Thanks again, everybody!
And, yeah, Tyrone, I think that's really important for exactly the reason you give—and for other reasons as well. Here, this is from my introduction to the book:
------
The questions I ask will sometimes be ambiguous. They will sometimes be frustrating, or leading. Some will have easy answers that are hard to explain, where some will be difficult to even get a grasp on. This is all on purpose. This isn’t a class—there’s not supposed to be a right answer that you’re trying to get—and philosophically valuable questions can be valuable because of what you have to go through to get them rather than because the answer is itself valuable. Keep in mind that in writing these questions, I am not always playing nice, or even playing fair. I am giving you a challenge and a direction for thought and discovery.
The “answers” I provide here are often not answers at all. I think that’s appropriate: these issues wouldn’t be philosophical issues at all if there were answers, especially answers that would fit into a single page (or a whole book). The perspectives included are not necessarily chosen because I think they are right, or because I think you’ll find them convincing, although that is certainly sometimes the case. But they are chosen primarily because they’re significant, plausible, and challenging—in short, worth working with and working through.
