This is reminiscent of Spinoza and the Indian Seers who averred ” Absolute Being is that which Is”.
When De Broglie postulated that the electron is both a particle and a wave, the New Physics ( Quantum Physics ) was speaking the language of the mystics !
Is Man good-bad ? Yes, says Mysticism. Man is a composite creature. He is both good and bad, Dr Jekyll and Mr Hyde and all human beings are dual personalities. Man is a contradiction ! Man is a paradox. Like the Electron, which is both a particle and a wave.
Shroedinger opined that electrons are standing Waves!
Heisenberg, another quantum physicist, opined that the highest levels of philosophy and physics are the same, in his magnum opus ” Physics and Philosophy”.
