“All I really know is the extent of my own ignorance”

“Socrates: 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].”

“Ignorance, the root and stem of all evil.”

“And whenever any one informs us that he has found a man who knows all the arts, and all things else that anybody knows, and every single thing with a higher degree of accuracy than any other man –whoever tells us this, I think that we can only imagine him to be a simple creature who is likely to have been deceived by some wizard or actor whom he met, and whom he thought all-knowing, because he himself was unable to analyze the nature of knowledge and ignorance and imitation.”

“And isn't it a bad thing to be deceived about the truth, and a good thing to know what the truth is? For I assume that by knowing the truth you mean knowing things as they really are.”

“For to fear death, my friends, is only to think ourselves wise without really being wise, for it is to think that we know what we do not know. For no one knows whether death may not be the greatest good that can happen to man.”

“The rhetorician need not know the truth about things; he has only to discover some way of persuading the ignorant that he has more knowledge than those who know.”
