The measurement problem of quantum theory is discussed, and the difficulty of trying to solve it within the confines of a local, Lorentz-invariant physics is emphasised. This leads to the obvious suggestion to seek a solution beyond physics, in particular, by introducing the concept of consciousness. The resulting dualistic model, in the natural form suggested by quantum theory, is shown to differ in several respects from the classical model of Descartes, and to suggest solutions to some of the long-standing problems (...) concerning the relation of consciousness to the physical world.

We present a pragmatic analysis of the different meanings assigned to the term “local realism” in the context of the empirical violations of Bell-type inequalities since its inception in the late 1970s. We point out that most of them are inappropriate and arise from a deeply ingrained prejudice that originated in the celebrated 1935 paper by Einstein-Podolski-Rosen. We highlight the correct connotation that arises once we discard unnecessary metaphysics.

Stapp's attempt to derive Bell's Inequality from a weak locality condition while retaining indeterminism, requires careful scrutiny to ensure unambiguous definitions and valid reasoning. Such scrutiny reveals that the argument is fallacious. This result is obtained without commitment to any particular formal analysis of truth conditions for counterfactuals nor to conditions for world similarity.
