Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning.

The intuitive mind is a sacred gift and the rational mind is a faithful servant. We have created a society that honors the servant and has forgotten the gift. We will not solve the problems of the world from the same level of thinking we were at when we created them. More than anything else, this new century demands new thinking: We must change our materially based analyses of the world around us to include broader, more multidimensional perspectives.

Concepts that have proven useful in ordering things easily achieve such authority over us that we forget their earthly origins and accept them as unalterable givens.

Agreements about what is good or not, are usually not worth much. It is very much like art, is it not an art to lead a good life?

What I see in Nature is a grand design that we can understand only imperfectly, one with which a responsible person must look at with humility.

The only justification for our concepts and systems of concepts is that they serve to represent the complex of our experiences; beyond this they have not legitimacy.

It's very depressing to live in a time where it's easier to break an atom than a prejudice.
