Chemistry Topics

Science with its retorts would have put me to sleep; it was the opportunity to be ignorant that I improved. It suggested to me that there was something to be seen if one had eyes. It made a believer of me more than before. I believed that the woods were not tenantless, but choke-full of honest spirits as good as myself any day,—not an empty chamber, in which chemistry was left to work alone, but an inhabited house,—and for a few moments I enjoyed fellowship with them.
—Henry David Thoreau (1817–1862)

Soon my companions were lost to my sight behind the mountain ridge in my rear, which still seemed ever retreating before me, and I climbed alone over huge rocks, loosely poised, a mile or more, still edging toward the clouds; for though the day was clear elsewhere, the summit was concealed by mist. The mountain seemed a vast aggregation of loose rocks, as if some time it had rained rocks, and they lay as they fell on the mountain sides, nowhere fairly at rest, but leaning on each other, all rocking stones, with cavities between, but scarcely any soil or smoother shelf. They were the raw materials of a planet dropped from an unseen quarry, which the vast chemistry of nature would anon work up, or work down, into the smiling and verdant plains and valleys of earth. This was the undone extremity of the globe; as in lignite we see coal in the process of formation.
—Henry David Thoreau (1817–1862)

If thought makes free, so does the moral sentiment. The mixtures of spiritual chemistry refuse to be analyzed.
—Ralph Waldo Emerson (1803–1882)
