Rupert Sheldrake riffs on a theme. He takes his area of specialist knowledge and extrapolates into what-ifs. For some reason that approach is anathema, and critics imagine he's making a statement rather than inviting a discourse on the possibilities. Materialism invites reappraisal, but only if it leaves all the furniture intact. You can move one plate at a time, but Sheldrake offers complete redecoration and has a skip outback to remove the collected junk of ages. He's just too near the bone for people heavily invested in the physical architecture.
