Query: Lessons of spin and torsion: Reply to ``Consistent coupling to Dirac
  fields in teleparallelism"   In reply to the criticism made by Mielke in the pereceding Comment [Phys.
Rev. D69 (2004) 128501] on our recent paper, we once again explicitly
demonstrate the inconsistency of the coupling of a Dirac field to gravitation
in the teleparallel equivalent of general relativity. Moreover, we stress that
the mentioned inconsistency is generic for {\it all} sources with spin and is
by no means restricted to the Dirac field. In this sense the
$SL(4,R)$-covariant generalization of the spinor fields in the teleparallel
gravity theory is irrelevant to the inconsistency problem.
