D. Wandschneider’s scientific contributions

The criticism formulated by L. B. Puntel concerning the theory of dialectic proposed by the author is rejected. Puntel's attempt at explicating predication by means of (second order) predicate logic fails: It misjudges predication being already presupposed for the possibility of predicate logic, thus belonging to the transcendental conditions of formal predicate logic, so that predication itself cannot be further explicated by means of such logic. What is in fact criticized by Puntel is something like an artefact of formalization. The unreflected application of formal logic here generates problems instead of solving them.
