A short book – only 105 pages. An old book – written in 1906. A fascinating book – in a time when these sort of ideas are being resurrected by the likes of Rupert Sheldrake and his morphic fields this is a real insight into a way of thinking that was seemingly abandoned – at least by mainstream thought – for much of the 20th Century. Proves once again that it is often wrong to assume that “no one has thought of this before” about ANY subject.
