No theory changes what it is a theory about. Nothing is changed because we look at it, talk about it, or analyze it in a new way. Keats drank confusion to Newton for analyzing the rainbow, but the rainbow remained as beautiful as ever and became for many even more beautiful. Man has not changed because we look at him, talk about him, and analyze him scientifically. ... What does change is our chance of doing something about the subject of a theory. Newton's analysis of the light in a rainbow was a step in the direction of the laser.
