Famous quotes containing the words biological, theories and/or aging:
“It is not the literal past that rules us, save, possibly, in a biological sense. It is images of the past.... Each new historical era mirrors itself in the picture and active mythology of its past or of a past borrowed from other cultures. It tests its sense of identity, of regress or new achievement against that past.”
—George Steiner (b. 1929)
“The theories and speculations of men concern us more than their puny accomplishment. It is with a certain coldness and languor that we loiter about the actual and so-called practical.”
—Henry David Thoreau (1817–1862)
“The politics of the exile are fever,
revenge, daydream,
theater of the aging convalescent.
You wait in the wings and rehearse.
You wait and wait.”
—Marge Piercy (b. 1936)
