In his new book “A Beautiful Question” Nobel prize winning physicist Frank Wilczek writes that Niels Bohr, one of the fathers of quantum mechanics, said that you can recognize a deep truth by the feature that its opposite is also a deep truth.
Makes sense in that beyond the dualities of our senses and the language we use to convey such truths there is Truth that is not limited by our truth statements, our concepts.
So two opposite statements can be true because both capture some of our limited grasp of reality.
Most things we hold true just aren’t all that deep. Just working definitions and constructs that often don’t work all that well except to momentarily shield us from the painfully hard stuff. And they don’t do that very well without a large investment of energy. The real illusion is to convince yourself that the illusion works.
