Etymology: This noun is a plural form derived from the base word "irrationalism," which itself entered English in the 19th century. The root "irrational" combines the Latin prefix "in-" (meaning "not") with "rationalis," from "ratio," meaning "reason" or "calculation." Thus, it literally denotes something "not rational" or "beyond reason." The suffix "-ism" was added to signify a system, doctrine, or belief centered on this quality. Originally, the term "irrationalism" arose in philosophical and psychological contexts to describe worldviews or attitudes that reject or undermine reason and logical thinking. It was often contrasted with rationalism, a dominant intellectual movement emphasizing reason as the chief source of knowledge. The plural form simply refers to multiple instances or varieties of such doctrines or attitudes. The shift from describing the abstract quality of being irrational to naming specific doctrines reflected the 19th-century intellectual climate, when thinkers sought to categorize and critique emerging ideas that challenged Enlightenment rationality. Over time, the plural form came to be used more broadly, encompassing diverse movements or moments characterized by rejection of reason, whether in philosophy, art, or social theory. In sum, the word traces back to Latin roots about reason and its absence, with a 19th-century coinage marking a conceptual response to shifting intellectual currents. The plural form expands the scope to multiple manifestations of these anti-rational tendencies.
