It is my opinion that everything must be based on a simple idea. And it is my opinion that this idea, once we have finally discovered it, will be so compelling, so beautiful, that we will say to one another, yes, how could it have been any different.

I like to think that someone will trace how the deepest thinking of India made its way to Greece and from there to the philosophy of our times

We live on an island surrounded by a sea of ignorance. As our island of knowledge grows, so does the shore of our ignorance.

The observer cannot be left out of the description of the observation.

Time, among all concepts in the world of physics, puts up the greatest resistance to being dethroned from ideal continuum to the world of the discrete, of information, of bits.... Of all obstacles to a thoroughly penetrating account of existence, none looms up more dismayingly than 'time.' Explain time? Not without explaining existence. Explain existence? Not without explaining time. To uncover the deep and hidden connection between time and existence ... is a task for the future.

Now is the time for everyone who believes in the rule of reason to speak up against pathological science and its purveyors.

It from bit symbolizes the idea that every item of the physical world has at bottom...an immaterial source and explanation...that all things physical are information-theoretic in origin and that this is a participatory universe.
