Dialectical materialism accepts that the natural world changes. New qualitiews of being will come to light with each change. . As Z. A. Jordan noted, "Engels made constant use of the metaphysical insight that the higher level of existence emerges from and has its roots in the lower; that the higher level constitutes a new order of being with its irreducible laws; and that this process of evolutionary advance is governed by laws of development which reflect basic properties of 'matter in motion as a whole'."
