Nature is all that we think we know plus all that we don't know whether or not we know that we don't know it.

You don't belong to you. You belong to the Universe and you're here to serve.

I'm not trying to counsel any of you to do anything really special except dare to think. And to dare to go with the truth. And to dare to really love completely.

I am enthusiastic over humanity’s extraordinary and sometimes very timely ingenuity. If you are in a shipwreck and all the boats are gone, a piano top buoyant enough to keep you afloat that comes along makes a fortuitous life preserver. But this is not to say that the best way to design a life preserver is in the form of a piano top. I think that we are clinging to a great many piano tops in accepting yesterday’s fortuitous contrivings as constituting the only means for solving a given problem.

We have reached the point where we are now possessed of sufficient information for each individual human to dare to exercise the option to "make it" rather than having to depend on the decisions of an educated elite.

A problem adequately stated is a problem well on its way to being solved.

Our power is in our ability to decide.
