Parménide

What is, is; what is not can neither be thought nor said: being has neither birth nor end.

Life

Parmenides of Elea (c. 515-450 BC) was a Greek philosopher from southern Italy. He wrote a poem, On Nature, of which fragments survive: a goddess distinguishes the way of truth, which says that being is and can neither come to be nor perish, from the way of mortal opinions. His appeal to reason alone against the senses influenced Plato and later metaphysics, and his follower Zeno defended him with paradoxes.

On Nature (poem, fragments)

The Way of Truth claims that being is one, without birth or end, and that what is not cannot be thought.

In his own words

« For thinking and being are the same. »

τὸ γὰρ αὐτὸ νοεῖν ἐστίν τε καὶ εἶναι.

Parménide, fragment DK 28 B3
« One must say and think that what is, is: for being is, and nothing is not. »

Χρὴ τὸ λέγειν τε νοεῖν τ΄ ἐὸν ἔμμεναι· ἔστι γὰρ εἶναι, μηδὲν δ΄ οὐκ ἔστιν

Parménide, fragment DK 28 B6
« It never was nor will be, since it is now, all together, one, continuous. »

οὐδέ ποτ΄ ἦν οὐδ΄ ἔσται, ἐπεὶ νῦν ἔστιν ὁμοῦ πᾶν, ἕν, συνεχές

Parménide, fragment DK 28 B8
