ABSTRACT
A link between the idea of a force-field, in the sense of a field of attraction or a gravitational nucleus, with the spatial siting of industries and their development in time, is to be found in Andreas Predohl and Francois Perroux. The economic concept of market has some similarity with polycentric social fields, such as those described by Lindblom or Norton Long. In connection with 'the application of mathematical thinking in the measurement of behaviour', Coleman deals with a field-diagram of model-deliberations constructed by Homans and Simon. The idea of a simultaneity-model, showing instances of simultaneous causation, has certain things in common with the basic conception of field-theory. Milton Yinger pursues Lewin's psychological and sociological field-theory in a manner that is utterly different from the method author have adopted in the present book. The claim of Yinger's fields goes far beyond that of the economic determination-models, which only offer the basis for acts of political decision.
