind. These persons all have two souls, two beings within them. There is God and the devil in them; the mother's blood and the father's; the capacity for happiness and the capacity for suffering; and in just such a state of enmity and entanglement toward and within each other as were the wolf and man in Harry. And these men, for whom life has no repose, live at times in their rare moments of happiness with such strength and indescribable beauty, the spray of their moment's happiness is flung so high and dazzlingly over the wide sea of suffering, that the light of it, spreading its radiance, touches others, too, with its enchantment. Thus, like a precious, fleeting foam over the sea of suffering arise all works of art, in which a single individual lifts himself for an hour or so high above his personal destiny that his happiness shines like a star and appears to all who see it as something eternal and as a happiness of their own. All these men, whatever their deeds and works may be, have really no life; that is to say, their lives are not their own and have no form. They are not heroes, artists, or thinkers in the same way that other men are judges, doctors, shoemakers or schoolmasters. Their life consists of a perpetual tide, unhappy and torn with pain, terrible and meaningless, unless one is ready to see its meaning in just those rare experiences, acts, thoughts and works that shine out above the chaos of such a life. To such men the desperate and horrible thought has come that perhaps the whole of human life is but a bad joke, a violent and ill-fated abortion of the primal mother, a savage and dismal catastrophe of nature. To them, too, however, the other thought has come that man is perhaps not merely a half-rational animal but a child of the gods and destined to immortality."
Herman Hesse, Steppenwolf
Perhaps a bit melancholy, but I think there is some truth in this.
