1225 – 1274Thomas Aquinas
Medieval theologian and philosopher who synthesized Aristotelian reason with Christian doctrine into Scholastic method.
About Thomas Aquinas
When young Thomas joined the new Dominican order against his noble family's wishes, they kidnapped him and locked him in a castle for a year. He spent the time memorizing Scripture and studying Aristotle. They called him the 'Dumb Ox' because he was large, quiet, and slow to speak, but when he did speak, his arguments were devastating. Thomas faced a crisis: the rediscovery of Aristotle's complete works through Arabic translations threatened to split faith from reason. Many wanted to ban Aristotle; Thomas chose instead to baptize him. His Summa Theologiae, meant as a 'brief' textbook for beginners, became the most comprehensive synthesis of Christian thought ever written: thousands of articles, each beginning with objections he stated more forcefully than his opponents could, then systematically resolved. He wrote on God's existence, the nature of the soul, law, virtue, and the proper ordering of society.

Example conversation with Aquinas
Topic: Faith and Reason Working Together
You
A lot of people today think faith and reason are opposites. How would you respond to that?Aquinas
I would say they are confusing a false opposition for a real one. Let us make a distinction. Reason operates by natural light, examining what we can observe and deduce. Faith receives what God has revealed, truths that exceed our natural capacity. But truth cannot contradict truth. If a conclusion of reason genuinely conflicts with a teaching of faith, then either the reasoning contains an error or the teaching has been misunderstood. I spent my life showing that Aristotle, a pagan philosopher, arrived at truths that harmonize beautifully with Christian doctrine.You
But was it not controversial to rely so heavily on Aristotle? Some people in your time wanted his works banned.Aquinas
Indeed, and I understand their concern. When Aristotle was rediscovered through Arabic translations by scholars such as Averroes and Avicenna, many feared his philosophy would undermine Christian teaching. Some at the University of Paris sought to prohibit his works entirely. But I believed this was a mistake born of fear rather than understanding. If Aristotle had discovered genuine truths about nature, causality, and ethics, then those truths belong to God as their author, regardless of who first articulated them. We should not reject truth because of its source.You
How do you actually use this method when you are working through a difficult question?Aquinas
I begin by stating the objections as fairly and forcefully as I can, often stronger than my opponents would state them themselves. Then I bring forward an authority that points toward the truth, the sed contra. Finally, in my own response, the respondeo, I work through the matter by making careful distinctions. Most apparent contradictions dissolve when you define your terms precisely. For instance, when someone says reason opposes faith, I ask: what do you mean by reason? What do you mean by faith? Once we distinguish their proper objects and methods, the opposition vanishes.Key ideas
- •Truth is one; faith and reason cooperate.
- •Distinctions are tools for understanding.
- •Natural law grounds moral reasoning.
How to apply
- •Structure inquiry with objections and replies.
- •Clarify terms before arguing conclusions.
- •Derive practical judgments from first principles.
