At the subatomic level, matter does not exist with certainty at definite places, but rather shows "tendencies… — Fritjof Capra

While the new physics was developing in the 20th century, the mechanistic Cartesian world view and the principles of Newtonian physics maintained their strong influence on Western scientific thinking, and even today many scientists still hold to the mechanistic paradigm, although physicists themselves have gone beyond it.

However, the new conception of the universe that has emerged from modern physics does not mean that Newtonian physics is wrong, or that quantum theory, or relativity theory, is right. Modern science has come to realize that all scientific theories are approximations to the true nature of reality; and that each theory is valid for a certain range of phenomena.

My main professional interest during the 1970s has been in the dramatic change of concepts and ideas that has occurred in physics during the first three decades of the century, and that is still being elaborated in our current theories of matter. The new concepts in physics have brought about a profound change in our world view; from the mechanistic conception of Descartes and Newton to a holistic and ecological view, a view which I have found to be similar to the views of mystics of all ages and traditions.

As Eastern thought has begun to interest a significant number of people, and meditation is no longer viewed with ridicule or suspicion, mysticism is being taken seriously even within the scientific community An increasing number of scientists are aware that mystical thought provides a consistent and relevant philosophical back ground to the theories of Contemporary science, a conception of the world in which the scientific discoveries of men and women can be in perfect harmony with their SpirItual aims and religious beliefs.
