The following are the contents of the first book of The Refutation of all Heresies.
We propose to furnish an account of the tenets of natural philosophers, and who these are, as well as the tenets of moral philosophers, and who these are; and thirdly, the tenets of logicians, and who these logicians are.
Among natural philosophers may be enumerated Thales, Pythagoras, Empedocles, Heraclitus, Anaximander, Anaximenes, Anaxagoras, Archelaus, Parmenides, Leucippus, Democritus, Xenophanes, Ecphantus, Hippo.
Among moral philosophers are Socrates, pupil of Archelaus the physicist, (and) Plato the pupil of Socrates. This (speculator) combined three systems of philosophy.
Among logicians is Aristotle, pupil of Plato. He systematized the art of dialectics. Among the Stoic (logicians) were Chrysippus (and) Zeno. Epicurus, however, advanced an opinion almost contrary to all philosophers. Pyrrho was an Academic; this (speculator) taught the incomprehensibility of everything. The Brahmins among the Indians, and the Druids among the Celts, and Hesiod (devoted themselves to philosophic pursuits).
