Famous quotes containing the words crystal and/or habit:
“Comets, importing change of times and states,
Brandish your crystal tresses in the sky.”
—William Shakespeare (1564–1616)
“The way of Providence is a little rude. The habit of the snake and spider, the snap of the tiger and other leapers and bloody jumpers, the crackle of the bones of his prey in the coil of the anaconda,—these are in the system, and our habits like theirs. You have just dined, and however scrupulously the slaughter-house is concealed in the graceful distance of miles, there is complicity, expensive races,—race living at the expense of race.”
—Ralph Waldo Emerson (1803–1882)
