The promise of spiritual life — indeed, the very thing that makes it “spiritual” in the sense I invoke throughout this book — is that there are truth… - Sam Harris

What we need to become happier and to make the world a better place is not more pious illusions but a clearer understanding of the way things are.

Either consciousness is epiphenomenal or it’s outside a physical system but somehow playing a role in physics. That’s a more traditional, dualist possibility. Or there’s a third possibility: Consciousness is somehow built in at the fundamental level of physics.

There had been ample warning that a storm “of biblical proportions” would strike New Orleans, and the human response to the ensuing disaster was tragically inept. But it was inept only by the light of science. Religion offered no basis for a response at all. Advance warning of Katrina’s path was wrested from mute Nature by meteorological calculations and satellite imagery. God told no one of his plans. Had the residents of New Orleans been content to rely on the beneficence of God, they wouldn’t have known that a killer hurricane was bearing down upon them until they felt the first gusts of wind on their faces. And yet, as will come as no surprise to you, a poll conducted by The Washington Post found that 80 percent of Katrina’s survivors claim that the event has only strengthened their faith in God.

You don't get anything worth getting by pretending to know things you don’t know.
