Life

He was a native of Megara. He probably lived after the time of Euclid of Megara, which makes it unlikely that he was a pupil of Euclid, as stated by some;[3] and others state that he was the pupil of Thrasymachus of Corinth,[4] or of Pasicles, the brother of Crates of Thebes.[5] According to one account, he engaged in dialectic encounters with Diodorus Cronus at the court of Ptolemy Soter; according to another, he did not comply with the invitation of the king, to go to Alexandria. We are further told that Demetrius, the son of Antigonus, honoured him no less, spared his house at the capture of Megara, and offered him indemnity for the injury which it had received, which, however, Stilpo declined.[6] Uniting elevated sentiment with gentleness and patience, he, as Plutarch says,[7] was an ornament to his country and friends, and had his acquaintance sought by kings. His original propensity to wine and voluptuousness he is said to have entirely overcome;[8] in inventive power and dialectic art to have surpassed his contemporaries, and to have inspired almost all Greece with a devotion to Megarian philosophy. A number of distinguished men too are named, whom he is said to have drawn away from Theophrastus, Aristotle of Cyrene, and others, and attached to himself;[9] among others Crates the Cynic, and Zeno, the founder of the Stoic school.[4] Among his followers were Menedemus and Asclepiades, the leaders of the Eretrian school of philosophy. One of his pupils, Nicarete, was also said to have been his mistress.[10] Stilpo was praised for his political wisdom, his simple, straightforward disposition, and the equanimity with which he tolerated his rebellious daughter.[11] Cicero relates that Stilpo's friends had described him as "vehemently addicted to wine and women",[12] but that his philosophy eliminated his inclinations.[13]
Philosophy

Of the dialogues ascribed to him, we know only the titles. He belonged to the Megarian school of philosophy, but we learn only a little about his doctrines in the few fragments and sayings of his which are quoted.
Logic

Stilpo argued that the genus, the universal, is not contained in the individual and concrete. "Whoever speaks of any person, speaks of no-one, for he neither speaks of this one nor that. For why should it rather be of this one than that? Hence it is not of this one".[14] One of his examples was that "the vegetable is not what is here shown. For a vegetable existed ten thousand years ago, therefore this here is not a vegetable".[14] According to Simplicius, "the so-called Megarians took it as ascertained that what has different determinations is different, and that the diverse are separated one from the other, they seemed to prove that each thing is separated from itself. Hence since the musical Socrates is another determination from the wise Socrates, Socrates was separated from himself."[15]

Thus one thing cannot be predicated of another, that is, the essence of things cannot be reached by means of predicates. Plutarch quotes Stilpo as arguing:

To be a horse differs from to be running. For being asked the definition of the one and of the other, we do not give the same for them both; and therefore those err who predicate the one of the other. For if good is the same with people, and to run the same with a horse, how is good affirmed also of food and medicine, and again (by Jupiter) to run of a lion and a dog? But if the predicate is different, then we do not rightly say that a person is good, and a horse runs.[16]

Plutarch remarks here that Colotes attacked Stilpo in a bombastic manner as though he ignored common life: "for how shall we live, if we cannot style a man good, nor a man a captain, but must separately name a man a man, good good, and a captain a captain." But Plutarch, in turn, replied, "but what man lived any the worse for this? Is there any man who hears this said, and who does not understand it to be the speech of a man who rallies gallantly, and proposes to others this logical question to exercise their mind?"
Ethics

Stilpo seems to have been interested in Virtue,[17] and its self-sufficiency. He maintained that the wise man ought not only to overcome every evil, but not even to be affected by any, not even to feel it,[18] showing, perhaps, how closely allied Stilpo was to the contemporary Cynics:

For Stilpo, after his country was captured and his children and his wife lost, as he emerged from the general desolation alone and yet happy, spoke as follows to Demetrius, called Sacker of Cities because of the destruction he brought upon them, in answer to the question whether he had lost anything: "I have all my goods with me!"
— Seneca, Wikisource-logo.svg Epistles, 9.18.

This story was an inspiration for Friedrich Klinger's Sturm und Drang play Stilpo und seine Kinder (Stilpo and his Children) written in 1777 and published in 1780.[19]

A one-page fragment or paraphrase from a work concerning exile is preserved in the writings of Teles of Megara, a 3rd-century BC Cynic. In this fragment, Stilpo divides the good into three parts: goods of the soul, goods of the body, and external goods. He then demonstrates that exile does not deprive a person of any of these three goods.[20]
