“There is no error more common than that of thinking that those who are the causes or occasions of great tragedies share in the feelings suitable to the tragic mood: no error more fatal than expecting it of them. The martyr in his 'shirt of flame' may be looking on the face of God, but to him who is piling the faggots or loosening the logs for the blast the whole scene is no more than the slaying of an ox is to the butcher, or the felling of a tree to the charcoal burner in the forest, or the fall of a flower to one who is mowing down the grass with a scythe. Great passions are for the great of soul, and great events can be seen only by those who are on a level with them.”

“Truth gains more even by the errors of one who, with due study and preparation, thinks for himself, than by the true opinions of those who only hold them because they do not suffer themselves to think…”

“Reading is the royal road to intellectual eminence...Truly good books are more than mines to those who can understand them. They are the breathings of the great souls of past times. Genius is not embalmed in them, but lives in them perpetually.”

“The peculiar evil of silencing the expression of an opinion is, that it is robbing the human race; posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it. If the opinion is right, they are deprived of the opportunity of exchanging error for truth: if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth, produced by its collision with error.”

“I cannot think well of a man who sports with any woman's feelings; and there may often be a great deal more suffered than a stander-by can judge of.”

“he who thinks great thoughts often makes great errors”
