Abstract

This chapter focuses on one of the common fallacies in Western philosophy: chronological snobbery (CS). First described by the Christian academic Owen Barfield in the 1920s and later popularized by his friend and colleague C.S. Lewis, the fallacy of CS presupposes that cultural, philosophical, or scientific ideas from later time periods are necessarily superior to those from earlier ages. Grounded on the Enlightenment's concept of “progress”, this informal fallacy stems from the assumption that the ever‐increasing amount of knowledge in society naturally and perpetually replaces all outdated, disproven ideas with updated, better‐justified beliefs, therefore making old ideas incorrect or irrelevant simply because they are old. Essentially the opposite of the appeal to ancient authority, CS relates to guilt by association, hasty generalization, and poisoning the well fallacies whenever it references unrelated false beliefs held by individuals from the originating time period.
