The seat of knowledge is in the head; of wisdom, in the heart. We are sure to judge wrong, if we do not feel right.

It's not given to people to judge what's right or wrong. People have eternally been mistaken and will be mistaken, and in nothing more than in what they consider right and wrong.

There is a wisdom of the head, and a wisdom of the heart.

The world dread nothing so much as being convinced of their errors.

That which is not, shall never be; that which is, shall never cease to be. To the wise, these truths are self-evident.

Those who have the largest hearts, have the soundest understandings; and he is the truest philosopher who can forget himself.
