"Curiosity is one of the permanent and certain characteristics of a vigorous intellect."

“I will be conquered; I will not capitulate.”

“I fly from pleasure," said the prince, "because pleasure has ceased to please; I am lonely because I am miserable, and am unwilling to cloud with my presence the happiness of others.”

“It is not by comparing line with line, that the merit of great works is to be estimated, but by their general effects and ultimate result. It is easy to note a weak line, and write one more vigorous in its place; to find a happiness of expression in the original, and transplant it by force into the version: but what is given to the parts may be subducted from the whole, and the reader may be weary, though the critick may commend. Works of imagination excel by their allurement and delight; by their power of attracting and detaining the attention. That book is good in vain, which the reader throws away. He only is the master, who keeps the mind in pleasing captivity; whose pages are perused with eagerness, and in hope of new pleasure are perused again; and whose conclusion is perceived with an eye of sorrow, such as the traveller casts upon departing day.”

“It might as well be said, "Who drives fat oxen should himself be fat.”

“There will always be a part, and always a very large part of every community, that have no care but for themselves, and whose care for themselves reaches little further than impatience of immediate pain, and eagerness for the nearest good.”

“Human life is everywhere a state in which much is to be endured and little to be enjoyed.”
