Denman's criticism of the idea of usefully applying chaos theory to psychoanalysis is seen in his disparaging remarks about Lacan's interest in knot theory, Matte Blanco's application of set theory, and Jewish mystical (kabbalistic) interest in calculating the numerical values of certain words, all of which he lumps together as useless endeavors. He sees the authors as humanizing mechanisms and mechanizing humans, objecting in particular to seeing human psychology in terms of watch mechanisms. His principal objection to chaos theory re psychoanalysis is that “psychoanalysis has not yet conclusively been shown to be efficacious. …” Denman, therefore, does not take seriously any of the possibilities inherent in Priel and Schreiber.
