The more you know that is credible the less likely you are STUPID!

There is only but one way to know and that direction is any way that leads to intelligence and away from ignorance!
Being intelligent is when you can say something that can not be disputed because it is absolutely true! It is analytical and it is rational.

For example, my intelligence is beyond reproach. I said that prophets are racially different. That is a revelation that no one or book writer or theologian universities have ever said that prophets are racially different.
Consequentially, that means that the prophet you claim must be the same race as you are is absolutely true and can not be disputed.
