“The greatest threat to progress is not ignorance, but the illusion of knowledge ”. This quote from American historian Daniel Boorstin, an exhortation to methodical doubt and intellectual humility, embodies the essence of a provocative book – “The hidden half”(Ed. Bollati Boringhieri, pp. 326, euro 24) – written by the essayist and radio journalist Michael Blastland.
