  (ii) If we ignore quantum mechanics, we might well conclude that not merely the Weak Principle is contingently correct but even the Strong Principle. For unless we take space to be discrete, the classical mechanical situation would seem to be summed up by the Poincaré recurrence theorem which tells us that typically we get arbitrarily close to an exact repetition, but never get to one. (See Earman 1986, p. 130.)
