Famous quotes containing the words similar, structures and/or organisms:
“The question that’s probably uppermost in the child’s mind is: Why do my parents want to have a baby? Don’t they love me? And if they love me, why do they need another one? Aren’t I enough? Imagine for a minute yourself in a similar situation. Your husband comes home and says: “Honey I love you so much, I’ve decided to go get another wife so I can have two.” How would you feel?”
—Lawrence Balter (20th century)
“It is clear that all verbal structures with meaning are verbal imitations of that elusive psychological and physiological process known as thought, a process stumbling through emotional entanglements, sudden irrational convictions, involuntary gleams of insight, rationalized prejudices, and blocks of panic and inertia, finally to reach a completely incommunicable intuition.”
—Northrop Frye (b. 1912)
“The white man regards the universe as a gigantic machine hurtling through time and space to its final destruction: individuals in it are but tiny organisms with private lives that lead to private deaths: personal power, success and fame are the absolute measures of values, the things to live for. This outlook on life divides the universe into a host of individual little entities which cannot help being in constant conflict thereby hastening the approach of the hour of their final destruction.”
—Policy statement, 1944, of the Youth League of the African National Congress. pt. 2, ch. 4, Fatima Meer, Higher than Hope (1988)
