The paper presents a discussion between the author and the referee. The discussion is devoted essentially to the question, whether or not the Dirac particle has internal degrees of freedom, described nonrelativistically. The author's viewpoint is based on the radical approach, which may be described as the third modification of the space-time geometry (the first modification is the special relativity, the second one is the general relativity). The third modification generates purely dynamical methods of investigation, which are free of quantum principles, because they are not needed. On the contrary, the referee's viewpoint is the conventional one, based on the quantum principles. Application of the two different methods to the investigation of the Dirac particle is discussed.
