Discretion is the perfection of reason, and a guide to us in all the duties of life; cunning is a kind of instinct, that only looks out after our immediate interests and welfare. Discretion is only found in men of strong sense and good understanding; cunning is often to be met with in brutes themselves, and in persons who are but the fewest removes from them.
I am amused when goody-goodies proclaim, from the safety of their armchairs, that children are naturally prejudice-free, that they only learn to "hate" from listening to bigoted adults. Nonsense. Tolerance is a learned trait, like riding a bike or playing the piano. Those of us who actually live among children, who see them in their natural environment, know the truth: Left to their own devices, children will gang up on and abuse anyone who is even slightly different from the norm.
