Human nature and the limits of science - John Dupr

John Dupr warns that our understanding of human nature is being distorted by two faulty and harmful forms of pseudo-scientific thinking. Not just in the academic world but increasingly in everyday life, we find one set of experts seeking to explain the ends at which humans aim in terms of evolutionary theory, and another set of experts using economic models to give rules of how we act to achieve those ends. Dupr charges this unholy alliance of evolutionary psychologists and rational-choice theorists with scientific imperialism: they use methods and ideas developed for one domain of inquiry in others where they are inappropriate. He demonstrates that these theorists' explanations do not work, and furthermore that if taken seriously their theories tend to have dangerous social and political consequences. For these reasons, it is important to resist scientism - an exaggerated conception of what science can be expected to do for us. To say this is in no way to be against science - just against bad science. Dupr restores sanity to the study of human nature by pointing the way to a proper understanding of humans in the societies that are our natural and necessary environments. He shows how our distinctively human capacities are shaped by the social contexts in which we are embedded. And he concludes with a bold challenge to one of the intellectual touchstones of modern science: the idea of the universe as causally complete and deterministic. In an impressive rehabilitation of the idea of free human agency, he argues that far from being helpless cogs in a mechanistic universe, humans are rare concentrations of causal power in a largely indeterministic world. Human Nature and the Limits of Science is a provocative, witty, and persuasive corrective to scientism. In its place, Dupr commends a pluralistic approach to science, as the appropriate way to investigate a universe that is not unified in form. Anyone interested in science and human nature will enjoy this book, unless they are its targets.
