"When a person starts on the discovery of the Absolute by the light of the reason only, without the assistance of the senses, and never desists until by pure intelligence he arrives at the perception of the Absolute Good, he at last finds himself at the end of the intellectual world. . . . dialectics then is the coping stone of the sciences, and is set over them; it would not be right to place any other science higher, the nature of knowledge cannot further go."
Plato
