The issue of retrodiction in Bohm's theory: Y. Aharonov and D. Albert
Bohm's pathbreaking hidden variable theory of 1952 1 is often accused of artificiality and inelegance, and doubtless it is guilty of both. But to make such accusations, and to leave it at that, is to entirely miss the point. What Bohm was after in his theory was not elegance and not naturalness; Bohm's intentions were simply to produce a theory which, whatever its other characteristics, had logically clear foundations. It is for that clarity which Bohm's theory is highly and rightly praised.
