The book exists for us perchance which will explain our miracles and and reveal new ones. The at present unutterable things we may find somewhere uttered. These same questions that disturb and puzzle and confound us have in their turn occurred to all the wise men; not one has been omitted; and each has answered them, according to his ability, by his words and his life.
Henry David ThoreauWhen a sixth of the population of a nation which has undertaken to be the refuge of liberty are slaves, and a whole country [Mexico] is unjustly overrun and conquered by a foreign army, and subjected to military law, I think that it is not too soon for honest men to rebel and revolutionize. What makes this duty the more urgent is the fact that the country so overrun is not our own, but ours is the invading army.
Henry David ThoreauThe indescribable innocence and beneficence of Nature-of sun and wind and rain, of summer and winter-such health, such cheer, they afford forever! and such sympathy have they ever with our race, that all Nature would be affected, and the sun's brightness fade, and the winds would sigh humanely, and the clouds rain tears, and the woods shed their leaves and put on mourning in midsummer, if any man should ever for a just cause grieve.
