Physical and Psychical Research. An Analysis of Belief

The blurb on the dust-cover of this book claims that it states an important new principle and, hence, that it is important. It aims at integrating in mathematical terms, the physical and psychological sides of science, for which purpose it includes a purely mathematical appendix on the "reversed loop". Presumably, there are people who are able to see how the writers work out their thesis. But to do so one would have to be very well up, both in psychology, parapsychology and mathematics, quite apart from the turbidity of the language itself. As it is, the book can scarcely claim to succeed.
