On stoic moral philosophy:

The virtuous life is free of all passions, which are intrinsically disturbing and harmful to the soul, but includes appropriate emotive responses conditioned by rational understanding and the fulfillment of all one's personal, social, professional, and civic responsibilities. The Stoics believed that the person who has achieved perfect consistency in the operation of his rational faculties, the "wise man," is extremely rare, yet serves as a prescriptive ideal for all. The Stoics believed that progress toward this noble goal is both possible and vitally urgent.
