There are three classes of men; lovers of wisdom, lovers of honor, and lovers of gain.
Wisdom alone is the science of other sciences.
Wise men talk because they have something to say; fools, because they have to say something.
A good decision is based on knowledge and not on numbers.
Good actions give strength to ourselves and inspire good actions in others.
Love is a serious mental disease.
Bodily exercise, when compulsory, does no harm to the body; but knowledge which is acquired under compulsion obtains no hold on the mind.
Wise men speak because they have something to say; Fools because they have to say something.
Knowledge without justice ought to be called cunning rather than wisdom.
