The imagination is often regarded as a valuable but fanciful capacity. But what if imagination were not an optional extra, or even the possession of human beings alone, but a fundamental feature of reality? In this episode of the Sheldrake-Vernon Dialogues, Rupert Sheldrake and Mark Vernon draw on the ideas of William Blake to explore Blake’s insistence that “nature is imagination itself!”. They discuss how the understanding of the imagination has contracted in recent times, though also how modern science is a remarkable exercise in the imagination. They consider matters from how the Platonic notion of ideas relates to cosmic and evolutionary novelty, to whether angels can be said to be imaginative and creative. Mark’s new book is Awake! William Blake and the Power of the Imagination.
