Of materialism, [Werner Heisenberg] wrote:
“[This] frame was so narrow and rigid that it was difficult to find a place in it for many concepts of our language that had always belonged to its very substance, for instance, the concept of mind, of the human soul or of life. Mind could be introduced into the general picture only as a kind of mirror of the material world.”
Today we live in the 21st century, and it seems that we are still stuck with this narrow and rigid view of the things. As Rupert Sheldrake puts it in his new book, published this week, The Science Delusion: “The belief system that governs conventional scientific thinking is an act of faith, grounded in a 19th-century ideology.”
That's provocative rhetoric. Science an act of faith? Science a belief system? But then how else to explain the grip of the mechanistic, physicalist, purposeless cosmology? As Heisenberg explained, physicists among themselves have long stopped thinking of atoms as things. They exist as potentialities or possibilities, not objects or facts. And yet, materialism persists.
Heisenberg recommended staying in touch with reality as we experience it, which is to say holding a place for conceptions of mind and soul. The mechanistic view will pass, he was certain. In a way, Sheldrake's scientific career has been devoted to its overthrow. He began in a mainstream post as director of studies in cell biology at Cambridge University, though he challenged the orthodoxy when he proposed his theory of morphogenetic fields.
This is designed to account for, say, the enormously complex structure of proteins. A conventional approach, which might be described as bottom-up, has protein molecules “exploring” all possible patterns until settling on one with a minimum energy. This explanation works well for simple molecules, like carbon dioxide. However, proteins are large and complicated. As Sheldrake notes: “It would take a small protein about 10^26 years to do this, far longer than the age of the universe.”
As a result, some scientists are proposing top-down, holistic explanations. Sheldrake's particular proposal is that such self-organising systems exist in fields of memory or habit.
