Those are themes for thought experiments more than things the author defends (as one would expect with a foreword from Martin Gardner who was a strong skeptic):

> This, finally, is the essence of synchronicity: the world we live in is filled with harmonies and coincidences that have no explanation in terms of cause and effect. It is fruitless to seek after hidden forces and occult powers. The world is a given — it is just as it is, full of cause and effect, full of synchronicity. > > Some people have taken these new developments to mean that such psychic feats as telepathy and psychokinesis are now firmly established scientific realities. This is not correct.
