Sam Harris is an American author, neuroscientist, and philosopher known for his critical views on religion and his advocacy for science-based reasoning. With a Ph.D. in cognitive neuroscience from UCLA and a background in philosophy, Harris bridges the gap between rigorous scientific inquiry and deep philosophical questions about human consciousness, ethics, and spirituality. He gained widespread recognition with his 2004 book The End of Faith, which critiques organized religion while advocating for secularism.

Harris has since authored several bestsellers including Letter to a Christian Nation, The Moral Landscape, and Free Will. In addition to his written work, he hosts the popular podcast Making Sense, where he engages in thought-provoking discussions with leading intellectuals across various fields. An advocate for meditation and mindfulness as valuable tools for personal development, Sam Harris also founded the Waking Up app to offer guided meditative practices rooted in both scientific understanding and contemplative traditions.

2. “The only thing that permits human beings to collaborate with one another in a truly open-ended way is their willingness to have their beliefs modified by new facts. Only openness to evidence and argument will secure a common world for us.”
3. “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.”
