  1. Jeffrey M. Schwartz, Henry P. Stapp & Mario Beauregard, Quantum Physics in Neuroscience and Psychology: A Neurophysical Model of Mind–Brain Interaction.
    Neuropsychological research on the neural basis of behaviour generally posits that brain mechanisms will ultimately suffice to explain all psychologically described phenomena. This assumption stems from the idea that the brain is made up entirely of material particles and fields, and that all causal mechanisms relevant to neuroscience can therefore be formulated solely in terms of properties of these elements. Thus, terms having intrinsic mentalistic and/or experiential content (e.g. ‘feeling’, ‘knowing’ and ‘effort’) are not included as primary causal factors. This (...)

    It is argued on the basis of certain mathematical characteristics that classical mechanics is not constitutionally suited to accommodate consciousness, whereas quantum mechanics is. These mathematical characteristics pertain to the nature of the information represented in the state of the brain, and the way this information enters into the dynamics.

  3. Henry P. Stapp, Causally Effective Free Will.
    The mainstream view today in neuroscience, biology, psychology, and philosophy, is that your conscious will has no effect upon your bodily actions beyond what is already caused by purely mechanical processes acting alone. Thus you are claimed to be, in essence, a mechanical automaton, with perhaps some elements of pure chance thrown in. Your natural belief that your willful efforts can have physical effects is called, accordingly, “The Illusion of Conscious Will”.

  5. Henry P. Stapp, Retrocausal Effects as a Consequence of Orthodox Quantum Mechanics Refined to Accommodate The Principle of Sufficient Reason.
    The principle of sufficient reason asserts that anything that happens does so for a reason: no definite state of affairs can come into being unless there is a sufficient reason why that particular thing should happen. This principle is usually attributed to Leibniz, although the first recorded Western philosopher to use it was Anaximander of Miletus. The demand that nature be rational, in the sense that it be compatible with the principle of sufficient reason, conflicts with a basic feature of (...)

    Alfred North Whitehead in his book Process and Reality describes the history of the universe in terms of a process of ‘creative advance into novelty.’ This advance is produced by a collection of happenings called ‘actual occasions’, or ‘actual entities’. Each actual entity has an associated actual world, and it arises from its own peculiar actual world. (PR 284). Two occasions are termed ‘contemporary’ if neither lies in the actual world of the other. A key issue is whether the words (...)

    It is widely believed by both scientists and philosophers that consciousness, as we experience it, was not always present in this universe, but emerged gradually from a more purely physical stratum in conjunction with the development of biological systems, and, in particular, nervous systems. But if one assumes that the physical foundation from which consciousness emerged is adequately described by classical physical theory then one is put in a quandry by the deterministic character of that theory. For the dynamical completeness (...)

    The data emerging from the clinical and brain studies described above suggest that, in the case of OCD, there are two pertinent brain mechanisms that are distinguishable both in terms of neuro-dynamics and in terms of the conscious experiences that accompany them. These mechanisms can be characterized, on anatomical and perhaps evolutionary grounds, as a lower-level and a higher-level mechanism. The clinical treatment has, when successful, an activating effect on the higher-level mechanism, and a suppressive effect on the lower-level one.

  17. Henry Stapp, Introduction.
    Quantum theory has been formulated in several different ways. The original version was ‘Copenhagen’ quantum theory, which was formulated as a practical set of rules for making predictions about what we human observers would observe under certain well-defined sets of conditions. However, the human observers themselves were excluded from the system, in much the same way that Descartes excluded human beings from the part of the world governed by the natural physical laws.

    This "axiom" must be used with great care. It is well-known that the formalism of Relativistic Quantum Field Theory (RQFT) is 'Relativistic" in the sense that it allows no "signal" to be transmitted faster than the speed of light. So RQFT does conform to "The FIN Axiom" if by "effectively transmitted" one is referring to the transmission of a "signal". Here a "signal" means a controllable dependence of a faraway observable upon a sender's choices (of how he will act); a (...)

This question is an aspect of the long-standing problem of the relationship between mind and matter, which has a history dating back to the time of the ancient Greeks. The issue was rekindled by the rise of Newtonian physics during the seventeenth century, and it generated a huge body of speculation and argumentation (...)

    In the context of theories of the connection between mind and brain, physicalism is the demand that all is basically purely physical. But the conception of “physical” embodied in this demand is characterized essentially by the properties of the physical that hold in classical physical theories. Certain of those properties contradict the character of the physical in quantum mechanics, which provides a better, more comprehensive, and more fundamental account of phenomena. It is argued that the difficulties that have plagued physicalists (...)

    I just returned from a small conference attended by Basil Hiley, among a pestigious group of 17. An Oxford Philosopher of Science, S. Saunders, asserted strongly a point that I have often made, namely that the theory has never been extended to the relativistic case involving particle creation. Hiley did not disagree, but I believe admitted that this was indeed the case. So that is one reason why the theory as it stands is inadequate.

The two approaches appear to be extremely different, both in their technical forms, and in their philosophical underpinnings. Heisenberg arrived to his theory by effectively renouncing the idea of trying to represent a physical system, such as a hydrogen atom for example, as a structure in space-time, but by instead, following the (...)

    A simple exactly solvable model is given of the dynamical coupling between a person’s classically described perceptions and that person’s quantum mechanically described brain. The model is based jointly upon von Neumann’s theory of measurements and the empirical findings of close connections between conscious intentions and synchronous oscillations in well separated parts of the brain. A quantum-Zeno-effect-based mechanism is described that allows conscious intentions to influence brain activity in a functionally appropriate way. The robustness of this mechanism in the face (...)

    Classical physics is a theory of nature that originated with the work of Isaac Newton in the seventeenth century and was advanced by the contributions of James Clerk Maxwell and Albert Einstein. Newton based his theory on the work of Johannes Kepler, who found that the planets appeared to move in accordance with a simple mathematical law, and in ways wholly determined by their spatial relationships to other objects. Those motions were apparently independent of our human observations of them.
