Hegesias (Greek: Ἡγησίας; fl. 290 BC) of Cyrene was a Cyrenaic philosopher. He argued that happiness is impossible to achieve, and that the goal of life was the avoidance of pain and sorrow. Conventional values such as wealth, poverty, freedom, and slavery are all indifferent and produce no more pleasure than pain. Cicero claims that Hegesias wrote a book called Death by Starvation, which persuaded so many people that death is more desirable than life, that Hegesias was banned from teaching in Alexandria. It has been thought by some that Hegesias was influenced by Buddhist teachings.
He is said by Diogenes Laërtius to have been the pupil of Paraebates, who was a pupil of Epitimedes, who was a pupil of Antipater of Cyrene, who was a pupil of Aristippus (435-c.360 BC). He was the fellow-student of Anniceris, from whom, however, he differed by presenting in its most nihilistic form the system which Anniceris softened and improved.
Hegesias followed Aristippus in considering pleasure as the goal of life; but, the view which he took of human life was more pessimistic. Happiness, he said, could not be the goal of life, because it is not attainable, and therefore concluded that the wise person's only goal should be to become free from pain and sorrow. Since, too, every person is self-sufficient, all external goods were rejected as not being true sources of pleasure.
Complete happiness cannot possibly exist; for that the body is full of many sensations, and that the mind sympathizes with the body, and is troubled when that is troubled, and also that fortune prevents many things which we cherished in anticipation; so that for all these reasons, perfect happiness eludes our grasp. Moreover, that both life and death are desirable. They also say that there is nothing naturally pleasant or unpleasant, but that owing to want, or rarity, or satiety, some people are pleased and some vexed; and that wealth and poverty have no influence at all on pleasure, for that rich people are not affected by pleasure in a different manner from poor people. In the same way they say that slavery and freedom are things indifferent, if measured by the standard of pleasure, and nobility and baseness of birth, and glory and infamy. They add that, for the foolish person it is expedient to live, but to the wise person it is a matter of indifference; and that the wise person will do everything for his own sake; for that he will not consider any one else of equal importance with himself; and he will see that if he were to obtain ever such great advantages from any one else, they would not be equal to what he could himself bestow.
Hence the sage ought to regard nothing but himself; action is quite indifferent; and if action, so also is life, which, therefore, is in no way more desirable than death.
The wise person would not be so much absorbed in the pursuit of what is good, as in the attempt to avoid what is bad, considering the chief good to be living free from all trouble and pain: and that this end was attained best by those who looked upon the efficient causes of pleasure as indifferent.
None of this, however, is as strong as the testimony of Cicero, who claims that Hegesias wrote a book called Death by Starvation (Greek: ἀποκαρτερῶν), in which a man who has resolved to starve himself is introduced as representing to his friends that death is actually more to be desired than life, and that the gloomy descriptions of human misery which this work contained were so overpowering that they inspired many people to kill themselves, in consequence of which the author received the surname of Death-persuader (Peisithanatos). This book was published at Alexandria, where he was, in consequence, forbidden to teach by king Ptolemy II Philadelphus (285-246 BC).
Hegesias of Cyrene, whose ruler may have been Magas of Cyrene, an apparent recipient of Buddhist missionaries from the Indian king Ashoka according to the latter's Edicts, is sometimes thought to have been influenced by Buddhist teachings.
