Atheists are those most seriously tempted to devolve into scientism.
Atheists are the most susceptible to believing that science can and will tell us all things valuable.
To live like that takes a lot of faith.
To believe in scientism:
. One needs to have faith that our minds cannot be fooled.
. One needs to have faith that our senses are never wrong, and
. One needs to have faith that the people whose earlier research upon which our own beliefs rest never lied or made mistakes.
Examples you say? Freud, Kinsey, Mead, Rand, Haeckel, Galton, Skinner. Or how about East Asian cloning, or Piltdown Man. Or maybe you prefer ‘The Secret Gospel of Mark’ which turned out to be written by Columbia University historian Morton Smith. Or the common textbook icons of Darwinian evolution in action that have all been discredited:
. Haeckel’s faked embryo drawings, (Which I've been told have reappeared in Dawkins' latest book)
. Mutant four winged fruit flies that are in reality dysfunctional, and
. Peppered moths that in the real world don't rest on tree trunks; the photographs were staged.
. Oh and how about our high school biology textbooks that neglect to mention that the beaks of Darwin’s Finches returned to normal after the rains returned. No net evolution occurred. Like many species, the finch has an average beak size that fluctuates within a given range.
. Or how about Miller & Oparin “creating” life out of primordial earth’s ammonia, methane and hydrogen?
Of course the main reason that we shouldn’t naively believe in scientism is that scientism itself cannot be proven by science.
But that doesn’t stop atheists, for science is all they’ve got. Well, that and an incredible faith.
