Science Quotes by Protagoras (2 quotes)
Concerning the gods, I have no means of knowing either that they exist or that they do not exist, nor what sort of form they may have; there are many reasons why knowledge on this subject is not possible, owing to the lack of evidence and the shortness of human life.
— Protagoras
Protagoras, fr. 1, quoted in E. Hussey, The Pre-Socratics (1972), 109.

Quotes by others about Protagoras (1)
Note the saying of Protagoras that man is the measure of things. With the senses man measures perceptible things, with the intellect he measures intelligible things, and he attains unto supra-intelligible things transcendently
Dialog, 'De Beryllo' (1458). As translated in Jasper Hopkins, Complete Philosophical and Theological Treatises of Nicholas of Cusa: De visione Dei (2001), Vol. 2, 793.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
