HAS THE WORLD ALWAYS EXISTED?

Sum. Th. I, Q. xlix, A. 1: C.G. II, xxxiv, xxxvii

THE seventeenth point of inquiry is whether the world has always existed: and it would seem that it has.

             1. A thing never fails in that which is proper to it. Now according to Dionysius (De Coel. Hier. iv) it is proper to the divine goodness to communicate itself to the things that exist; and this was done by the creation. Since then the divine goodness always was it would seem that it has always brought creatures into being, and that consequently the world has always existed.

             2. God does not refuse a creature that which it is capable of having according to its nature. Now there are creatures the nature of which is capable of having been always, for instance, the heavens. Therefore seemingly it was granted to the heavens to have been always. But given that the heavens existed we must allow that other creatures existed as the Philosopher proves (De Coelo ii, 3). Therefore it would appear that the world has always existed. The minor premiss is proved as follows. That which is incorruptible is capable of having always been, since were it capable of being only for a certain fixed time, it would not exist for ever, and therefore would not be incorruptible. Now the heavens are incorruptible: and consequently are capable of being always.

             3. It will be replied that the heavens are not absolutely incorruptible, since they would fall away into nothingness if God did not preserve them in being.--On the contrary we must not conclude that a statement is possibly or contingently true from the fact that it would be false if the consequence were false: thus it is necessarily true that man is an animal, and yet it would be false if the consequence were false, namely that man is a substance. Consequently we must not conclude that the heavens are corruptible from the fact that they would cease to exist on the supposition that God withdrew his sustaining power from creatures.

             4. As Avicenna proves (Metaph. ix, 4) every effect in comparison with its cause is necessary, since if given the cause the effect does not follow of necessity, even when the cause is present it will be possible for the effect to follow or not. Now that which is possible does not become actual except through something actual: so that besides the aforesaid cause we shall need another cause to make the effect emerge from the potentiality whereby it was possible for it to be or not to be on the presupposition of its cause. Whence it follows that given a sufficient cause the effect follows of necessity. Now God is the sufficient cause of the world. Therefore as God always was, so also was the world.

             5. Whatsoever preceded time has always been: for eviternity did not precede time but began with time. Now the world was before time, since it was created in the first instant of time, which clearly was before time: for it is written (Gen. i, 1): In the beginning God created heaven and earth, where a gloss notes, that is in the beginning of time. Therefore the world existed from eternity.

             6. That which remains unchanged always produces the same effect, unless it be hindered. Now God is always the same according to Psalm ci, 28: Thou art always the selfsame. Since then God cannot be hindered in his action on account of the infinity of his power, it would seem that he always produces the same effect: so that as he produced the world at some time, it would seem that he always produced it from eternity.

             7. As man necessarily wills his own happiness so God necessarily wills his own goodness and whatsoever pertains to it. Now it belongs to God's goodness to bring creatures into being. Therefore God wills this of necessity, and seemingly willed to do so from eternity, even as from eternity he willed his own goodness.

             8. It may be said that it belongs to God's goodness to bring creatures into being, but not to do so from eternity.--On the contrary it is more bountiful to give quickly than tardily: and the bounty of God's goodness is infinite. Therefore seemingly he gave being to creatures from eternity.

             9. Augustine says (Confess. vii, 4): In thee to be able is to will, and to will is to do. Now God from eternity willed to create the world: otherwise he would have changed, if the will to create came to him anew. Since then there is no inability in God, it would seem that he created the world from eternity.

             10. If the world was not always, before it existed it was either possible for it to exist or it was impossible. If it was not possible, it was impossible and consequently it was necessary for it not to be: and thus it would never have been brought into being. And if it was possible for it to be, there was some potentiality in respect thereof, and consequently a subject or matter, since potentiality demands a subject. But if there was matter there was also form, since matter cannot be entirely devoid of form. Therefore there was a body composed of matter and form, and consequently the entire universe.

             11. Whatsoever becomes actual after being potential, is brought from potentiality to actuality. Hence if before the world actually existed it was possible for it to exist, we must infer that the world was brought from potentiality to actuality, and consequently that matter preceded and was eternal; so that we come to the same conclusion as before.

             12. An agent that begins to act anew is moved from potentiality to actuality; and this cannot be said of God who is utterly immovable. Therefore it would seem that he does not begin anew to act, but that he created the world from eternity.

             13. If a voluntary agent begins to do what he already willed but has not done yet, we must suppose that something has occurred to induce him to do it now, which did not induce him before, but stirs him to action as it were. But it cannot be said that before the world existed there was something besides God to offer him a fresh inducement to act. Since then he purposed from eternity to create the world (otherwise something new would have occurred to his will) it would seem that he made the world from eternity.

             14. Further, nothing besides God's goodness moves the divine will to act. Now the divine goodness is always the same. Therefore God's will also is always bent on the production of creatures, and thus he produced them from eternity.

             15. That which is always in its beginning and always in its end, never begins and never ceases, because a thing is after it has begun and before it has ceased. Now time is always in its beginning and end, because time is nothing but an instant which is the end of the past and the beginning of the future. Hence time never begins nor ends but is always: and consequently movement also and things that are subject to movement, in fact, the whole world: since there is no time without movement, nor movement without movables, nor movable things apart from the world.

             16. It will be said perhaps that the first instant of time is not the end of the past nor the last beginning of the future. --On the contrary the now of time is always considered as flowing, wherein it differs from the now of eternity: and that which flows passes from one thing to another. Consequently every now passes from a previous to a following now, and there cannot be a first or last now.

             17. Movement follows that which can be moved, and time follows movement. Now the first movable being circular has neither beginning nor end, for it is not possible to indicate the actual beginning or end of a circle. Therefore neither time nor movement has a beginning, and the same conclusion follows as above.

             18. It will be said that although a circular body has no beginning of its magnitude, it has a beginning of its duration. --On the contrary duration of movement follows the measure of magnitude, because, according to the Philosopher (Phys. iv, 11), magnitude, motion and time are mutually proportionate. Hence if there be no beginning of the magnitude of a circular body neither will there be a beginning of the magnitude of movement or of time, and consequently there will be no beginning of their duration, since their duration, especially that of time, is their magnitude.

             19. God is the cause of things by his knowledge: and knowledge connotes relation to the thing knowable. Since then relatives are by nature simultaneous, and God's knowledge is eternal, it would seem that things were produced by him from eternity.

             20. God precedes the world either in the order of nature only, or by duration. If only in the order of nature, as a cause precedes its synchronous effect, it would seem that creatures must have existed, like God, from eternity. And if he precede the world in duration, there must have been a duration prior to that of the world, so as to constitute a before and after in duration; and this implies time. Therefore the world was preceded by time and consequently by movement and movable things: and we come to the same conclusion as before.

             21. Augustine (De Trin. v, 16) says: I dare not assert that God was not Lord from eternity. Now so long as he was Lord he had creatures for his subjects. Therefore we must not assert that creatures are not from eternity.

             22. God was able to create the world before he created it, else he were impotent. Likewise he knew that he could, else he were ignorant. And apparently he willed, else he were envious. Therefore it would seem that he did not wait to begin creating creatures.

             23. Whatsoever is finite can be communicated to a creature. Now eternity is something finite: else nothing could extend beyond it, and yet it is written (Exod. xv, 18): The Lord shall reign for eternity and beyond. Therefore one would infer that a creature is capable of being eternal, and that it was becoming to the divine goodness to produce creatures from eternity.

             24. Whatsoever has a beginning has a measure of its duration. Now time cannot have a measure of its duration: for it cannot be measured by eternity, since then it would have been always: nor by eviternity, since then it would last for ever: nor by time, since nothing is its own measure. Therefore time had no beginning, and consequently neither had movable things, nor the world.

             25. If time had a beginning, this was either in time or in an instant. It did not begin in an instant, for in an instant there is not yet time: nor did it begin in time, for in that case no time would precede the term of time, since before a thing begins to exist it is nothing. Consequently time had no beginning and the same conclusion follows as before.

             26. God from eternity was the cause of things: otherwise we should have to say that he was at first their potential and afterwards their actual cause; so that there would be something already in existence to reduce him from potentiality to act: and this is impossible. Now nothing is a cause unless it has an effect. Therefore the world was created by God from eternity.

             27. Truth and being are convertible: and many truths are eternal, such as that man is not an ass, and that the world was to be, and many similar truths. Therefore it would seem that many beings are from eternity, and not God alone.

             28. But it may be said that all these are true by the first truth which is God.--On the contrary, the truth of this proposition, 'The world will exist,' differs from the truth of this proposition, 'Man is not an ass,' because granted, though it is impossible, that the one is false, the other remains true. But the first truth cannot alter. Therefore these propositions are not true by the first truth.

             29. According to the Philosopher (Categor 5.) a statement is true or false according as the thing is so or not. If, then, many propositions are true from eternity, it would seem that the things signified by them have existed from eternity.

             30. With God 'to speak' and 'to make' are the same according to Psalm xxxii, 9, He spake and they were made. Now God spoke from eternity, otherwise the Son who is the Father's Word would not be co-eternal with the Father. Therefore God's work is eternal and the world was made from eternity.

             On the contrary it is said (Prov. viii, 24 seqq.) in the words of divine Wisdom: The depths were not as yet and I was already conceived, neither had the fountains of waters as yet sprung out. The mountains with their huge bulk had not as yet been established: before the hills was I brought forth. He had not yet made the earth, nor the rivers, nor the poles of the world. Therefore the poles of the world, the rivers and the earth were not always.

             Again according to Priscian, the younger in point of time are keener in point of intelligence. But keenness of intelligence is not infinite: therefore the time during which it increases is not infinite and consequently neither is the world.

             Again it is written (Job xxiv, 19): With inundation the ground by little and little is washed away. Now the earth is not infinite: so that if time were infinite the earth would by now have been wholly washed away: and this is clearly false.

             Again it is evident that God naturally preceded the world as a cause precedes its effect. But in God duration and nature are the same, therefore God preceded the world by duration, and thus the world was not always.

             I answer that we must not hesitate to hold that, as the Catholic faith teaches, the world has not always existed. This cannot be disproved by any physical demonstration.

             In order to make this clear we must observe that as we have shown in a previous question in God's works we cannot assign a necessity on the part of the material cause, nor on the part of the active power of the agent, nor on the part of the ultimate end, but only on the part of the form which is the end of the work, since if the form be presupposed it is requisite that things be such as to be fit for such and such a form. Hence we must speak of the production of this or that particular creature otherwise than of the production of the whole universe by God. When we speak of the production of a particular creature, it is possible to gather the reason why it is such and such, from some other creature, or at least from the order of the universe to which every creature is ordained, as a part to the form of the whole. But when we speak of the production of the whole universe, we cannot point to any other creature as being the reason why the universe is such and such. Wherefore since neither on the part of the divine power which is infinite, nor of the divine goodness which stands not in need of creatures, can a reason be assigned for the particular disposition of the universe: this reason must be found in the mere will of the Creator: so that if it be asked why the heavens are of such and such a size, no other reason can be given except that their maker willed it so. For this reason too, as Rabbi Moses says, Holy Writ exhorts us to consider the heavenly bodies, since we gather from their disposition how all things are subject to the will and providence of a Creator. For no reason can be given for the distance of this star from that one, or for any other dispositions that we observe in the heavens, save the ordinance of divine wisdom: wherefore it is written (Isa. xl, 26): Lift up your eyes on high and see who hath created these things. Nor does it matter if someone say that the distance in question results from the nature of the heavens or heavenly bodies, even as a certain quantity is appointed to every natural thing, because just as the divine power is not confined to this rather than to that quantity, so is it not confined to a nature that requires one particular quantity rather than to a nature that requires another quantity. Consequently it makes no difference whether it be a question of quantity or of nature: although we grant that the nature of the heavens is not indifferent to any quantity in particular, and that there is no inherent possibility of the heavens having any other quantity than that which they actually have. But this cannot be said of time or the duration of time. For time like place is extraneous to things: wherefore although there is no possibility in the heavens with respect to another quantity or inherent accident, yet is there a possibility with regard to place and position, since the heavens have a local movement; and with regard to time, since time ever succeeds time, even as there is succession in movement and ubiety: wherefore it cannot be said that neither time nor ubiety result from the heavens' nature, as was the case with quantity. It is clear then that the appointment of a fixed quantity of duration for the universe depends on the mere will of God, even as the appointment of a fixed quantity of dimension. Consequently we cannot come to a necessary conclusion about the duration of the universe, so as to prove demonstratively that the world has always existed.

             Some, however, through failing to observe that the universe was made by God, were unable to avoid erring in this question about the beginning of the world. Thus the earliest physicists recognised no effective cause and maintained that uncreated matter was the cause of all things, and thus they were compelled to hold that matter had always existed. For seeing that nothing brings itself from non-existence into being, that which begins to exist must be caused by something else. These asserted--either that the world was always in continual existence, because they recognised none but natural agents which being confined to one mode of action, of necessity always produced the same effects;--or that the world had an interrupted existence; thus Democritus held the world, or rather worlds, to be in a continual state of formation and destruction on account of the chance movements of atoms.

             Since, however, it seemed unreasonable that all the congruities and utilities to be found in nature should be due to chance, whereas they obtain either always or in the majority of cases: and seeing that nevertheless this would follow if there were no other cause but matter, and especially that there are some effects which cannot be sufficiently explained by the causality of matter, others like Anaxagoras posited an intellect as active cause, or like Empedocles, attraction and repulsion. Yet they did not hold these to be the active causes of the universe, but likened them to other particular agents whose activity consists in the transformation of matter from one thing into another. Consequently they were compelled to assert that matter is eternal, through not having a cause of its existence: but that the world had a beginning, because every effect of a cause which acts by movement follows its cause in duration, since such effect does not exist before the end of the movement, which end is preceded by the initial movement, co-existent with which is the agent that initiates the movement.

             Aristotle (Phys. viii, 1), observing that if it be said that the efficient cause of the world acted by movement, it would follow that one would have to proceed to infinity, since every movement must be preceded by another movement, maintained that the world has always existed. He argued not from the position that the world was made by God, but from the position that an agent which begins to act must be moved: thus considering the particular and not the universal cause. Wherefore in order to prove the eternity of the world he based his arguments on movement and the immobility of the prime mover: and hence if we consider them carefully, his arguments seem to be those of one who is arguing against a position, so that at the commencement of Phys. viii, having introduced the question of the eternity of movement, he begins by citing the opinions of Anaxagoras and Empedocles, his object being to argue against them. Those who came after Aristotle, however, considering that the whole universe was produced by God through his will and not by movement, endeavoured to prove the eternity of the world from the fact that the will does not wait to do what it intends, except on account of some new occurrence or change, even though we be compelled to imagine it in the succession of time, in that one wills to do this or that now and not sooner. Yet these fell into the same error as those mentioned before. For they considered the first agent as being like an agent which exercises its activity in time and yet acts through its will. Such an agent is not the cause of time but presupposes it: whereas God is cause even of time, since time is included in the universality of the things made by God: and therefore seeing that we are considering the production of all being by God, the fact that he made it then and not sooner does not enter the question. For this considers time as though it preceded the making instead of being conditional on the making. But if we consider the making of the universality of creatures among which time itself is included, we must consider why such and such a measure was affixed to time, and not why the making was at such and such a time. The fixing of the measure to time depends on the mere will of God, who willed that the world should not have always been, but should have a beginning, even as he willed the heavens to be neither greater nor smaller than they are.

             Reply to the First Objection. It is proper to (divine) goodness to bring things into being through the will of which it is the object. Consequently it does not follow that because the divine goodness always existed therefore things brought into being always existed, but that they were produced according to the disposition of the divine will.

             Reply to the Second Objection. The heavenly body being incorruptible is capable of always being: but no capability whether of being or of operating regards the past, but only the present or the future: since no man exercises a power over his past actions, for he cannot cause to have been done that which he has not done: but he has the power to do it now or in the future. Consequently the capability in the heavens of being always regards not the past but the future.

             Reply to the Third Objection. The fact that the heavens would return into nothingness if God ceased to uphold them does not make them corruptible simply. Seeing, however, that the preservation of the creature by God depends on God's unchangeableness, not on natural necessity (in which case it would be absolutely necessary), and is necessary solely on the supposition that God wills and has unchangeably decreed that preservation, it may be granted that the heavens are corruptible in a restricted sense, in so far as their incorruptibility is dependent on God.

             Reply to the Fourth Objection. Every effect carries a necessary relationship to its effective cause whether natural or voluntary. But we have already proved (A. 15) that God is the cause of the world not by a necessity of his nature, but by his will: wherefore it was necessary for the divine effect to follow not whenever the divine nature existed, but when the divine will decreed that it should follow, and in the very manner that he willed.

             Reply to the Fifth Objection. A thing may precede time in two ways. First, before the whole of time, and before anything belonging to time. In this way the world did not precede time, because the instant wherein the world began, though not time, is something belonging to time, not indeed a part but the starting-point of time. In another way a thing is said to precede time because it is before the completion of time: and time is not complete before the instant that is preceded by another instant: in this sense the world preceded time. It does not follow from this that the world is eternal, since the instant of time that precedes time is not eternal.

             Reply to the Sixth Objection. Since every agent produces its like, an effect must follow from an effectively operating cause, so as to bear a likeness to its cause. Now as that which proceeds from a cause that acts by its nature bears a likeness thereto in that it has a form like the form of its cause, so that which proceeds from a voluntary agent bears a likeness thereto in that it has a form like its cause, forasmuch as the effect is the reproduction of something in accordance with the will, as instanced in the work produced by the craftsman. But the will appoints not only the form of the effect but also the place, time and all other conditions thereof: so that the effect of the will follows when the will decides and not as soon as the will is. For the likeness of the effect to the will is not in the point of being but in the point of disposal by the will. Consequently, though the will remain ever the same, it does not follow that its effect should flow from it from eternity.

             Reply to the Seventh Objection. God necessarily wills his own goodness and whatsoever is necessarily connected with his goodness. Such is not the production of creatures, and consequently the objection fails.

             Reply to the Eighth Objection. Since God made creatures in order to manifest himself, it was more fitting and more to the purpose that they should be made in suchwise as to manifest him in a more becoming manner and more clearly. Now he is more clearly manifested by creatures if they be not from eternity, because this brings into greater evidence the fact that he brought them into being and that he does not need them, and that they are entirely dependent on his will.

             Reply to the Ninth Objection. God's will to create the world was eternal; not that the world should exist from eternity, but that it should be made when he actually did make it.

             Reply to the Tenth Objection. Before the world was it was possible for the world to be made, not by a passive potentiality, but by the active power of the agent.--Or we may reply that it was possible not by reason of some power, but because the terms of the proposition, 'The world exists' are not in contradiction to each other. According to the Philosopher (Metaph. v, 12) a thing may be said to be possible in this way without reference to a potentiality.

             This suffices for the Reply to the Eleventh Objection.

             Reply to the Twelfth Objection. This argument stands in the case of an agent that begins a new action, whereas God's action is eternal, since it is his substance. He is said, however, to begin to act in reference to a new effect that results from his eternal action according to the disposition of his will which is considered as the principle of his action in relation to the effect. For the effect follows from the action according to the condition of the form that is the principle of that action: even so a thing is heated by the action of the fire according to the degree of heat in the fire.

             Reply to the Thirteenth Objection. This argument considers the agent that produces its effect in time without being the cause of time: this does not apply to God as stated above (A. 15).

             Reply to the Fourteenth Objection. If movement be taken strictly God's will is not moved: but it is said to be moved, metaphorically speaking, by its object: and thus God's goodness alone moves his will, according to the saying of Augustine (Gen. ad lit. viii, 22) that God moves himself independently of place and time. Nor does it follow that creatures were produced whenever God's goodness existed, because creatures proceed from God not as though they were due or necessary to his goodness, since it does not need them, nor does he gain anything by them, but by his mere will.

             Reply to the Fifteenth Objection. Since the first succession of time was caused by movement (Phys. iv, 12) it is true that every instant is a beginning and an end of time, even as it is true that every moved thing is in a beginning and in an end of movement: so that if we suppose that movement neither always existed nor will always exist, there will be no need to say that every instant is a beginning and an end of time; for there will be an instant which will be only a beginning, and an instant which will be only an end. Hence this objection argues in a circle and consequently does not prove: but it serves the purpose of Aristotle who employs it to attack a position as we have said above. In fact, many arguments serve to rebut an opinion on account of the statements advanced by its holders, and yet in themselves are not absolute demonstrations.

             Reply to the Sixteenth Objection. An instant is indeed always considered as flowing, yet not always as flowing from one thing to another, but sometimes as only flowing from something, for example, the last instant of time, sometimes as flowing only towards something, as the first instant.

             Reply to the Seventeenth Objection. This argument does not prove that movement has always existed, but that circular movement can be always, because from mathematical principles we cannot with certainty draw conclusions about movement: hence Aristotle (Phys. viii, 8) does not infer the eternity of a movement from its being circular, but from the fact that a movement is eternal he shows that it must be circular, because no other movement can be eternal.

             This suffices for the Reply to the Eighteenth Objection.

             Reply to the Nineteenth Objection. Things knowable are related to our knowledge as God's knowledge is to creatures: because God's knowledge is the cause of creatures and things knowable are the cause of our knowledge. Wherefore even as things are knowable even without our knowing them (De Categor. 7), so is it possible for God to have knowledge without the knowable thing having existence.

             Reply to the Twentieth Objection. God does indeed precede the world by duration, not of time but of eternity, since God's existence is not measured by time. Nor was there real time before the world, but only imaginary; thus now we can imagine an infinite space of time running with eternity and preceding the beginning of time.

             Reply to the Twenty-first Objection. If the relation of lordship be regarded as consequent to the action whereby God actually governs creatures, then God was not Lord from eternity. But if it be regarded as consequent to the power of governing, then it belongs to God from eternity. Nor does it follow that creatures must have existed from eternity except potentially.

             Reply to the Twenty-second Objection. This is Augustine's argument (Contra Maxim. ii, 7, 8, 23) to prove that the Son is co-eternal and co-equal with the Father. But this argument is not applicable to the world, because as the Son's nature is the same as the Father's it requires to be co-eternal and co-equal with the Father's, otherwise were this denied him it would savour of envy. The nature of the creature, however, does not require this: and consequently the comparison fails.

             Reply to the Twenty-third Objection. The Greek text reads: The Lord shall reign for age upon age and beyond: and Origen, as quoted by a gloss, says that by age we are to understand the space of one generation the limits of which are known to us: by age upon age we are to understand an immense space of time which has an end, yet unknown to us: and that God's reign will extend even beyond this. Hence 'eternity' here means the duration of time. Anselm, however (Proslog. xix, xx), takes eternity to mean eviternity, which has no end: and yet God is said to reign beyond it, because in the first place eviternal things can be thought of as non-existent; secondly, because they would not be if God ceased to uphold them, so that of themselves they do not exist: thirdly, because they have not their whole existence at once, but are subject to successive change.

             Reply to the Twenty-fourth Objection. That which has a beginning must have a measure of its duration in so far as it begins through movement. But time does not begin thus by creation, wherefore the argument does not prove. However, it may be said that every measure is measured by itself within its own genus: thus a line is measured by a line, and time by time.

             Reply to the Twenty-fifth Objection. Time is not like permanent things which have their whole substance at once: so that there is no need for the whole of time to exist as soon as it begins. Consequently it is not untrue that time begins in an instant.

             Reply to the Twenty-sixth Objection. God's action is eternal, but its effect is not, as we have stated above: hence though God was not always cause, inasmuch as his effect was not always, it does not follow that he was not cause potentially, since his action was always, unless we refer the potentiality to the effect.

             Reply to the Twenty-seventh Objection. According to the Philosopher (Metaph. vi, 4) truth is in the mind, not in things, for it is the equation of thought and thing. Wherefore whatsoever has been from eternity has been true by the truth of the divine mind, which truth is eternal.

             Reply to the Twenty-eighth Objection. Whatsoever things are said to be true from eternity do not vary in their truth, but are true by the one same truth of the divine mind, with reference nevertheless to various things as future in their own being: so that we are able to indicate a certain distinction in that truth resulting from their various relations.

             Reply to the Twenty-ninth Objection. The saying of the Philosopher refers to our mental or oral statements, since the truth of our thought or words is caused by things already evident: whereas the truth of the divine mind is the cause of things.

             Reply to the Thirtieth Objection. On the part of God there is no difference between 'to make' and 'to speak,' for God's action is not an accident but his substance: nevertheless 'to make' connotes the effect actually existing in its own nature, whereas 'to speak' does not.

             The arguments on the contrary side, although they prove what is true, are not demonstrative except the first which is based on authority. The argument taken from the growth of intelligence in the course of time, does not prove that time must have had a beginning: since possibly the study of the sciences may have been frequently interrupted, and subsequently taken up anew after a long interval, as the Philosopher observes. Again the soil is not so much eaten away by erosion on one part of the earth's surface without a corresponding increase taking place elsewhere through the combination of the elements. And the duration of God, although it be identified with the divine nature in reality, differs therefrom logically: so that it does not follow that God preceded the world in duration from the fact that he preceded it naturally.
