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 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.

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

Science cannot resolve moral conflicts, but it can help to more accurately frame the debates about those conflicts.

There was emptiness more profound than the void between the stars, for which there was no here and there and before and after, and yet out of that void the entire plenum of existence sprang forth.

Possession of a program with unique analytic capabilities puts a scientist in as much of a priveleged position to make new discoveries as the possession of a powerful telescope.

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.
