Isaiah Berlin wrote of one of his intellectual heroes, John Stuart Mill, that "what he came to value most was neither rationality nor contentment, but diversity, versatility, fullness of life - the unaccountable leap of individual genius, the spontaneity and uniqueness of a man, a group, a civilisation. What he hated and feared was narrowness, uniformity, the crippling effect of persecution, the crushing of individuals by the weight of authority or of custom or of public opinion." It was that "fullness of life" that Berlin prized, which so well embodies my own view toward life.
