It is a base thing for a man to wax old in careless self-neglect before he has lifted up his eyes and seen what manner of man he was made to be, in the full perfection of bodily strength and beauty. But these glories are withheld from him who is guilty of self-neglect, for they are not wont to blaze forth unbidden.
SocratesTo know, is to know that you know nothing. That is the meaning of true knowledge. For a man who claims to have knowledge, while actually knowing nothing, is less smarter than you, who claim to know nothing.
Socrates
