"We cannot feel strongly toward the totally unlike because it is unimaginable, unrealizable; nor yet toward the wholly like because it is stale -- identity must always be dull company. The power of other natures over us lies in a stimulating difference which causes excitement and opens communication, in ideas similar to our own but not identical, in states of mind attainable but not actual."
"You are ninety-eight cents' worth of cosmic star dust floating at the obscure edge of an ordinary galaxy, and yet you are the center of your own world; to friends and family, you may be precious beyond all worth. On one day, humanity seems the apex of all things beautiful, generous, mindful; another day, it seems a stupid beast."
"If winds are the spirit of the sky's ocean, the clouds are the texture. Their is easily the most uninhibited dominion of the earth. Nothing in physical shape is too fantastic for them. They can be round as apples or as fine as string, as dense as a jungle, as wispy as a whiff of down, as mild as puddle water or as potent as the belch of a volcano. Some are thunderous anvils formed by violent up drafts from the warm earth. Some are ragged coattails of storms that have passed. Some are stagnant blankets of warm air resting on cold. I have seen clouds in the dawn that looked like a pink Sultan with his pale harem maidens and a yellow slob of eunuch lolling impotent in the background."
"In the visible world, the Milky Way is a tiny fragment; within this fragment, the solar system is an infinitesimal speck, and of this speck our planet is a microscopic dot. On this dot, tiny lumps of impure carbon and water, of complicated structure, with somewhat unusual physical and chemical properties, crawl about for a few years, until they are dissolved again into the elements of which they are compounded. They divide their time between labour designed to postpone the moment of dissolution for themselves and frantic struggles to hasten it for others of their kind."
