"I know that I know nothing" (Ancient Greek: ἓν οἶδα ὅτι οὐδὲν οἶδα hen oída hoti oudén oída; Latin: scio me nihil scire or scio me nescire) is a well-known saying which is attributed to the Greek philosopher Socrates. The preferred saying, as recorded in much literature, is "The only real wisdom is knowing you know nothing".
— This man, on one hand, believes that he knows something, while not
knowing [anything]. On the other hand, I - equally ignorant - do not
believe [that I know anything].
—So now I do not know what virtue is; perhaps you knew before you
contacted me, but now you are certainly like one who does not know. (trans. G.M.A. Grube)
Socrates begins all wisdom with wondering, thus one must begin with admitting one's ignorance.
