The essence of poetry is will and passion.

By conversing with the mighty dead, we imbibe sentiment with knowledge. We become strongly attached to those who can no longer either hurt or serve us, except through the influence which they exert over the mind. We feel the presence of that power which gives immortality to human thoughts and actions, and catch the flame of enthusiasm from all nations and ages.

It is better to drink of deep grief than to taste shallow pleasures.

Books wind into the heart.

To give a reason for anything is to breed a doubt of it.

You shall yourself be judge. Reason, with most people, means their own opinion.

I maintain that there is no common language or medium of understanding between people of education and without it - between those who judge of things from books or from their senses. Ignorance has so far the advantage over learning; for it can make an appeal to you from what you know; but you cannot re-act upon it through that which it is a perfect stranger to. Ignorance is, therefore, power.
