An interesting perspective. I think it's very close to the spirit which philosophy - if any - works for each one of us. Amorality works for this writer and sharing his views is satisfying to him. But I wouldn't begrudge someone else their morality, religion, or agnosticism. What resonates for us, works for us, I think, is for each one of us to decide.
Yeah, I'm roughly in alignment with your reaction. I think we use reason and logic to confirm the "conclusions" we've already come to. But occasionally thinking through why I do the things I do does help me reexamine and change my mind or actions. So it can't be all bad.
