Just as the twig is bent, the tree’s inclined.”
—Alexander Pope (1688–1744)
“And what avails it that science has come to treat space and time as simply forms of thought, and the material world as hypothetical, and withal our pretension of property and even of self-hood are fading with the rest, if, at last, even our thoughts are not finalities, but the incessant flowing and ascension reach these also, and each thought which yesterday was a finality, to-day is yielding to a larger generalization?”
—Ralph Waldo Emerson (1803–1882)
“The terrorist and the policeman both come from the same basket. Revolution, legality—counter-moves in the same game; forms of idleness at bottom identical.”
—Joseph Conrad (1857–1924)
