XX. These things, then, may be said by us with respect to the argument that the inequalities of the surface of the earth are no proof of the world having been created and being liable to destruction; but with respect to that argument which was endeavoured to be established by the diminution of the sea, we may reasonably adduce this statement in opposition to it: “Do not look only at the islands which have risen up out of the sea, nor at any portions of land which, having been formerly buried by the waters, have in subsequent times become dry land; for obstinate contention is very unfavourable to the consideration of natural philosophy, which considers the search after truth to be the chief object of rational desire; but look rather at the contrary effects: consider how many districts on the main-land, not only such as were near the coast, but even such as were completely inland, have been swallowed up by the waters; and consider how great a portion of land has become sea and is now sailed over by innumerable ships.” Are you ignorant of the celebrated account which is given of that most sacred Sicilian strait, which in old times joined Sicily to the continent of Italy? and where vast seas on each side being excited by violent storms met together, coming from opposite directions, the land between them was overwhelmed and broken away; from which circumstance the city built in the neighbourhood was called Rhegium, {19}{rheµgion, from rhoµgnymi, “to break.”} and the result was quite different from what any one would have expected; for the seas which had formerly been separated now flowed together and were united in one expanse; and the land which had previously united was now separated into two portions by the strait which intersected it, in consequence of which Sicily, which had previously formed a part of the mainland, was now compelled to be an island. XXI. And it is said that many other cities also have disappeared, having been swallowed up by the sea which overwhelmed them; since they speak of three in Peloponnesus-
“Aegira and fair Bura’s walls,
And Helica’s lofty halls,
And many a once renowned town,
With wreck and seaweed overgrown,”
as having been formerly prosperous, but now overwhelmed by the violent influx of the sea. And the island of Atalantes which was greater than Africa and Asia, as Plato says in the Timaeus, in one day and night was overwhelmed beneath the sea in consequence of an extraordinary earthquake and inundation and suddenly disappeared, becoming sea, not indeed navigable, but full of gulfs and eddies. Therefore that imaginary and fictitious diminution of the sea has no connection with the destruction or durability of the world; for in fact it appears to recede indeed from some parts, but to rise higher in others; and it would have been proper rather not to look at only one of these results but at both together, and so to form one’s opinion, since in all the disputed questions which arise in human life, a wise and honest judge will not deliver his opinion before he has heard the arguments of the advocates on both sides.
XXII. And as for the third argument, it is convicted by itself, as being derived only from an unsound system of questioning proceeding from the assertions originally made; for in truth it does not necessarily follow that a thing, all the parts of which are liable to corruption, is likewise perishable itself; but this is only inevitably true of that thing of which all the parts are perishable when taken collectively and together in the same place and at the same time, since in the case of a person who has the tip of his finger cut off, he is not disabled from living, but if he had the whole collection of all his parts and limbs cut off at once, he would die immediately. Therefore in the same manner, if all the elements of the world together were all to disappear at one and the same moment, then it would be necessary to admit that the world was liable to corruption and destruction; but if each of these elements separately only changes its nature so as to assimilate to that of its nature, it is then rendered immortal rather than destroyed, according to the philosophical statement of the tragic poet-
