Definition
Deism is the belief in a God who created the universe but doesn't interfere with it. Deists believe that God is like a watchmaker who set the universe in motion and then stepped back. They rely on reason and observation of the natural world to understand God, rather than relying on religious texts or revelation. Deism contrasts with theism, which involves a more active and interventionist God. Think of deism as a hands-off approach to divinity; God created, but doesn't meddle.
