Since the main object of the Stoic school is the training of the will, and since wisdom as such is only a means to an end, the dogmatic form that corresponds to Oriental modes of thought and the despotic system of contemporary government prevails throughout its teachings. Hence we can understand how this somewhat coarse, wire-drawn, as it were, but effective form of philosophy dominates the whole world from this time forward till about the second century A.D. In essentials it represents a revival of Heraclitism, just as the antithetical philosophy of Epicureanism, which prevailed for the same length of time, is in essence reminiscent of the Abderitic system.
Epicurus (born 342) was the son of an Athenian, but born at Samos. Thus he had opportunities of making himself acquainted with the philosophy of Democritus, which was more highly esteemed in Ionia than at Athens. He did not care for learning for its own sake, however, but for the sake of its practical application. In this respect, as also in his consistent materialism, he is closely akin to the Stoic school.
In dogmatic positiveness and immutability Epicurus far surpasses even the Stoic philosophy. With him the main consideration is a mode of life which induces a tranquil cheerfulness of temper by the refusal to admit all disquieting thoughts (as of death, immortality or divine punishment) and troublesome passions, and by which his followers, while here below, become partakers of the felicity of the gods. This quietist philosophy harmonised with the ideals of life which obtained at that period, and the ardent exaltation of friendship among this free-thinking fellowship and their ideal of human freedom and dignity atone in some degree for the hollowness of their theory of life.
Finally Scepticism takes the form of a school in Greece with Pyrrho, who died in the same year as Epicurus, 270 B.C. He, too, is only solicitous for tranquillity of mind, but he does not win it by dogmatic faith in this system of doctrine or that, but in believing nothing whatever, in thinking nothing right and nothing important. This thorough-going scepticism is bound to doubt even itself. As a result it neutralises itself and thus marks the spontaneous dissolution of Hellenic philosophy.
