perhaps, when after having reported all their opinions, I am asked for my own, I shall impugn none of my predecessors’ decisions, and shall say, “I will also add somewhat to them.” Meanwhile I follow nature, which is a point upon which every one of the Stoic philosophers are agreed: true wisdom consists in not departing from nature and in moulding our conduct according to her laws and model. A happy life, therefore, is one which is in accordance with its own nature, and cannot be brought about unless in the first place the mind be sound and remain so without interruption, and next, be bold and vigorous, enduring all things with most admirable courage, suited to the times in which it lives, careful of the body and its appurtenances, yet not troublesomely careful. It must also set due value upon all the things which adorn our lives, without overestimating any one of them, and must be able to enjoy the bounty of Fortune without becoming her slave. You understand without my mentioning it that an unbroken calm and freedom ensue, when we have driven away all those things which either excite us or alarm us: for in the place of sensual pleasures and those slight perishable matters which are connected with the basest crimes, we thus gain an immense, unchangeable, equable joy, together with peace, calmness and greatness of mind, and kindliness: for all savageness is a sign of weakness.
