“Almost all our suffering is the product of our thoughts. We spend nearly every moment of our lives lost in thought, and hostage to the character of those thoughts. You can break this spell, but it takes training just like it takes training to defend yourself against a physical assault.”

American neuroscientist, philosopher, author, and podcast host

Samuel Benjamin Harris is an American neuroscientist, philosopher, author, and podcast host. He became widely known for his criticism of religion and is often grouped with Richard Dawkins, Christopher Hitchens, and Daniel Dennett as one of the "Four Horsemen" of New Atheism. His work ranges across rationality, ethics, free will, determinism, neuroscience, meditation, psychedelics, philosophy of mind, politics, terrorism, and artificial intelligence. Much of his public writing and speaking returns to questions about how people think, what they believe, and how reason should shape public life.
