In this posthumous publication, Gould provides a thorough historical overview of the development of scientific thought in various fields. He attempts to bridge the gap between the humanities/social sciences and the traditional idea of science as it finds expression in the natural sciences like astronomy, physics, geology etc. The title refers to hedgehogs that establish themselves so successfully in a particular field that they can forever keep their competitors at a distance, and to foxes that in their turn spread the seed of knowledge through their genius and versatility. The fox and the hedgehog are the models of how the sciences and humanities should interact, because Gould believed that neither single strategy would work.
But a fruitful merger of these seemingly polar opposites could, with the necessary goodwill and restraint, be conjoined into a diverse but common enterprise of power and unity. The book is a plea for increased understanding between the humanities and the natural sciences.
He encourages natural scientists to improve their communication skills and to read beyond their field of specialty, and he criticizes those in the humanities who have no knowledge or understanding of the natural sciences. This can lead to the embarrassing stupidities so well documented in the book Intellectual Impostures (Fashionable Nonsense) by Alan Sokal and Jean Bricmont.
The Hedgehog, the Fox and the Magister's Pox is an engaging text and a stimulating read. It is accessible enough for the general reader and although not considered as an example of his best writing, definitely worth a read.
