For the sake of this explanation people deny the findings of parapsychology outright, either for philosophical reasons or from intellectual laziness. This can hardly be considered a scientifically responsible attitude, even though it is a popular way out of a quite extraordinary intellectual difficulty. To assess the psychic phenomenon, we have to take account of all the other phenomena that come with it, and accordingly we can no longer practice any psychology that ignores the existence of the unconscious or of parapsychology.
