Know yourself was proposed by Socrates.

Know thyself is said to be one of the three mottos engraved in the Temple of Apollo at Delphi, and it is also the most famous of them. The other two sentences are "You are" (ει') and "Don't pass" (μηδεν αγαν).

It may be said that this sentence comes from one of the seven sages of ancient Greece, Caron (Χλων) of Sparta, or it may be said that it comes from Thales, or it may be said that it comes from Socrates. The traditional interpretation of this sentence is to advise people to be self-aware and understand that people are only human beings, not gods.
