George Towner received an M.A. in Philosophy from U.C. Berkeley and joined the Kaiser Foundation Research Institute as Assistant Director in basic research on the metabolism of primitive organisms. He then switched to electronics, becoming President of Berkeley Instruments Corporation and receiving three patents for digital data systems. For the past 24 years he has been a senior member of the technical staff of Apple Inc., where he has written several books on computer technology. His major work, however, is a trilogy of traditional philosophy: The Architecture of Knowledge (1980), Processes of Knowledge (2001), and The Reality of Knowledge (2011).
