James Clark, who along with his wife Valerie, owns and operates the antique graphics gallery, I Desire Vintage Posters, has worked for a long time upon the issues comprising the present book. Some steps along the way have taken the form of a three-part publication, The Problem Of Fundamental Ontology (Toronto Limits Book Company, 1973, 1977, 1981), and an essay, "An Inclusive Option Within Heraclitean Exclusivity", finding its way into the proceedings of a colloquium, Ati del Symposium Heracliteum 1981 (Roma: Edizioni dell’Ateneo 1983)
