From The Mental Universse, Nature, Vol 436,7 July 2005:
Niels Bohr, Nobel Prize laureate in Physics, The Philosophical Writings of Niels Bohr, Vol. I, (Woodbridge, Connecticut: Ox Bow, 1987), p.54:Physicists shy from the truth because the truth is so alien to everyday physics. A common way to evade the mental Universe is to invoke ‘decoherence’ — the notion that ‘the physical environment’ is sufficient to create reality, independent of the human mind. Yet the idea that any irreversible act of amplification is necessary to collapse the wave function is known to be wrong: in ‘Renninger-type’ experiments, the wave function is collapsed simply by your human mind seeing nothing. The Universe is entirely mental.
Werner Heisenberg, Nobel Prize laureate in Physics, Physics and Philosophy, (New York: Harper and Row, 1962), p.145:An independent reality, in the ordinary physical sense, can neither be ascribed to the phenomena nor to the agencies of observation.
Page 70:The ontology of materialism rested upon the illusion that the kind of existence, the direct "actuality" of the world around us, can be extrapolated into the atomic range. This extrapolation is impossible, however.
Materialism is insufficient to explain the non-local and uncertain behavioral characteristics of quanta. Alain Aspect conclusively proved that unobserved quanta cannot be considered to be discrete material objects, and proved that split photons must be considered to be the same global phenomena regardless of intervening distance since the determining observation of one immediately collapsed the qualities of the other into correspondence.If one wants to give an accurate description of the elementary particle—and here the emphasis is on the word "accurate"—the only thing which can be written down as description is a probability function. But then one sees that not even the quality of being...belongs to what is described.
One of the defining qualities of materialism is that the universe is comprised of discrete objects that have discrete characteristics and are located in a specific place at a specific time; without such objects, or particles, or even physical waves that actually exist in specified locations and as specified things, materialism breaks down into disjoint rationalizations and apologetics.
What does materialism mean when, at the most fundamental level, there is no "material" present? By "material" one must mean an identifiable, locatable, quantifiable thing; but it has been proven that no such "things" actually exist on their own outside of an observational collapse of potential states, have no definite location or characteristics, and can exist as a single global object in different locations.
It seems to me that materialists are clinging via apologetics and denial to a 19th-century Newtonian-era philosophy that simply cannot be supported via modern quantum experimentation.
The question is, with the known results of quantum experiments, why bother calling oneself a "materialist" when the "matter" that justified such a view in the 19th century has, upon closer examination, completely disappeared and has been replaced by informational and consciousness-dependent field theories which bear no significant relationship to the the concept of a "material" universe? Why torture, through twisted apologetics, a continued belief in such a thoroughly discredited ontological view?
