Abstract
Contemporary physicists, in creating theories adequate to nature's patterns of movement and development, speak the language of dialectics whether willingly or unwillingly. Even those whose personal outlook is at variance with dialectical philosophy acknowledge this in their own way. Thus Heisenberg states that inquiry into the foundations of the quantum theory, especially as carried out by Bohr, has features reminiscent of Hegelian philosophy. And, to quote Pauli, "dialectics is that mutual game of two opponents which is typical of the Copenhagen interpretation of quantum mechanics." Bohr himself, while discussing the quantum theory, speaks of "profoundly true statements the opposites of which likewise contain deep verities."
