Famous quotes containing the words heat and/or exchange:
“For my part, when I enter most intimately into what I call myself, I always stumble on some particular perception or other, of heat or cold, light or shade, love or hatred, pain or pleasure. I never can catch myself at any time without a perception, and never can observe anything but the perception.”
—David Hume (1711–1776)
“Love is often nothing but a favorable exchange between two people who get the most of what they can expect, considering their value on the personality market.”
—Erich Fromm (1900–1980)
