Materiality: Is It Real?
... our material reality is the result of man’s practical nature. Physics is concerned with physical phenomena for which it is necessary to have practical explanations. Every physical substance has mass, or its essential existence . Its mass is what is pushed, pulled, spun, or just allowed to lie there, ...
