In the 17th century physics was a new frontier of science. In the 18th century chemistry had the same excitement. In the latter half of the 20th century, a new science has emerged. The same sense of adventure inspires some of the brightest minds to explore this new frontier: the study of symbolic systems.

Symbolic Systems attacks age-old questions about the relation between mind and the world, questions like the following. What is information? What is intelligence? How are they related? Is intelligence more than information processing? Does intelligence require a mind? For that matter, what is a mind? How are minds related to brains? Does intelligence require some sort of biologically-based brain? Or is it possible to create artifacts that process information in a way that we can call them intelligent?
