However, I did read "The Prince" and I think there's a lot most can learn from it. While I find the majority of the book reprehensible, there are many powerful people in our society that seem to think of it as a bible / instruction manual. Given the fact that such ideas still play a significant role in our society; I feel it is worthwhile to learn about them.
Edit: Thanks for the clarification.
If you've lumped "The Art of War" into the same category in your mind as Ayn Rand's writings, I suggest you to read it. You may find yourself pleasantly surprised. Aside from being both commonly cited as influential (in greater or lesser unfortunate ways), there's really about zero similarity between the two.
I definitely mean in the greater of unfortunate ways. That there's zero similarity is irrelevant, they keep showing up in the same places. They're not brothers, they're friends.
