Gradually, physicists began to realise that nature, at the atomic level, does not appear as a mechanical universe composed of fundamental building blocks, but rather as a network of relations, and that, ultimately, there are no parts at all in this interconnected web. Whatever we call a part is merely a pattern that has some stability and therefore captures our attention.

Whenever the essential nature of things is analysed by the intellect, it must seem absurd or paradoxical. This has always been recognized by the mystics, but has become a problem in science only very recently.

Ecology and spirituality are fundamentally connected, because deep ecological awareness, ultimately, is spiritual awareness.

Subatomic particles do not exist but rather show 'tendencies to exist', and atomic events do not occur with certainty at definite times and in definite ways, but rather show 'tendencies to occur'.

As long as we do science, some things will always remain unexplained.

The mathematical framework of quantum theory has passed countless successful tests and is now universally accepted as a consistent and accurate description of all atomic phenomena. The verbal interpretation, on the other hand - i.e., the metaphysics of quantum theory - is on far less solid ground. In fact, in more than forty years physicists have not been able to provide a clear metaphysical model.

Genuine mental health would involve a balanced interplay of both modes of experience, a way of life in which one's identification with the ego is playful and tentative rather than absolute and mandatory, while the concern with material possessions is pragmatic rather than obsessive.
