Famous quotes containing the words blind and/or experiments:
“When you’ve been blind as long as I have, you learn to see through your senses. I can’t explain it exactly, but you get a feeling about people when you meet them. You see a picture of them in your mind. Not just what they look like, but what they really are. You see them much more clearly than you do with your eyes. Maybe that’s why they say looks are deceptive.”
—George Bricker. Jean Yarbrough. Helen Page (Jane Adams)
“There are three principal means of acquiring knowledge available to us: observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination. Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.”
—Denis Diderot (1713–1784)
