Linguistics expert George Lakoff, author of “Don’t Think of an Elephant,” “The Political Mind,” and many more books examining the power of language, is our guest for the October national call. He’ll share his recent work on the distinction between direct causation and systemic causation, which is the frame through which climate change can be better comprehended. Mr. Lakoff is recently retired from the University of California at Berkeley, where he was Professor of Cognitive Science and Linguistics.
