I am your Grandpops age with a BA in Philosophy. I've read almost everything she wrote. If you want to know what you'll be facing in a philosophy course in college, I urge you to find a copy of The Objectivist Volume 9 Number 8 August 1970 in which Ayn Rand wrote an article titled "The Comprachicos".

With thought of "know your enemy", I would tentatively approve studying Philosophy. You'll hate parts of it. Are you doing it for the degree, or the fun? If all you want is the learning, minor in Philosophy or just pick and choose your courses. It's also very important to find a professor that you trust, early on - not necessarily in the Phil. Dept, but it helps. Such a person can tell you "he's a moron, read this" or "take it twice". And, degree in hand and knowledge in brain, what are the things you want to do then?
.....says the History major who could have graduated with 5 B.A.'s but didn't want to take the stupid entry-level classes. so also says the person with a partial Masters' Classical Antiquities [ancient languages, art, architecture, literature & anything else that sounded interesting] degree, who got tired of the administrations' excretions.

Great comments already. I would add that Ayn Rand's logical presentation of her ideas in the context of the social, political, economic events of the day are insightful and so well thought-out. These are the volumes (TON and TO) in which Rand and Peikoff first published a lot of what was later repackaged in book form (Introduction to Objectivist Epistemology, The Analytic-Synthetic Dichotomy, and more). It's certainly diving right in. For a lighter dive, I like For the New Intellectual or Capitalism: The Unknown Ideal.

Hi. Some of the essays from The Objectivist Newsletter are reprinted in other Ayn Rand books which I have read. Should you take a philosophy course? Absolutely! How did Ayn Rand develop her ideas? How do they compare to the ideas of Descartes or Thomas Hobbs, or John Locke? Who was Seneca, Plato or Hippocrates? How have ideas changed through the centuries? What is dialectical reasoning? If knowing the answers to questions like these is important to you --get thee to a class! ;)
