One of this thinker's works describes things that do not themselves change, but have change "annexed to them", as "aeviternal". He defined a law as "an ordinance of reason for the common good" and considered the difference between a "subsistent" and a "substance" in a work whose analysis of the concept of murder in self-defense gave rise to the principle of (*) double effect. Truths that surpass the capability of reason are covered in the fourth section of a book by this man that was supposedly commissioned by Raymond of Peñafort. He often refers to "the Jurist", "the Commentator", and "the Philosopher", or Ulpian, Averroes, and Aristotle, in a work that introduced the quinque viae, five proofs of God's existence. For 10 points, name this Dominican friar who wrote Summa Contra Gentiles and Summa Theologica.
