Exactly! And Peterson and Harris have known to have their fair share of differences in the past actually.
I’m sure they’ll elaborate on what they were discussing above. Bret Weinstein is also a fascinating individual with a wide range of knowledge.
Peter Singer is mainly known for his contributions to the Animal Liberation movement in the States. I however recommend his collection of essays, Ethics in the Real World. Honestly, such a phenomenal piece of work. His essay Famine, Affluence, & Morality is also great. Recently Bill Gates wrote a forward to it. He is definitely in the top 10 of most influential philosophers alive.
A. C. Grayling writes more philosophical works. He has an encyclopedia almost where he defines different terms and worldviews, which is a massive volume (400–600 pages). His more readable work is on Religion: The God Argument: The Case against Religion and for Humanism. I recommend that one. But he’s written like 30 books or something. A very well respected public intellectual based in London.
