Thomas Aquinas's Third Argument

A Level: AQA • Edexcel • OCR • WJEC

GCSE: Edexcel A • Edexcel B

A detailed investigation into Thomas Aquinas's third presentation of the cosmological argument, including how it works, and why it's convincing. This lesson provides a brief biography of Thomas Aquinas, and covers the text of Summa Theologica. This includes how the problem of infinite regress can only be avoided by assuming the existence of a necessary being that created the universe, which supports the argument for the existence of God.
