ABSTRACT
I carefully chose my title—”putting it all together”—intending it to have multiple meanings. First, Herbert Simon has indeed put it all together over the course of his career. Thus, this is a suitable title for the chapter that concludes a celebration of his cumulative work. But second, this title could be an echo of my William James lectures, Unified Theories of Cognition, given the Spring of 1987 at Harvard. Thus, this is a suitable title to provide a lead in for me to write about what preoccupies me these days—always a good thing for a commentator to do. Third, the title could refer to putting the chapters of this volume all together. After all, I am officially a discussant—and the final one at that. So I could do what I was hired to do.
