Or I mean can we know what they are thinking about?

So, in principle, we can read the information of what their thoughts are about?

So that we can easily communicate with deaf and dumb person?

One day,might it be able to read clearly every sentence in the brain by machine?

If we define God is Supreme Form of Goodness and Evil is Supreme Form of Badness.Then how can we deduce that God creates (causes) all things

I know that Supreme Form must be Real and Perfect,but I do not understand why it must be Good .Follow Plato the Supreme Form must be Real and supreme Perfect therefore must be supreme Good.What make Plato thinks that if he not consider the Reality means Goodness?

So following Plato( maybe in Philosophy in general?) all real things are good.?

If the theory of Plato is wrong, why does it influence so much in Western Philosophy?
Is there any relation between goodness and the moral behavior or ethic?
