" Man is the measure of all things, " said the Sophist Protagoras (c. 485-410 BC).

诡辩学家普罗塔哥拉斯(Protagoras，约公元前四八五一公元前四一O年)曾说过：“人是衡量一切的尺度。”

Protagoras said that objective truth was an illusion because " man is the measure of all things."

普罗泰戈拉说客观真理是一种幻觉，因为“人是万物的尺度” 。

But it really goes back all the way to the Greek philosopher Protagoras, if not farther back.

但它真的可以追溯到希腊哲学家 Protagoras，如果不是更早的话。
