Armchair Opinions is a blog where qualified philosophers – the Armchair Philosophers – answer questions asked by the public. Here, on the podcast, we take a closer look at some of those answers. Hosted by Alex Impey and Armchair Philosophers Carl Messenger and James Brown.
You can watch our recording sessions on our YouTube channel, join the conversation yourself on our subreddit, and even listen to the songs we mention (plus a few others) on our Spotify playlist.
If you have a question for the Armchair Philosophers, don’t hesitate to get in touch. You can find us on Twitter @armchair_o or fill in this form.
