Logical Thought Based on Word Presentations

This paper is about the mechanisms of logical reasoning which would fit into a cognitive architecture based on the concepts of psychoanalytic metapsychology. As the results have to be based on a bionic approach beyond neurological findings a turn back to the roots of logic is required. According to psychoanalytical theory word presentations are the base of language on the one hand and connected to that the base of rational thought on the other. The paper shows, how a functional model of logical thought can be derived from basic metapsychological insights and how based on word presentations atomic propositions emerge from simple word presentations in a psyche. Finally it sketches briefly, how reasoning rules have to be handled based on the underlying model.
