If you haven’t read philosophy before, it can be daunting. Doing it with an instructor helps. A good instructor or lecturer can give you context, guide you to what is important, help you ask the right questions, even acknowledge the difficulty of what you are reading.
If you don’t have that but still want to give it a try, I recommend this list by Nigel Warburton. Some of them are general, and some focus on specific fields of philosophy. They all sound good. Read the list: Warburton tells you what each book is about and why you want to read it.
I suspect by the time you finish the article, you’ll want to go out and get one of those books.
