The beginning should be to recognize that there is a difference between believe and knowledge. And that one must start to differentiate there cleanly. This mental prison in which we move, or move, is almost 90% believing. The belief in the legitimacy of a state, or laws, or the belief in the time, or the belief in theories. People live by this belief and I'm not talking about religion here. There are little lies to hide big, religions, 9/11, are little lies. The earth is not a ball, is a big lie, because a huge belief in the construct depends on it, namely world view, and self-image. But basically you should start to realize that you have to believe things you read or hear. And you can only experience knowledge yourself.
I am glad that there are more, not ball believers here.
