The experience of climbing Kilimanjaro affected me so powerfully that, for a long time afterward, if I caught myself saying, "I'm not a person who likes to do that activity, eat that food, listen to that music," I would automatically go out and do what I imagined I didn't like.

Science is nothing more than a method of inquiry. The method says an assertion is valid - and will be universally accepted - only if it can be reproduced by others, and thereby independently verified. The impersonal rigor of the method has produced enormously powerful results for 400 years. The scientific method is utterly apolitical.
