In his views of life he partook of the character of the Stoic, the Epicurean, and the Cynic. In his personal character the Stoic predominated: his standard of morals was Epicurean, in so far as that it was utilitarian, taking as the sole test of right and wrong, the tendency of actions to produce pleasure or pain. But he had (and this was the Cynic element) scarcely any belief in pleasure: at least in his later years, of which alone on this subject I can speak confidently. He deemed very few pleasures worth the price which at all events in the present state of society, must be paid for them. The greatest miscarriages in life he considered attributable to the overvaluing of pleasures. Accordingly, temperance in the large sense intended by the Greek philosophers—stopping short at the point of moderation in all indulgences—was with him as with them, almost the cardinal point of moral precept.
