“If physics leads us today to a world view which is essentially mystical, it returns, in a way, to its beginning, 2,500 years ago. ... This time, however, it is not only based on intuition, but also on experiments of great precision and sophistication, and on a rigorous and consistent mathematical formalism.”

“We have a closed circle of consistency here: the laws of physics produce complex systems, and these complex systems lead to consciousness, which then produces mathematics, which can then encode in a succinct and inspiring way the very underlying laws of physics that gave rise to it.”

“There are two types of people in the world, a solution-based person, and a sustainable person. A solution based person focuses on finding solutions to today’s problems. But, as for tomorrow’s problems, who cares? However, a sustainable person is the one that not only attempts to make an immediate fix, but also contemplates decisions for today, tomorrow and for years to come.”

“If we ask ourselves what is this wisdom which experience forces upon us, the answer must be that we discover the world is not constituted as we had supposed it to be. It is not that we learn more about its physical elements, or its geography, or the variety of its inhabitants, or the ways in which human society is governed. Knowledge of this sort can be taught to a child without in any way disturbing his childishness. In fact, all of us are aware that we once knew a great many things which we have since forgotten. The essential discovery of maturity has little if anything to do with information about the names, the locations, and the sequence of facts; it is the acquiring of a different sense of life, a different kind of intuition about the nature of things.”

“The world of physics is essentially the real world construed by mathematical abstractions, and the world of sense is the real world construed by the abstractions which the sense-organs immediately furnish. To suppose that the "material mode" is a primitive and groping attempt at physical conception is a fatal error in epistemology.”

“Consistency requires you to be as ignorant today as you were a year ago.”
