Gregory Bateson’s contributions to epistemology are so numerous that it is impossible to even show their main implications in this memorial. His discovery of a context, of a meta-information qualifying the content (the formal ‘information’) led to the formulation of a complex communication theory. The idea of ‘double bind’ was only one – although a prominent – concept emerging from these investigations. More important, however, was that it became possible to think about topics such as psychiatric diseases, communication, information, mind and others from a totally different point of view. This e-book looks at how Bateson’s epistemology is understood and applied today, with some surprising results.
