Famous quotes containing the words rational and/or expressions:
“The poet makes himself a seer by a long, prodigious, and rational disordering of all the senses. Every form of love, of suffering, of madness; he searches himself, he consumes all the poisons in him, and keeps only their quintessences.”
—Arthur Rimbaud (1854–1891)
“Preschoolers think and talk in concrete, literal terms. When they hear a phrase such as “losing your temper,” they may wonder where the lost temper can be found. Other expressions they may hear in times of crisis—raising your voice, crying your eyes out, going to pieces, falling apart, picking on each other, you follow in your father’s footsteps—may be perplexing.”
—Ruth Formanek (20th century)
