The development of civilization and industry in general has always shown itself so active in the destruction of forests that everything that has been done for their conservation and production is completely insignificant in comparison.Karl Marx
The intuition of the moral sentiment is an insight of the perfection of the laws of the soul. These laws execute themselves. They are out of time, out of space, and not subject to circumstance.Ralph Waldo Emerson
Good is positive. Evil is merely privative, not absolute: it is like cold, which is the privation of heat. All evil is so much death or nonentity. Benevolence is absolute and real. So much benevolence as a man hath, so much life hath he.Ralph Waldo Emerson
Truth is handsomer than the affectation of love. Your goodness must have some edge to it, else it is none.Ralph Waldo Emerson
As we are, so we associate. The good, by affinity, seek the good; the vile, by affinity, the vile. Thus of their own volition, souls proceed into Heaven, into Hell.Ralph Waldo Emerson
