Hedonism is a school of thought that argues that pleasure is the only intrinsic good. In very simple terms, a hedonist strives to maximize net pleasure (pleasure minus pain).
Ethical hedonism is the idea that all people have the right to do everything in their power to achieve the greatest amount of pleasure possible to them. It is also the idea that every person’s pleasure should far surpass their amount of pain. Ethical hedonism is said to have been started by a student of Socrates, Aristippus of Cyrene. He held the idea that pleasure is the highest good.
The Cyrenaic School
Aristippus of Cyrene
The Cyrenaics were an ultra-hedonist Greek school of philosophy founded in the 4th century BCE, supposedly by Aristippus of Cyrene, although many of the principles of the school are believed to have been formalized by his grandson of the same name, Aristippus the Younger. The school was so called after Cyrene, the birthplace of Aristippus. It was one of the earliest Socratic schools. The Cyrenaics taught that the only intrinsic good is pleasure, which meant not just the absence of pain, but positively enjoyable sensations. Of these, momentary pleasures, especially physical ones, are stronger than those of anticipation or memory. They did, however, recognize the value of social obligation, and that pleasure could be gained from altruism. Theodorus the Atheist was a latter exponent of hedonism who was a disciple of younger Aristippus, while becoming well known for espousing atheism. The school died out within a century, and was replaced by Epicureanism.
The Cyrenaics were known for their skeptical theory of knowledge. They reduced logic to a basic doctrine concerning the criterion of truth. They thought 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 immediate sensation. These sensations are motions which 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 constituting absolute objective knowledge. 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.
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.[9] 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. However some actions which 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 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 behaviour.
