Friends and Fans — I have retired from my work as a public intellectual, so Philosophy in Action is on indefinite hiatus. Please check out the voluminous archive of free podcasts, as well as the premium audio content still available for sale. My two books — Responsibility & Luck: A Defense of Praise and Blame and Explore Atlas Shrugged — are available for purchase too. Best wishes! — Diana Brickell (Hsieh)

Each week, I choose four of the most popular and interesting questions currently from this Question Queue to answer in the next Sunday Q&A Radio Show. Please use the buttons or widget below to review and vote for questions in the queue and submit your own questions.

I'm perfectly willing to be bribed to answer a question of particular interest to you. So if you're a regular or potential contributor to Philosophy in Action's Tip Jar, I can answer your desired question as soon as possible. (The question must already be in the queue, so if you've not done so already, submit it. Just e-mail me at to make arrangements.

Philosophy in Action Radio focuses on the application of rational principles to real life. So I prefer questions on some concrete real-life problem, as opposed to merely theoretical or political questions.

I review and edit all questions before they're posted. (Alas, IdeaInformer doesn't display any kind of confirmation page when you submit a question.)
