In my essay ‘On the Nature of the Psyche,’ I considered synchronicity as a psychically conditioned relativity of space and time. Rhine’s experiments show that in relation to the psyche space and time are, so to speak, ‘elastic’ and can apparently be reduced almost to vanishing point, as though they were dependent on psychic conditions and did not exist in themselves but were only ‘postulated’ by the conscious mind.
