It might be related to a 'life force' or vitalism. Here Nunn seems to reverse my intent. The term 'essence' is unfortunate in its modern meaning. Perhaps in Aquinas' time this term cold be taken as something different from 'basic' and 'at the heart of the matter'. Nunn's mention of the collapser of the wave function is a point clearly within the traditional quantum physics view of quantum measurement.
Presentation is a non-conceptual form of 'representation'.
Instead of 'state reduction' organisms use the process of 'spontaneous symmetry breaking' a process well-known in the quantum field theory of condensed matter physics. As I understand it, both Bohm and Sarfatti conform to most of the basic premises of traditional quantum mechanics. In any case, my view is incompatible with their ontological stance. There's the Heisenberg choice concerning what aspect of the world the 'quantum measurer' chooses or is able to observe. There is also the Dirac choice, thought to be random, concerning which of the range of possibilities entailed by a particular Heisenberg choice will become concrete.
