The Scientific and Medical Network organised a gathering on Friday 8th July to mark Rupert’s 80th birthday and reflect on his work. In this episode of the Sheldrake-Vernon Dialogues, Rupert and Mark Vernon discuss the day, recalling remarks made by speakers including Merlin Sheldrake, Jill Purce, David Lorimer and Pam Smart. They discuss a variety of themes seminal to Rupert’s work, from science as the calling to share in a living cosmos to the business of coping with sceptics, which is not without its amusing as well as tricky moments. The conversation celebrates the richness of an engaged and free approach to the study of the natural world, with its many mysteries, often active immediately around us everyday.
