"The natural truths of science, physical, moral, social, political, material, are all from God—as those of the supernatural order are. Man abused supernatural truths in the medieval time, as well as used them; and now man uses natural truths, as well as abuses them. I am not determining which of the two abuses is the greater profanation, I only say that the one age is not all light, the other all darkness; and I think that, in matter of fact, more can be said for this age than you seem to allow."
