Back in 1943 a Dutch physician, David Karel de Jongh, wrote a PhD dissertation on homeopathy. It was based on his experience working in a homeopathic hospital and on all the published information he could find, and was highly critical of homeopathy. It was an impressive opus, with over 200,000 words. It is way too long for the average reader to wade through; and since it is in Dutch, few of us could read it even if we wanted to. Jan Willem Nienhuys, secretary of the Dutch skeptics’ organization Skepsis, has done us a great favor by summarizing its contents and updating it with information about recent developments. He has kindly had his summary translated into English and published in full on the Skepsis website. He comments “Basically Dr. de Jongh’s conclusions were that homeopathy is an incoherent mess.”
