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.
