Post naivety or post naive realism (or post naive materialim, or post materialism) acknowledges the full implications of the most profound statement of modern neuroscience: that the world we experience is a construct created by the principle of the brain, the same principle that creates our experience of self. Circles, Myth and Imagination is a series of ten connected short essays in post-naive realism, explored through ancient myth, musical science, quantum physics, brain science, the renaissance musician and philosopher Marsilio Ficino, Plato and William Blake.
