Chiastic order is an ancient expression for cross-classification. As such, it is the primordial form of non-quantified modelling and combinatory heuristics. This book presents an epistemological history of non-quantified modelling: its prehistory in the form of rhetorical and epistemic chiasmus; its early (pre-symbolic) use by Plato as a cross-order (paradigmatic) modelling method; its prototype development by Ramon Llull as a heuristic ars combinatoria; its “modern” use by Gottfried Leibniz based on a calculus of concepts; and Fritz Zwicky’s 20th-century promotion of the “morphological approach”. Examples of contemporary computer-aided combinatorial modelling are presented in the areas of operational research, policy analysis, scenario development and design theory.
Tom Ritchey is former Research Director of the Institution for Technology Foresight and Assessment in Stockholm. He is a modelling theorist with a background in operational research, decision theory and the history and philosophy of science.
