Churchland provides a brief, enlightening introduction to this second edition, placing the writer to think in context and grounding the reader in a scientific environment that gave rise to Computer and the Brain. Although computer architecture slowly growing obsolete, von Neumann has given us a more lasting legacy in thinking about thinking.
