True humor springs not more from the head than from the heart. It is not contempt; its essence is love. It issues not in laughter, but in still smiles, which lie far deeper.
Thomas CarlyleHeroes have gone out; quacks have come in; the reign of quacks has not ended with the nineteenth century. The sceptre is held with a firmer grasp; the empire has a wider boundary. We are all the slaves of quackery in one shape or another. Indeed, one portion of our being is always playing the successful quack to the other.
Thomas CarlyleOf all the things which man can do or make here below, by far the most momentous, wonderful, and worthy are the things we call books.
