Coincidence may be described as the chance encounter of two unrelated causal chains which-miraculously, it seems-merge into a significant event. It provides the neatest paradigm of the bisociation of previously separate contexts, engineered by fate. Coincidences are puns of destiny. In the pun, two strings of thought are tangled into one acoustic knot; in the coincidental happening, two strings of events are knitted together by invisible hands.
Man's destiny was no longer determined from 'above' by a super-human wisdom and will, but from 'below' by the sub-human agencies of glands, genes, atoms, or waves of probability. ...they could determine his fate, but could provide him with no moral guidance, no values and meaning. A puppet of the Gods is a tragic figure, a puppet suspended on his chromosomes is merely grotesque.
Space-ships and time machines are no escape from the human condition. Let Othello subject Desdemona to a lie-detector test; his jealousy will still blind him to the evidence. Let Oedipus triumph over gravity; he won't triumph over his fate.
