"A man has free choice to the extent that he is rational"
About this Quote
The subtext is a quiet rebuke to two temptations: fatalism (“I couldn’t help it”) and libertinism (“I did it because I wanted to”). Aquinas refuses both. He treats irrationality not as edgy spontaneity but as a form of bondage: to impulse, to confusion, to sin, to misinformation (avant la lettre). That’s why the line lands with such force: it turns freedom into a diagnostic. If you feel most “free” when you’re most unthinking, Aquinas would say you’re confusing volatility for agency.
Context matters. Aquinas is stitching Aristotle’s psychology to Christian theology, building a system where the will aims at the good, but reason is what identifies the good in concrete situations. Rationality isn’t just IQ; it includes practical wisdom, moral formation, and the capacity to deliberate. The intent is ultimately pastoral and political: a society that wants free citizens must cultivate reason, not just remove restraints.
