The specialist knows more and more about less and less. The generalist knows little about much, and is thus compelled to be an amateur in many fields. I know as good as nothing about quasicrystals and fractals, as they were discovered decades after my mathematics at school, so I have only been able to deal with them phenomenologically.

"Morphogenesis" in geometry is a subject in which I invite the reader to find and to discuss inaccuracies, incompletions, errors and omissions, and thus perhaps, via antitheses, to find new syntheses. For me as an architect, the retrospective connection of many phenomena of architecture to the knowledge gained from geometry as a science, is important. As objective we still have the search for a complete and final system within which non-systematic phenomena can also be incorporated, such as amorphous glas with the structured crystals..
