"The measure of his possible happiness is determined beforehand by his individuality. In particular, the limits of his mental powers have fixed once for all his capacity for pleasures of a higher order. If those powers are small, all the efforts from without, everything done for him by mankind or good fortune, will not enable him to rise above the ordinary half-animal human happiness and comfort. He is left to depend on the pleasures of the senses, on a cosy and cheerful family life, on low company and vulgar pastimes. Even education, on the whole, cannot do very much, if anything, to broaden his horizon. For the highest, most varied, and most permanent pleasures depend mainly on intimate mental powers. Therefore it is clear from this how much our happiness depends on what we are, our individuality, whereas in most cases we take into account only our fate, only what we have or represent. Fate, however, can improve; moreover, if we are inwardly wealthy we shall not demand much from it. On the other hand, a fool remains a fool, a dull blockhead a dull blockhead, till the end of his life, even if he were surrounded by houris in paradise."
