Famous quotes containing the words physical and/or world:
“The entire construct of the “medical model” of “mental illness”Mwhat is it but an analogy? Between physical medicine and psychiatry: the mind is said to be subject to disease in the same manner as the body. But whereas in physical medicine there are verifiable physiological proofs—in damaged or affected tissue, bacteria, inflammation, cellular irregularity—in mental illness alleged socially unacceptable behavior is taken as a symptom, even as proof, of pathology.”
—Kate Millett (b. 1934)
“This might be the end of the world. If Joe lost we were back in slavery and beyond help. It would all be true, the accusations that we were lower types of human beings. Only a little higher than apes. True that we were stupid and ugly and lazy and dirty and, unlucky and worst of all, that God Himself hated us and ordained us to be hewers of wood and drawers of water, forever and ever, world without end.”
—Maya Angelou (b. 1928)
