Thomas Aquinas,
Summa Theologiae — The Nature and Extent of Sacred Doctrine
“ Article 2 - Whether it is a science? Article 3 - Whether it is one or many? Article 4 - Whether it is speculative or practical? Article 5 - How it is compared with other sciences? Article 6 - Whether it is the same as wisdom? Article 7 - Whether God is its subject-matter? ”
