Famous quotes containing the words heat and/or exchange:
“For it is wretchedness that endures, shedding its cancerous light on all it approaches:
Words spoken in the heat of passion, that might have been retracted in good time,
All good intentions, all that was arguable.”
—John Ashbery (b. 1927)
“Ants are so much like human beings as to be an embarrassment. They farm fungi, raise aphids as livestock, launch armies into war, use chemical sprays to alarm and confuse enemies, capture slaves, engage in child labor, exchange information ceaselessly. They do everything but watch television.”
—Lewis Thomas (b. 1913)
