This strikes me as the most hilarious question, given that I’m a philosopher. Philosophy is all about respectful disagreement, and learning from disagreement. No decent philosopher simply parrots some other philosopher, so there must be disagreements somewhere in every case. I disagree less with J.S. Mill than with any other major philosopher, but I still disagree with Mill a good deal. Aristotle is insightful on some matters, not so insightful on others. As for Plato, Kant, Bentham, Sidgwick, and Rawls, my disagreements are larger, but still compatible with thinking that in some very major ways they were on the right track. I would not say that about Lord Devlin or James Fitzjames Stephen, but I still teach both, in order to learn from their arguments. If I didn’t disagree with a philosopher it would hardly be worth engaging with him or her, because there would be nothing to learn.

Even though I’m not a utilitarian, and so I tend to disagree with Singer in terms of the general framework, this book literally changed my life. I read it many years ago, in the 1990s, when I was in Knoxville, Tennessee.

I’ve read Cheney’s and Bush’s autobiographies. Books by Sarah Palin and Anne Coulter. I read articles on Breitbart.

We should engage with these texts. I disagree with them, and I argue back against them, but I don’t think that means they shouldn’t be read and thought about.

Wasting time reading blogs, magazines, newspapers. They have their place but they can become an addiction. And the real ways to gain understanding about issues are reading books and traveling.
