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

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.

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 is expanding, and with it our vision of the universe. although this new and constantly changing view may not always give us comfort, it does have the virtue of truth according to our most effective resources for acquiring knowledge. No philosophy, moral outlook, or religion can be inconsistent with the findings of science and hope to endure among educated people.

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.
