Yes and No

work by Abelard
Also known as: “Sic et non”

Quick Summary

The work Sic et non (Yes and No) by Peter Abelard is a compilation of theological questions with citations from authorities on both sides of each issue. Abelard, a 12th-century French theologian and philosopher, used this method to teach students how to reconcile apparent contradictions and reach correct solutions through logical reasoning and careful analysis of language.12

Abelard's approach was innovative, employing dialectics to explore complex theological topics. This method contributed to the development of Scholasticism. He also engaged with the philosophical problem of universals, proposing a view distinct from both nominalism and realism. His work, though influential, also drew criticism and condemnation during his lifetime.12
