Erwin Schroedinger – Nobel Prize Laureate in Physics “Consciousness cannot be accounted for in physical terms. For consciousness is absolutely fundamental. It cannot be accounted for in terms of anything else.”;

Sir James Jeans – physicist, astronomer, and mathematician “I am inclined to the idealistic theory that consciousness is fundamental, and that the material universe is derivative from consciousness, not consciousness from the material universe… The universe seems to me to be nearer to a great thought than to a great machine. It may well be, it seems to me, that each individual consciousness ought to be compared to a cell in a universal mind.”
“There is a wide measure of agreement that the stream of knowledge is heading towards a non-mechanical reality; the universe begins to look more like a great thought than a great machine. Mind no longer appears as an accidental intruder into the realm of matter. We are beginning to suspect that we ought rather to hail [Cosmic] mind as the creator and governor of the realm of matter.” The Mysterious Universe (New York: Macmillan, 1932), 186. “It looks more and more certain that the only way to explain the universe is to maintain that it exists in the mind of some eternal [Cosmic] spirit”

Max Planck – Nobel Prize Laureate in Physics “I regard consciousness as fundamental. I regard matter as a derivative of consciousness” “As a man who has devoted his whole life to the most clear headed science, to the study of matter, I can tell you as a result of my research about atoms this much: There is no matter as such. All matter originates and exists only by virtue of a force which brings the particle of an atom to vibration and holds this most minute solar system of the atom together. We must assume behind this force the existence of a conscious and intelligent mind. This [Cosmic] mind is the matrix of all matter.” Das Wesen der Materie, 1944

George Wald – Nobel Prize Laureate in Biology “Mind, rather than emerging as a late outgrowth in the evolution of life, has existed always as the matrix, the source and condition of physical reality—the stuff of which physical reality is composed is mind-stuff. What we recognize as the material universe, the universe of space and time and elementary particles and energies, is then an avatar, the materialization of primal mind. In that sense there is no waiting for consciousness to arise. It is there always”.
“It has occurred to me lately—I must confess with some shock at first to my scientific sensibilities—that both questions [the origin of consciousness and the origin of life from nonliving matter] might be brought into some degree of congruence. This is with the assumption that mind, rather than emerging as a late outgrowth in the evolution of life, has existed always as the matrix, the source and condition of physical reality—the stuff of which physical reality is composed is mind-stuff. It is mind that has composed a physical universe that breeds life and so eventually evolves creatures that know and create: science-, art-, and technology-making animals.” His address to the Quantum Biology Symposium titled Life And Mind In The Universe

Sir Arthur S. Eddington – astronomer, physicist “All through the physical world runs that unknown content, which must surely be the stuff of [Cosmic] consciousness. Here is a hint of aspects deep within the world of physics, and yet unattainable by the methods of physics. Space, Time and Gravitation: An Outline of the General Relativity Theory (1920) “The idea of a universal mind or Logos would be, I think, a fairly plausible inference from the present state of scientific theory.”

Roger Penrose – mathematical physicist, mathematician “…the contemporary understanding of material is very different now from the way it used to be. If we consider what matter really is, we now understand it as much more of a mathematical thing…But I think that matter itself is now much more of a mental substance…” Journal of Consciousness Studies 1:24

Freeman Dyson – theoretical physicist, mathematician “[Is consciousness] primary or an accidental consequence of something else? The prevailing view among biologists seems to be that the mind arose accidentally out of molecules of DNA or something. I find that very unlikely. It seems more reasonable to think that mind was a primary part of nature from the beginning and we are simply manifestations of it at the present stage of history.” Interview with Freeman Dyson in U.S.News and World Report, April 18, 1988, 72.
