The tract "The Bible vs. The Evolution Theory" (1898) argued that, while the modern age benefits from accumulated knowledge, humans of earlier centuries had greater abilities, and that human intellect has degraded over the centuries. It points to superior examples of art, poetry and even science in previous eras:
"In the Sciences. Of present day art and sciences special boast is made; and we are ready to admit generally the claim, accounting for it as before explained. Nevertheless, it behooves us to remember that the people of the past accomplished wonders without our modern appliances... We are not to forget, either, that some of the valuable arts of the past were so thoroughly lost that even with all our present-day enlightenment they have not yet been re-discovered: for instance, the process of manufacturing flexible glass; and the process of tempering steel which gave the swords of Damascus a world-wide fame for flexibility; and the process of tempering copper so as to render it useful for tools. And while considering these matters we are to remember that the Scriptures indicate not only that the Children of Israel became much degraded through their several centuries of bondage in Egypt, but also that among all the gentiles there was a retrogression."
