Famous quotes containing the word biological:
“Man’s biological weakness is the condition of human culture.”
—Erich Fromm (1900–1980)
“No poetic phantasy
but a biological reality,
a fact: I am an entity
like bird, insect, plant
or sea-plant cell;
I live; I am alive.”
—Hilda Doolittle (1886–1961)
“When human beings have been fascinated by the contemplation of their own hearts, the more intricate biological pattern of the female has become a model for the artist, the mystic, and the saint. When mankind turns instead to what can be done, altered, built, invented, in the outer world, all natural properties of men, animals, or metals become handicaps to be altered rather than clues to be followed.”
—Margaret Mead (1901–1978)
