Thomas Smith, host of the podcast Atheistically Speaking, had me on to talk about moral philosophy and Sam Harris’s The Moral Landscape. Previous guests of the program include philosopher Massimo Pigliucci, a critic of Harris.
Thomas is a supporter of Harris’s scientific theory of morality. He and I had a friendly and fruitful discussion that spanned two, one-hour episodes. Both are available for free download. Read on for an outline of each episode, plus some related links.
- Sam Harris’s main argument & my winning essay’s critique
- Competing ethical theories: consequentialism, deontology, and virtue ethics
- My response to this quote from The Moral Landscape about moral philosophy:
Many of my critics fault me for not engaging more directly with the academic literature on moral philosophy…I am convinced that every appearance of terms like “metaethics,” “deontology,” “noncognitivism,” “antirealism,” “emotivism,” etc., directly increases the amount of boredom in the universe. My goal…in writing this book is to start a conversation that a wider audience can engage with and find helpful. Few things would make this goal harder to achieve than for me to speak and write like an academic philosopher. Of course, some discussion of philosophy will be unavoidable, but my approach is to generally make an end run around many of the views and conceptual distinctions that make academic discussions of human values so inaccessible. While this is guaranteed to annoy a few people, the professional philosophers I’ve consulted seem to understand and support what I am doing.

- My response to this quote from Sam Harris:
The whole point of The Moral Landscape was to argue for the existence of moral truths—and to insist that they are every bit as real as the truths of physics. If readers want to concede that point without calling the acquisition of such truths a “science,” that’s a semantic choice that has no bearing on my argument.
I’d like to thank Thomas for having me on his show. I hope to join him again soon to talk more about philosophy.
