ABSTRACT
It is appropriate to begin with a few words of explanation for what is to follow. I have been, and remain, entirely dedicated to the idea that modelling is the essence of science, and the habitat of all epistemology. Although I have concentrated my efforts on biology, and the nature of organisms, I have also asserted for a long time that human systems and organisms are very much alike; i.e., share or realize many common models. I was a pioneer in the wide deployment of mathematical ideas for purposes of modelling, particularly in the area of stability theory; indeed, I wrote perhaps the first modern text devoted to this purpose (Rosen 1970).
