Should Writers Describe What is True?

I thought -- I will write a story about what people are really like. We imagine we move according to cause and effect, whereas in reality we are particles with velocity but no location. Or if we have location we have no velocity. We can be in two places at once. If we are together and go apart, then there is energy; if we are static, there is not. These are the conditions of being human. Our minds and our stories find it difficult to grasp this. But a writer should try to describe what is true.
