Summary

Jansenist theologian and moralist who co-authored the Port-Royal Logic with Antoine Arnauld and analyzed the role of self-love (amour-propre) in social morality.

Core Contribution

Co-authored the Port-Royal Logic — the most widely used logic textbook in Europe for over a century, introducing probability reasoning. Analyzed how self-interest, when channeled properly, can serve social order — anticipating Mandeville and Smith.

Key Spikes & Highlights

  • His analysis of self-love: civil society is held together not by charity but by enlightened self-interest — a proto-liberal insight that charity is dispensable if commerce and interest align.
  • The Port-Royal Logic was revolutionary for treating rhetoric and probability alongside syllogistic — breaking logic's monopoly on formal reasoning.
