Fritjof Capra, internationally renowned physicist and author of the best-selling book The Tao of Physics, places the issue of unity from the point of view of contemporary physics in this work, including in comparison to the religious or mystical view of ancient Eastern traditions.
In the chapter “The Unity of All Things” he examines how quantum theory and recent experiments in the field of subatomic particle physics tend to corroborate and come very close to the mystics’ worldview.
There is no need to repeat here such theories and scientific experiments, which are known to people in the field, and can be complicated for lay people on the subject. We will quote only one paragraph in which Fritjof Capra summarizes his position on this subject:
“Modern physics, of course, works in a very different perspective and cannot go so far (as far as the mystic’s view is concerned) in the experience of the unity of all things. But in atomic theory it took a big step towards the mystics’ worldview. Quantum theory has abolished the notion of fundamentally separate objects, introduced the concept of the participant to replace that of the observer, and may even find it necessary to include human consciousness in its description of the world. She came to see the universe as an interconnected network of physical and mental relationships, whose parts are defined only through their connections to the whole.” (Fritjof Capra. The Tao of Physics, p. 129)
