And Rupert Sheldrake later in that decade with his theory of morphic resonance.

His son Merlin Sheldrake has written a book about fungi called Entangled Life which is quite sensible and doing very well. I noticed that the book was very carefully referenced with detailed end-notes, some like mini-essays with references to papers by a wide range of authors. These notes comprise about a third of the word count of the book. Unusual in a popsci book of this kind. I can't help thinking that this approach might be a reaction to Sheldrake senior's writings and the reaction to them.

OA is a nice Web site with practical information on what could be an interesting art-practice.
