Update 2019: These links seem to be dead, but the pdf of the lectures can be found here; and the videos here. The lectures are now available as a book – details here.
Bruno Latour has made the text of his Gifford lectures available as a pdf on his site –Facing Gaia: Six lectures on the political theology of nature. Thanks to Owain Jones for the link (it seems this may have been available for a while; but news to me). The lectures were all video-recorded and I linked to them a while back – the links are all at the Edinburgh site.

Link for pdf files for the Lectures do not work
This post is almost 18 months old – I guess Latour removed them from his site.
Saw it for sale in Polity Catalog, $64 hard cover, $22.95 paperback.
“Facing Gaia: A New Enquiry into Natural Religion” Due out in Dec 2015, says ebook available, but can’t find it on Polity website.
