Scientists, like everyone else, are social animals, and at any given time work within a shared set of assumptions and methods, often called a paradigm. But the current scientific paradigm or worldview is immensely influential. It goes beyond the subtribes of scientists, each within their specialized discipline, because the sciences have been so successful. Their achievements touch all our lives through technologies and through modern medicine. Our intellectual world has been transformed through an immense expansion of our knowledge, down to the most microscopic particles of matter and out into the vastness of space, with hundreds of billions of galaxies in an ever-expanding universe.

But now that science and technology seem to be at the peak of their powers, when their influence has spread all over the world and when their triumph seems indisputable, unexpected problems are disrupting the sciences from within. Most scientists take it for granted that these problems will eventually be solved by more research along established lines, but some, including myself, think that they are symptoms of a deeper malaise.

Contemporary science is based on the philosophy of materialism, which claims that all reality is material or physical. There is no reality but material reality. Consciousness is a by-product of the physical activity of the brain. Matter is unconscious. Evolution is purposeless. God exists only as an idea in human minds, and hence in human heads.

These beliefs are powerful not because most scientists think about them critically, but because they don’t. The facts of science are real enough, and so are the techniques that scientists use, and so are the technologies based on them. But the belief system that governs conventional scientific thinking is an act of faith. The biggest scientific delusion of all is that science already knows the answers. It says details still need working out, but the fundamental questions are settled, in principle.
