Apply your own common sense whether 'unified field of total natural law' is pure science or pseudo-science. Even in physical level of existence you will get nothing but unity of everything. Here is an example: Consider your body. What is your body made up of? Various organs. What are various organs made up of? Tissue. What are tissue made up of? Cell. Cell is the fundamental structure of every living entity here on this planet. Do you want to go more deeper than cell? You can go. You will get nothing but "UNITY." Even in mental level, the mind stuff of every living entity is made up of same thing. You can further go deep by analyzing Einstein Theory of Energy, E = MC^2. From this equation you can calculate Mass, M = E/C^2. Whatever the mass is, it is nothing but energy. Cell, in fact, if you go deeper then you will find it is merely a vibration. Einstein Theory of Relativity also explains that this world is merely a phenomenon. Motion exist by virtue of other objects which are at rest! Therefore, unified field of total natural law is that field from which all diversity appears.
