There are journeys from which for all practical purposes it is not possible to arrive anywhere except perhaps, after considerable stress, the place where you started from. The value of such journeys is not related to their length, nor even to their difficulty, though they can be very long and extraordinarily difficult. It lies rather in the fact of having set out in the hopeless hope of discovering something, but most of all in what we find on the way, even if it is on the way to nowhere.
