Based on a conference held at Burg Wartenstein, Austria in 1968, organized by anthropologist Gregory Bateson and observed and interpreted by Mary Catherine Bateson. This classic on the mismatch between natural processes and human mental capacities and about the needed process of epistemological change was first published in 1972 (Knopf) and is reissued with a wonderful new foreword and afterword by the author.
