Chapter 12: The Principle of Computational Equivalence

Section 4: The Validity of the Principle

Human thinking [and PCE]

The discovery in this book that even extremely simple programs can give rise to behavior vastly more complex than expected casts suspicion on any claim that programs are fundamentally unable to reproduce features of human thinking. But complete evidence that human thinking follows the Principle of Computational Equivalence will presumably come only gradually as practical computer systems manage to emulate more and more aspects of human thinking. (See page 628.)
