The visible world is the invisible organization of energy.

We surely stand at the threshold of a great adventure of the human spiritó a new synthesis of knowledge, a potential integration of art and science, a deeper grasp of human psychology, a deepening of the symbolic representations of our existence and feelings as given in religion and culture, the formation of an international order based on cooperation and nonviolent competition. It seems not too much to hope for these things.

Science shows us what exists but not what to do about it.

Science has explored the microcosmos and the macrocosmos; we have a good sense of the lay of the land. The great unexplored frontier is complexity.

The world changed from having the determinism of a clock to having the contingency of a pinball machine.

The great unexplored frontier is complexity ... I am convinced that the nations and people that master the new science of Complexity will become the economic, cultural, and political superpowers of the next century.

The capacity to tolerate complexity and welcome contradiction, not the need for simplicity and certainty, is the attribute of an explorer. Centuries ago, when some people suspended their search for absolute truth and began instead to ask how things worked, modern science was born. Curiously, it was by abandoning the search for absolute truth that science began to make progress, opening the material universe to human exploration.
