The Cyrenaics were
hedonists and held that pleasure was the supreme good in life, especially physical pleasure, which they thought more intense and more desirable than mental pleasures. Pleasure is the only good in life and pain is the only evil.
Socrates had held that
virtue was the only human good, but he had also accepted a limited role for its utilitarian side, allowing pleasure to be a secondary goal of moral action. Aristippus and his followers seized upon this, and made pleasure the sole final goal of life, denying that virtue had any intrinsic value.
Epistemology The Cyrenaics were known for their
skeptical theory of knowledge. They reduced logic to a basic doctrine concerning the
criterion of truth. They believed that we can know with certainty our immediate
sense-experiences (for instance, that I am having a sweet sensation now) but can know nothing about the nature of the objects that cause these sensations (for instance, that the honey is sweet). They also denied that we can have knowledge of what the experiences of other people are like. All knowledge is of one's own immediate sensation. These sensations are motions that are purely subjective, and are painful, indifferent, or pleasant, according as they are violent, tranquil, or gentle. Further, they are entirely individual, and can in no way be described as being of the world objectively. Feeling, therefore, is the only possible criterion of knowledge and of conduct. Our ways of being affected are alone knowable. Thus, the sole aim for everyone should be pleasure.
Ethics Cyrenaicism deduces a single, universal aim for all people which is pleasure. Furthermore, all feeling is momentary and homogeneous. It follows that past and future pleasure have no real existence for us, and that among present pleasures, there is no distinction of kind. Socrates had spoken of the higher pleasures of the intellect; the Cyrenaics denied the validity of this distinction and said that bodily pleasures, being more simple and more intense, were preferable. Momentary pleasure, preferably of a physical kind, is the only good for humans. When it comes to pain, the Cyrenaics held the opinion that pain that occurs suddenly is more difficult to endure than pain that can be foreseen. However, some actions that give immediate pleasure can create more than their equivalent of pain. The wise person should be in control of pleasures rather than be enslaved to them; otherwise, pain will result, and this ability requires judgement to evaluate the different pleasures of life. Regard should be paid to law and custom because even though these things have no intrinsic value on their own, violating them will lead to unpleasant penalties being imposed by others. Likewise, friendship and justice are useful because of the pleasure they provide. Thus, the Cyrenaics believed in the hedonistic value of social obligation and altruistic behavior. Like many of the leading modern
utilitarians, they combined with their psychological distrust of popular judgments of right and wrong, and their firm conviction that all such distinctions are based solely on law and convention. The equally unwavering principle that the wise person who would pursue pleasure logically must abstain from that which is usually thought wrong or unjust. This idea, which occupies a prominent position in systems like those of
Jeremy Bentham,
Volney, and even
William Paley, was clearly of prime importance to the Cyrenaics. ==Legacy==
