In this study, we review the history of Christopher Alexander's works and point out why his approaches did not work as he intended. In "Notes on the Synthesis of Form", since he proposed the generating system of forms based on mathematical formal systems, forms generated by the system were merely the sum of the parts, and, in Pattern Language, there was no mechanism which ensures the generated whole was actually 'good' one. After these reviews, we searched for domains where Alexander has not explored, and found out he never tried to implement the system that has rules of tendency of behaviors (or forces, in his terminologies). We indicate that this approach has possibility for the design of diversity.
