On this page, you’ll find agnostic/atheist philosophers, who present philosophical reasons both against theism and for atheism. The most prominent of these are the Problems of Evil and Hiddenness, with the Kalam Cosmological Argument rounding out the top 3 (that I’ve seen).
Joe Schmid, aka Majesty of Reason is (as of 2023) a PhD student in philosophy at Princeton University, who has done many in-depth interviews and discussions of why theistic arguments for the existence of any god, and particularly the Christian god, don’t hold water. He’s also published 2 books, which are linked on his website. This playlist contains ALL of his videos, but he breaks them up into smaller playlists on his channel, too.
Alex O’Connor, formerly the Cosmic Skeptic, is an Englishman, who (as of 2023) has completed a degree in Philosophy & Religion at St. John’s College of Oxford University in England. He’s been featured on the BBC, has engaged in debates with numerous prominent theologians and apologists online and in person, written extensively, etc. His channel is one of the largest atheist channels on YouTube
Graham Oppy is a Professor of Philosophy at Monash University in Australia, who has debated and discussed all the philosophical questions for and against the existence of god(s). He doesn’t have a YouTube channel, so I’ve compiled a small selection of his videos in this playlist. He’s published numerous scholarly articles and books, all of which are listed on his university page link.
As mentioned on the main page about atheism, I mentioned Scott Clifton and his channel Theoretical Bullshit. He’s an amateur philosopher and quite a good one. He almost never makes YouTube videos on atheism any more, but his past ones are enjoyable. He’s soft-spoken, precise in his speaking and thinking, respectful, yet hard-hitting. Well worth listening to IMO. I don’t know why it says “Video Unavailable” in the preview, but if you follow it to YouTube, the playlist is available.
Rationality Rules offers a mix of serious philosophy and knocking low-hanging fruit out of the park in hilarious take-downs, so he’ll be listed a couple of times in my lists.
Of course, there’s the inimitable Christopher Hitchens.
There’s more to come, but in the meantime check out other great atheist creators here:
