Scientists like Dawkins, Singer, Pinker, Lewontin and Monod do not respect the epistemic divide when they posit the theory of evolution as objective truth which by definition cannot be subjected to the scientific method (observer problem.) When they do this, these scientists reflect poorly on other scientists. I beg to differ; it tends to reflect poorly on them. Like the old joke about peeing on yourself while wearing dark pants--it gives you a warm feeling but nobody notices.
Only with that crowd, they're wearing light khaki.
