About this source
What it is
This is an English translation of part of the Summa Theologica, the central theological work of Thomas Aquinas, covering questions on human action and ethics. The translation was made by Fathers of the English Dominican Province and published by Benziger Brothers; this electronic text was prepared later by volunteer transcribers, not by Aquinas himself.
Why it matters
The Summa Theologica is one of the most influential works of Christian theology and philosophy, shaping Catholic doctrine for centuries. This section addresses deep questions about good, evil, and human choice, showing Aquinas's systematic method of posing questions and reasoning through answers.
Look closer
- Why does Aquinas organize his writing as questions and articles rather than a flowing narrative?
- What does the dedication to the Virgin Mary tell us about the purpose of the work?
- How might translation and later editing change the way we read a medieval text today?
