What is meant by the term "intelligence" and, once de- fined, how do we go about achieving a valid measurement of this faculty? This classic textbook, originally published in 1979, and now reissued with a new preface by Sybil Eysenck, incorporates a broad range of findings and reanalyzes much of the existing literature in this area. In The Structure and Measurement of Intelligence, Hans Eysenck draws on methods for determining the effect of genetics and environment on the development of intelligence and examines the validity of the term as defined in relation to internal as well as external criteria. He tests a number of hypotheses on intelligence against empirical research findings and considers various criticisms in detail. The significance of intelligence and its measurement in society are explored in depth. Eysenck greatly expands upon such questions as: Does IQ measure intelligence? How valid is the nature versus nurture argument? and, How might socioeconomic status influence one's intelligence? Designed primarily for students and scholars in psychology and education, this text will make thought-provoking reading for all concerned with the development and measurement of intelligence in the individual.

Topological psychology may be described non-technically as an attempt to comprehend human behavior in terms of the objects which are present, and of the relations among "events" taking place in a given environment ("life-span"). Lewin contends that it provides the basis for a truly scientific psychology. The Lewin's equation, B = ƒ(P, E), is a psychological equation of behavior developed by Kurt Lewin. It states that behavior is a function of the person in their environment. The equation is the psychologist's most well known formula in social psychology, of which Lewin was a modern pioneer. When first presented in Lewin's book "Principles of Topological Psychology," published in 1936, it contradicted most popular theories in that it gave importance to a person's momentary situation in understanding his or her behavior, rather than relying entirely on the past.

Without of course adopting a Platonic metaphysics, the eighteenth-century philosophes were Grecophiles who regarded the Athenian philosophers as their intellectual forbearers and mentors. So powerful was their identification with c1assification that ancient ideas were taken as keys to the design of the modem world, but usually the ideas were taken separately and as divided from their systematic context. The power of number was an idea the En lightenment thinkers deployed with their legendary passion and vigor, particularly as an instrument for social reconstruction. It is no exaggemtion to say that the role of quantities in contemporary social scientific theorizing cannot be understood with any depth absent a recollection of the philosophes' axial development of the notion of quantification. It is a commonplace that for the philosophes progress required releasing human abilities to have power over nature. Aprerequisite for this power was knowledge of the underlying causes of natural events, knowledge that required quantitative precision. Enlightenment thinkers were sufficiently aware of themselves as products of their time to appreciate the importance of a liberal social environment to the knowledge enterprise; the supposition that the reverse is also the case, that enhanced knowledge could advance social conditions, came easily.
