This hostility to science, in the face of its obvious triumphs and benefits, is … evidence that it is something outside the mainstream of human devel… - Carl Sagan

I believe a partial answer can be found in the responses made to the Mariner IV findings by political leaders, by Mr. Billy Graham, and by other American divines - often sure barometers of common attitudes. They were unmistakably relieved. Finding life beyond the Earth - particularly intelligent life, although this is highly unlikely on Mars - wrenches at our secret hope that Man is the pinnacle of creation, a contention which no other species on our planet can now challenge. Even simple forms of extraterrestrial life may have abilities and adaptations denied to us. The discovery of life on some other world will, among many things, be for us a humbling experience.

If I were to propose to you that my arm could be in this position or in that position but it would be forbidden by the laws of nature to be in some intermediate position, that would likely strike you as absurd, as contrary to experience. And yet on the subatomic level, there is a quantization of energy and position and momentum. The reason that it seems counterintuitive is that is that we are not ordinarily down at the level of the very small, where quantum effects dominate.

It is the tension between creativity and skepticism that has produced the stunning and unexpected findings of science.
