📺Bonus Episode: What (12) Grad Students Wish They’d Known About Doing a PhD This is the final episode of the First Season of the Philosopher’s Nest. Lewis and I have so enjoyed interviewing wonderful philosophy grad students. We’ll return in October❤️ open.spotify.com/episode/64pJtR…
📺New episode! We spoke with Elliot Thornley (Oxford) about population ethics, global priorities research and monograph vs. integrated paper theses. This episode was sponsored by Effective Thesis (@EffectiveThesis). After you listen, check them out! open.spotify.com/episode/1HJK7R…
