  In this paper it is argued that Barad's Agential Realism, an approach to
quantum mechanics originating in the philosophy of Niels Bohr, can be the basis
of a 'theory of everything' consistent with a proposal of Wheeler that
observer-participancy is the foundation of everything. On the one hand,
agential realism can be grounded in models of self-organisation such as the
hypercycles of Eigen, while on the other agential realism, by virtue of the
'discursive practices' that constitute one aspect of the theory, implies the
possibility of the generation of physical phenomena through acts of
specification originating at a more fundamental level. Included in phenomena
that may be generated by such a mechanism are the origin and evolution of life,
and human capacities such as mathematical and musical intuition.
