Common Logical Fallacies Explained in Latin
When we talk about bad arguments, manipulation, or faulty reasoning, Latin appears just as often—though usually in a more confrontational way. Terms like ad hominem, post hoc, or non sequitur
Latin is unique among European languages in the length and continuity of its intellectual tradition. For over two thousand years, it served as the shared language of learning, scholarship, and religious life, connecting the ancient world with the medieval and early modern periods. Few languages have maintained such a central role across so many centuries and disciplines.
One of the most enduring aspects of this tradition is Latin’s role in Christianity. As Christianity spread throughout the Roman world, Latin became the primary language of Western Christian thought, theology, and worship. The writings of the Church Fathers, biblical commentaries, theological treatises, and ecclesiastical law were composed in Latin, shaping the intellectual foundations of Western Christianity. For centuries, Latin remained the official language of the Catholic Church, used in liturgy, prayer, and education.
From the Latin Bible and the prayers of the Mass to medieval theology and devotional texts, Latin functioned as a language of continuity and transmission. It allowed ideas, doctrines, and spiritual practices to be preserved and shared across regions and generations, forming a living tradition rather than a closed historical archive.
Studying Latin today means entering this tradition directly. It allows learners to understand Christian texts, prayers, and theological concepts in the language in which they were originally formulated, gaining greater clarity and depth of understanding.
This path begins with Latin I: First Steps, the introductory course for absolute beginners, which provides a solid foundation in reading and understanding Latin through a structured, reading-based approach using Lingua Latina per se illustrata: Familia Romana. Building on this foundation, Rosarium: Latin Course focuses specifically on the Latin of Christian prayer and devotion, guiding students through the language of the Rosary and related liturgical texts.
Together, these courses offer a coherent path into a two-millennia intellectual and spiritual tradition—one in which Latin remains not only a historical language, but a meaningful and living medium of thought, faith, and learning.

When we talk about logic and argumentation, we often use Latin without noticing. Expressions like ergō, ā priori, or prima facie appear in philosophy, law, academic writing, and even everyday
