Discussion of Scientific Postmodernism Mention postmodernism in casual conversations, as I have done, and you will probably get one or more of the following responses. Your listener may have heard of a transitory "postmodern" movement such as "postmodern art" and think that you mean that. They may have heard of a "modern" movement such as "modern art" and think that you mean a successor movement. They may reason that since modern often means contemporary and post often means after, postmodern means after contemporary, but when is that? They may simply be baffled by your use of an unfamiliar term. Postmodernism means understanding that all of history has three successive periods--premodern, modern, and post- modern--each of which is distinguished by its unique zeitgeist (spirit of the age), and understanding that humankind is now in the third, postmodern, period. The premodern thesis, modern antithesis, and postmodern synthesis are the unique sources of these unique zeitgeists. Both the zeitgeist concept and the dialectic (thesis-antithesis-synthesis) concept come from Georg W. F. Hegel. I call this understanding "Zeitgeist Postmodernism," it is the foundation on which Scientific Postmodernism is built. Upon first encountering it, the term "Scientific Postmodernism" might be confusing since it was prior to the postmodern period (during the modern era) when the scientific method was discovered and first put to use. I take the term "Scientific" from the phrase "queen of the sciences," where "sciences" mean "fields of knowledge." According to the original monotheism hypothesis, religion was the queen of the sciences and there was an ideational emphasis as opposed to sensate emphasis at the dawn of the premodern age. The Copernican Revolution, dateable to Copernicus's publication of On the Revolutions of the Heavenly Spheres in 1543, made mathematics queen of the sciences and brought about a senate emphasis at the dawn of the modern age. A foundational crisis in mathematics of similar magnitude, dateable to Kurt Godel's publication of his incomplete- ness theorems in 1931 and 1932, deposed queen mathematics and restored religion and similarly overthrew the senate emphasis and restored an ideational emphasis at the dawn of the postmodern age. The concept of alternating idea- tional and senate periods comes from Pitirim Sorokin. I call this enhanced understanding of Zeitgeist Postmodernism "Scientific Postmodernism." © 2025 postmode
