Professor Bruno Latour delivers the Gifford Lecture series entitled "Facing Gaia. A new enquiry into Natural Religion". Lecture 6: Inside the 'Planetary Boundaries': Gaia's Estate Although the resources of "paganism", New Age cults, renewed themes of Christian incarnation, and process theology offer rich mythological insights, it is not clear whether they are at the scale and sensitivity needed to face Gaia. A search for collective rituals should begin with works of art and experiments able to explore in sufficient detail the scientific and political composition of the common world. Recorded on Thursday 28 February 2013 at St Cecilia's Hall, the University of Edinburgh.
