The Mentifex AI project has made a double contribution to artificial intelligence: theory and software. The AI4U book from 2002 retains value over time by illustrating the AI theory with diagrams at the start of each chapter for any given AI mind-module. Each diagram or flowchart shows the interaction of mind-modules to achieve thinking and reasoning and Natural Language Understanding.
