According to the SelectSmart.com ethical philosophy quiz, these are my three closest matches (I think #1 is automatically set to 100%):
1. Thomas Aquinas 100%
2. Augustine 90%
3. Plato 88%
That Aristotle was fifth at 78% wasn't surprising either. That Bentham was fourth at 87%, however, is a sign of the fallibility of internet quizzes.
