ABSTRACT
For some years now I have been trying to point out just why I believe that psychical research, with the establishment of ESP as a reality, must have a profound effect upon biological theory. I surprised many of my colleagues when I introduced the subject of telepathy into my Presidential Address to the Zoology Section of the British Association at its meeting in Newcastle in 1949. ‘It is, perhaps, unorthodox,’ I said ‘for a zoologist to introduce such a topic, but I do so for a reason. If telepathy has been established, as I believe it has, then such a revolutionary discovery should make us keep our minds open to the possibility that there may be so much more in living things and their evolution than our science has hitherto led us to expect.’ In the short time that I was then able to devote to the subject I failed, I think, to convey what I really had in mind.
