"We live in a world which is full of misery and
ignorance, and the plain duty of each and all of us
is to try to make the little corner he can influence
somewhat less miserable and somewhat less ignorant
than it was before he entered it."
Thomas Henry Huxley (1825-95), English biologist.
"On The Physical Basis Of Life" (1868; published in
Collected Essays, vol. 1, 1893).
