After receiving his Ph.D. in philosophy from the University of Texas at Austin Bill Meacham spent many years as a computer programmer, systems analyst and project manager. Now an independent scholar in philosophy, he brings the precision required for good software development to the analysis of philosophical concepts and to the deep questions posed by philosophy: What is real? How do we know what is real? And what shall we do about what is real? His writings can be found at http://www.bmeacham.com.
