The Subject of Our Discussions

We discuss how the apparently objective probabilities predicted by quantum mechanics can be treated in the framework of Bayesian probability theory, in which all probabilities are subjective. Our results are in accord with earlier work by Caves, Fuchs, and Schack, but our approach and emphasis are different. We also discuss the problem of choosing a noninformative prior for a density matrix.

A number of philosophers and scientists have discussed the possibility of inseparability between the subject (i.e., the observer) and the object (i.e., the observed universe).In particular, it has recently been proposed that this inseparability may be obtained through the discrete physical universe being filled with the observer's continuous consciousness through quantum evolution with time going backwards.The proposal of a universe view with interwoven matter and mind through cyclical time bears a resemblance to Immanuel Kant's discussion of the Copernican Revolution in philosophy, where the priority shifted from the object to the subject.

Orch OR is reviewed with critical attention to the theory's epistemological claims. A modification of the Penrose-Hameroff hypothesis entailing state vector reduction by an eccentrically subjective agency is proposed. Empirically falsifiable implications of the revised model are discussed.
