Natural theology and natural law › Reading the primary text

Read I q.2 in full, including the objections and replies, before reducing the Five Ways to slogans. I q.13 a.5 supplies the account of analogy. For law, read I-II qq.90-91 and q.94, then q.96 a.4 for the qualifications concerning unjust law. This sequence distinguishes reason's proposed starting points from the conclusions it still has to earn.
