We need a vision of the better world in order to energize our drive to it, and Martin Schoenhals does an amazing job of providing a scientifically-based vision in Work, Love, & Learning in Utopia - Equality Reimagined. He is a cultural anthropologist who has taught at several universities, including Johns Hopkins, Columbia, and, currently, Appalachian State University, in Boone, North Carolina.
George Lakoff
The Brain & Progressive Messaging
Scott Wittkopf helps organizations & people learn to do effective progressive messaging through his firm, Frame for the Future. It's a bit ironic that the scientific research proves that people do not make their decisions based on scientific research, but on frames, and progressives have been doing an inferior job of harnessing this knowledge to support their goals. Based on the work of George Lakoff and others, there is great untapped potential for progressive causes.
