There is science, and then there is Scientism.
Science is a method. Hypotheses and theories are always provisional, are always approximate, and are always open to change, being refined and even overthrown.
Scientism is the belief that science is the only way to the truth (in fact it is the Truth) and whatever it states is the Truth. Such people are close to being humorless fanatics than anything else, and they certainly cannot handle the slightest bit of cognitive dissonance. Actually, science is their God.
I heard of Rupert Sheldrake many years ago, and have read some of his books. Thank God for the internet, since it gives him and other like him more exposure.
