"Doubt is the beginning of wisdom..." - Quote by Aristotle

“Courage is the first of human qualities because it is the quality which guarantees the others.”

“Now the goodness that we have to consider is clearly human goodness, since the good or happiness which we set out to seek was human good and human happiness. But human goodness means in our view excellence of soul, not excellence of body.”

“Without virtue it is difficult to bear gracefully the honors of fortune.”

“Whenever people agree with me I always feel I must be wrong.”

“Doubt is not a pleasant condition, but certainty is absurd.”

“Everyone who observes himself doubting observes a truth, and about that which he observes he is certain; therefore he is certain about a truth. Everyone therefore who doubts whether truth exists has in himself a truth on which not to doubt.... Hence one who can doubt at all ought not to doubt the existence of truth.”

“These possessions of a simpleton being the three I choose and cherish: to care, to be fair, to be humble.”

“The value of actions lies in their timing.”

“Philosophy is an elegant thing, if anyone modestly meddles with it; but if they are conversant with it more than is becoming, it corrupts them.”
