A belief is a lever that, once pulled, moves almost everything in a person’s life. Are you a scientist? A liberal? A racist? These are merely species of belief in action. Your beliefs define your vision of the world; they dictate your behavior; they determine your emotional responses to other human beings. If you doubt this, consider how your experience would suddenly change if you came to believe one of the following propositions:

1. You have only two weeks to live.
2. You've just won the lottery prize of one hundred million dollars.
3. Aliens have implanted a receiver in your skull and are manipulating your thoughts.

These are mere words- until you believe them. once believed, they become part of the very apparatus of your mind, determining your desires, fears, expectations, and subsequent behavior.

In adaptive terms, belief has been extraordinarily useful. It is, after all, by believing various propositions about the world that we predict events and consider the likely consequences of our actions. Beliefs are principles of action: whatever they may be at the level of the brain, they are processes by which our understanding (and misunderstanding) of the world is represented and made available to guide our behavior.

What are our beliefs designed for? They’re the guiding force to tell us what will lead to pain and what will lead to pleasure.

Beliefs are choices. First you choose your beliefs. Then your beliefs affect your choices.

A belief is what you know to be true because experience has made it evident to you. If you want to change your life, change your beliefs. If you want to change your beliefs, go out and have experiences that make them real to you. Not the opposite way around.

I have been vehemently accused by people who didn’t understand me of not believing in anything. I don’t believe in anything. This is not a statement of existential hopelessness for which you should light a candle for me at night. It’s a strategy for not getting bogged down in some weird trip. After all, what is the basis for believing anything? I mean, you have to understand: You’re a monkey. In some kind of a biological situation where everything has been evolved to serve the economy of survival — this is not a philosophy course. So belief is a curious reaction to the present at hand. It isn’t to be believed, it’s to be dealt with — experienced and modeled.

Beliefs create reality

Ninety percent of what we believe has nothing to do with the process of thought, but comes instead from the four sources of family inheritance, individual temperament, national culture, and economic self-interest; and while we cannot wholly cast off these shackles, we should at least recognize their cramping and distorting influence upon the free process of thought.

All beliefs about matters of fact or real existence are derived merely from something that is present to the memory or senses, and a customary association of that with some other thing.

As if one believed anything by instinct! One believes things because one has been conditioned to believe them. Finding bad reasons for what one believes for other bad reasons — that's philosophy. People believe in God because they've been conditioned to believe in God.

Every mental act is composed of doubt and belief,
but it is belief that is the positive, it is belief
that sustains thought and holds the world together.

Belief means not wanting to know what is true.

The problem I want to talk to you about tonight is the problem of belief. What does it mean to believe? We use this word all the time, and I think behind it lurk some really extraordinary taboos and confusions. What I want to argue tonight is that how we talk about belief- how we fail to criticize or criticize the beliefs of others, has more importance to us personally, more consequence to us personally and to civilization than perhaps anything else that is in our power to influence.

All behavior is driven by belief, so before we address how to learn, we must first address the underlying beliefs we hold about what is possible.
