Henry David ThoreauAll that are printed and bound are not books; they do not necessarily belong to letters, but are oftener to be ranked with the other luxuries and appendages of civilized life. Base wares are palmed off under a thousand disguises.
Henry David ThoreauIf you can't explain it to a six year old, you don't understand it yourself. Rather than love, than money, than fame, give me truth.
Henry David ThoreauThe majority of the men of the North, and of the South and East and West, are not men of principle. If they vote, they do not sendmen to Congress on errands of humanity; but while their brothers and sisters are being scourged and hung for loving liberty,... it is the mismanagement of wood and iron and stone and gold which concerns them.
Henry David ThoreauIt is remarkable that, notwithstanding the universal favor with which the New Testament is outwardly received, and even the bigotry with which it is defended, there is no hospitality shown to, there is no appreciation of, the order of truth with which it deals. I know of no book that has so few readers. There is none so truly strange, and heretical, and unpopular. To Christians, no less than Greeks and Jews, it is foolishness and a stumbling-block.
