The Letters of William James, Vol. 1 · William James
W. J.
I don't know whether you have heard of the London "Society for Psychical Research," which is seriously and laboriously investigating all sorts of "supernatural" matters, clairvoyance, apparitions, etc. I don't know what you think of such work; but I think that the present condition of opinion regarding it is scandalous, there being a mass of testimony, or apparent testimony, about such things, at which the only men capable of a critical judgment--men of scientific education--will not even look. We have founded a similar society here within the year,--some of us thought that the publications of the London society deserved at least to be treated as if worthy of experimental disproof,--and although work advances very slowly owing to the small amount of disposable time on the part of the members, who are all very busy men, we have already stumbled on some rather inexplicable facts out of which something may come. It is a field in which the sources of deception are extremely numerous. But I believe there is no source of deception in the investigation of nature which can compare with a fixed belief that certain kinds of phenomenon are _impossible_.
