Jerry Bowyer for Forbes reminds us here that Milton Freedman must have gotten his atheism from someone other than Jacob Viner, Professor of Economics, University of Chicago:
[Jacob] Viner concluded that [Adam] Smith was an example of a strand of thought which he called “optimistic providentialism.” This view goes back to the early Christian church fathers, as far back as the time of St. Augustine. It grew to eventually become popular in intellectual circles at the time of Smith. Viner pointed to the extremely important idea he dubbed “providential abundance,” which held that the universe was designed by God to be abundant. The necessities of life were widely distributed by Him, and even the luxuries of life could be had when free people are allowed to pursue self-interest. Man, being in possession of free will, could waste and squander opportunity through plunder, war and empire, but those were not the original design.
