[Pinker] conflates scientific knowledge with knowledge as such. In his view, anybody who has studied any phenomena that are studied by science has been a scientist...If they were interested in the mind, then they were early versions of brain scientists. If they investigated human nature, then they were social psychologists or behavioral economists avant la lettre. Leon Wieseltier pens a response to Steven Pinker's essay on scientism, both in the pages of the New Republic. Others, including some prominent atheists, have taken issue with Pinker as well.
Why do so many scientists believe in God? "Modern science did not emerge 400 years ago to challenge religion, the orthodoxy of the past 2,000 years. Generations of thinkers and experimenters and observers - often themselves churchmen - wanted to explain how God worked his wonders. Modern physics began with a desire to explain the clockwork of God's creation. Modern geology grew at least partly out of searches for evidence of Noah's flood. Modern biology owes much to the urge to marvel at the intricacy of Divine providence. But the scientists - a word coined only in 1833 - who hoped to find God somehow painted Him out of the picture... So although the debate did not start out as science versus religion, that is how many people now see it. Paradoxically, this is not how many scientists see it."
