De Aeternitate Mundi

Heraclitus therefore spoke very correctly when he said that, "Water was the death of the soul, and earth the death of water." For thinking that the breath was the soul, he indicates, by this figurative and enigmatical expression, that the end of air is the production of water, and again that the end of water is the production of earth; and when he speaks of death he does not mean utter destruction, but a change into some other element;

that equalised proportion of the elements which is attempered by itself being thus preserved eternal and uninjured, as is not only probable but absolutely inevitable; since what is unequal is essentially unjust, and injustice is the offspring of wickedness, and wickedness is banished from the

But some of those persons who have fancied that the world is everlasting, inventing a variety of new arguments, employ also such a system of reasoning as this to establish their point: they affirm that there are four principal manners in which corruption is brought about, addition, taking away, transposition, and alteration; accordingly, the number two is by the addition of the unit corrupted so as to become the number three, and no longer remains the number two; and the number four by the taking away of the unit is corrupted so as to become the number three; again, by transposition the letter Z becomes the letter H when the parallel lines which were previously horizontal = are placed perpendicularly II, and when the line which did before pass upwards I, so as to connect the two is now made horizontal, and still extended between them so as to join them. And by alteration the word οἶνος, wine, becomes ὄξος, vinegar.

But of the manner of corruption thus mentioned there is not one which is in the least degree whatever applicable to the world, since otherwise what could we say? Could we affirm that anything is added to the world so as to cause its destruction? But there is nothing whatever outside of the world which is not a portion of it as the whole, for everything is surrounded, and contained, and mastered by it. Again, can we say that anything is taken from the world so as to have that effect? In the first place that which would be taken away would again be a world of smaller dimensions than the existing one, and in the second place it is impossible that any body could be separated from the composite fabric of the whole world so as to be completely dispersed.

Again, are we to say that the constituent parts of the world are transposed? But at all events they remain in their original positions without any change of place, for never at any time shall the whole earth be raised up above the water, nor the water above the air, nor the air above the fire. But those things which are by nature heavy, namely the earth and the water, will have the middle place, the earth supporting everything like a solid

Once more: we must not imagine that the world is destroyed by alteration, for the change of any elements is equipollent, and that which is equipollent is the cause of unvarying steadiness, and of untroubled durability, inasmuch as it neither seeks any advantage itself, and is not subject to the inroads of other things which seek advantages at its expense; so that this retribution and compensation of these powers is equalized by the rules of proportion, being the produce of health and endless preservation, by all which considerations the world is demonstrated to be eternal.

Theophrastus, moreover, says that those men who attribute a beginning and destructibility to the world are deceived by four particulars of the greatest importance, the inequalities of the earth, the retreat of the sea, the dissolution of each of the parts of the universe, and the destruction of different terrestrial animals in their kinds;

and he proceeds to establish the first point thus: if the earth had never had any beginning of its creation, then there would have been no portion of it rising above the rest so as to be conspicuous, but all the mountains would have been level, and all the pieces of rising ground would have been even with the plain. For as there are such vast showers falling from heaven throughout all ages, it would be natural that of any places which were originally raised on high some would be broken down and washed away by torrents, and others would subside of their own accord and so become lowered, and that every place everywhere would be smoothed;

but now, as things are, the constant inequalities which exist, and the vast heights of many mountains, reaching up even to the sky, are so many proofs that the earth is not eternal. For otherwise, as I have said before, all the earth would long since have been rendered level from one extremity to the other by the vast rains which would have fallen from the eternal commencement of time; for it is the character of the nature of water, and especially of such as descends in a heavy fall from lofty places, to push some things away by force, and

And again, the sea, as they affirm, is already somewhat diminished, and for proof of this fact we can appeal to the most celebrated islands, Rhodes and Delos, for these were in ancient times invisible, being overwhelmed by and sunk under the sea, but by lapse of time, as the sea gradually diminished, they by slow degrees rose above it and came into sight, as the histories which are written concerning them record.
