" Epicurus, on the other hand, says something very different, ‘Man is not by nature adapted for living in civic communities.’98 Nothing, he adds, is an end in itself except individual happiness. Justice, taxes, voting – these have no value in themselves, other than their utilitarian value for what happiness they bring the individual. Independence is everything. In the same way, the Stoics, after Zeno, sought apathia, passionlessness – their ideal was to be impassive, dry, detached and invulnerable. ‘Man is a dog tied to a cart; if he is wise he will run with it.’99 "
