The lichen on the rocks is a rude and simple shield which beginning and imperfect Nature suspended there. Still hangs her wrinkledtrophy.
Henry David ThoreauWhat is called common sense is excellent in its department, and as invaluable as the virtue of conformity in the army and navy,--for there must be subordination,--but uncommon sense, that sense which is common only to the wisest, is as much more excellent as it is more rare.
Henry David ThoreauSo behave that the odor of your actions may enhance the general sweetness of the atmosphere, that when we behold or scent a flower, we may not be reminded how inconsistent your deeds are with it; for all odor is but one form of advertisement of a moral quality, and if fair actions had not been performed, the lily would not smell sweet. The foul slime stands for the sloth and vice of man, the decay of humanity; the fragrant flower that springs from it, for the purity and courage which are immortal.
Henry David ThoreauWe have heard much about the poetry of mathematics, but very little of it has as yet been sung. The ancients had a juster notion of their poetic value than we.

Henry David ThoreauThe New Testament is an invaluable book, though I confess to having been slightly prejudiced against it in my very early days by the church and the Sabbath school, so that it seemed, before I read it, to be the yellowest book in the catalogue. Yet I early escaped from their meshes. It was hard to get the commentaries out of one's head and taste its true flavor.
