Protagoras adlı düşünürden geriye kalanlar
Protagoras adlı düşünürün yazdıklarından hiçbiri bütün olarak kalmadı. Bu 3 satır bize yalnızca sonraki yazarlar onları kendi eserlerine aktardığı için ulaştı; çoğu zaman da bambaşka bir tartışmanın ortasında.
DK 80 B1, İfade kesin
Sextus Empiricus, Against the Logicians I.60 (c. 200 CE)
Quoted as the opening of a book called Truth, in a survey of what earlier thinkers had made the standard of judgement. Plato had already put the same sentence in Socrates's mouth six centuries earlier, in order to take it apart.
DK 80 B4, İfade kesin
Diogenes Laertius, Lives of the Eminent Philosophers IX.51 (c. 230 CE)
A biographer explaining why Protagoras was prosecuted at Athens and his books burned. The sentence survives because it was the evidence against him.
DK 80 B6a, İfade büyük olasılıkla ona ait
Diogenes Laertius, Lives of the Eminent Philosophers IX.51 (c. 230 CE)
Reported in the same list of what Protagoras was first to say. The teaching that made him rich and, eventually, indefensible in court.
