[125] But we must now proceed to consider the question which we postponed till the present time. What sort of a part of the earth is that, that we may begin from this, whether it is greater or less, that is not dissolved by time? Do not the very hardest and strongest stones become hard and decayed through the weakness of their conformation (and this conformation is a sort of course of a highly strained spirit, a bond not indissoluble, but only very difficult to unloose), in consequence of which they are broken up and made fluid, so that they are dissolved first of all into a thin dust, and afterwards are wholly wasted away and destroyed? Again, if the water were never agitated by the winds, but were left immoveable for ever, would it not from inaction and tranquillity become dead? at all events it is changed by such stagnation, and becomes very foetid and foul-smelling, like an animal deprived of life.
