Hi there! Good on you for recognizing the crucially important role of philosophy—it really is the handmaiden of theology (and also just really interesting in itself!) I have a BA in philosophy from a major secular school, and though I’m many many years removed from that program (late 90’s), I’m so utterly grateful that I studied it! It’s been a lifetime of rewards, imho.
So, on to your categories. First, I have to admit that listening to Jay Budziszewski speak as a guest-lecturer when I was in undergrad was a central impetus behind me pursuing a philosophy degree.
Philosophy of Natural Law:
Anything by Jay Budziszewski, he’s so good in this area. Robert George and Frank Beckwith are great too.
Logic
There are many good texts. Two in particular that are Catholic-friendly (i.e., not hung up in contemporary analytical problems of philosophy) and that I got a lot out of are Norman Geisler (
Come, Let Us Reason) as a very beginner text and Henry Veatch for more advanced stuff (see his
Two Logics).
Ethics
You should start with Aristotle’s
Nicomachean Ethics It’s very approachable—you’ll probably be shocked to learn just how easy to follow and chock full of common-sense that text is. Frank Beckwith also has good stuff in ethics. And Aquinas’ portions in the ST concerned with virtue are excellent! If you want something contemporary, check out Linda Zagzebski—her virtue writings are top notch!
Metaphysics
So much good Thomistic stuff out there these days that explores the topic in a sophisticated way. John Wippel has a great text. Edward Feser also has a lot of good stuff. I’d start with them.
Ancient Philosophy
Frederick Copleston had a good series on the history of philosophy, particularly good (so I think) was his volume on ancient philosophy. After a survey book like that, you would do well to read the primary sources—Plato’s dialogues and Aristotle’s writings, mostly. All of the dialogues that deal with the “last days of Socrates” (Euthyphro, Crito…) are very digestible even for a beginner. So is Plato’s
Symposium. And for Aristotle, start with the
NE that I mentioned above.
Medieval Phil and Modern Phil
Also, continue with Copleston for a good overview. A very good text here is Etienne Gilson’s small volume
God and Philosophy. it does a great job at offering a sketch of major differences between ancient, medieval and modern philosophy, comparisons and contrasts in important areas. Also, if you’d like something contemporary, I’d check out Eleonore Stump. She’s Thomistic and fantastically clear.
I’m so excited for you! You have a long journey ahead but it’ll be so rewarding. Keep us posted on your explorations, if you feel so inclined.
