If our well-being depends upon the interaction between events in our brains and events in the world, and there are better and worse ways to secure it, then some cultures will tend to produce lives that are more worth living than others; some political persuasions will be more enlightened than others; and some world views will be mistaken in ways that cause needless human misery.

If faith is what you have to go on, if faith is the link between your beliefs and the world at large, your beliefs are very likely to be wrong. Beliefs can be right or wrong. If you believe you can fly, that belief is only true if indeed you can fly. Somebody who thinks he can fly, and is wrong about it, will eventually discover there's a problem with his view of the world.

Spiritual life can certainly follow the pattern one sees in the fake martial arts, with most teachers making nebulous and magical claims that never get tested, while their students derange themselves with weird ideas, empty rituals, and other affectations.

If you are perpetually angry, depressed, confused, and unloving, or your attention is elsewhere, it won't matter how successful you become or who is in your life - you won't enjoy any of it.

Faith does not offer a strong link between our beliefs and actual states of the world.

Unlike statements of fact, which require no further work on our part, lies must be continually protected from collisions with reality.
