FOURTH ARTICLE [I, Q. 97, Art. 4]
Whether in the State of Innocence Man Would Have Acquired Immortality by the Tree of Life?
Objection 1: It would seem that the tree of life could not be the cause of immortality. For nothing can act beyond its own species; as an effect does not exceed its cause. But the tree of life was corruptible, otherwise it could not be taken as food; since food is changed into the substance of the thing nourished. Therefore the tree of life could not give incorruptibility or immortality.
Obj. 2: Further, effects caused by the forces of plants and other natural agencies are natural. If therefore the tree of life caused immortality, this would have been natural immortality.
Obj. 3: Further, this would seem to be reduced to the ancient fable, that the G.o.ds, by eating a certain food, became immortal; which the Philosopher ridicules (Metaph. iii, Did. ii, 4).
_On the contrary,_ It is written (Gen. 3:22): ”Lest perhaps he put forth his hand, and take of the tree of life, and eat, and live for ever.” Further, Augustine says (QQ. Vet. et Nov. Test. qu. 19 [*Work of an anonymous author], among the supposit.i.tious works of St.
Augustine): ”A taste of the tree of life warded off corruption of the body; and even after sin man would have remained immortal, had he been allowed to eat of the tree of life.”
_I answer that,_ The tree of life in a certain degree was the cause of immortality, but not absolutely. To understand this, we must observe that in the primitive state man possessed, for the preservation of life, two remedies, against two defects. One of these defects was the lost of humidity by the action of natural heat, which acts as the soul's instrument: as a remedy against such loss man was provided with food, taken from the other trees of paradise, as now we are provided with the food, which we take for the same purpose. The second defect, as the Philosopher says (De Gener. i, 5), arises from the fact that the humor which is caused from extraneous sources, being added to the humor already existing, lessens the specific active power: as water added to wine takes at first the taste of wine, then, as more water is added, the strength of the wine is diminished, till the wine becomes watery. In like manner, we may observe that at first the active force of the species is so strong that it is able to transform so much of the food as is required to replace the lost tissue, as well as what suffices for growth; later on, however, the a.s.similated food does not suffice for growth, but only replaces what is lost. Last of all, in old age, it does not suffice even for this purpose; whereupon the body declines, and finally dies from natural causes. Against this defect man was provided with a remedy in the tree of life; for its effect was to strengthen the force of the species against the weakness resulting from the admixture of extraneous nutriment. Wherefore Augustine says (De Civ. Dei xiv, 26): ”Man had food to appease his hunger, drink to slake his thirst; and the tree of life to banish the breaking up of old age”; and (QQ. Vet. et Nov. Test. qu. 19 [*Work of an anonymous author], among the supposit.i.tious works of St. Augustine) ”The tree of life, like a drug, warded off all bodily corruption.”
Yet it did not absolutely cause immortality; for neither was the soul's intrinsic power of preserving the body due to the tree of life, nor was it of such efficiency as to give the body a disposition to immortality, whereby it might become indissoluble; which is clear from the fact that every bodily power is finite; so the power of the tree of life could not go so far as to give the body the prerogative of living for an infinite time, but only for a definite time. For it is manifest that the greater a force is, the more durable is its effect; therefore, since the power of the tree of life was finite, man's life was to be preserved for a definite time by partaking of it once; and when that time had elapsed, man was to be either transferred to a spiritual life, or had need to eat once more of the tree of life.
From this the replies to the objections clearly appear. For the first proves that the tree of life did not absolutely cause immortality; while the others show that it caused incorruption by warding off corruption, according to the explanation above given.

QUESTION 98
OF THE PRESERVATION OF THE SPECIES (In Two Articles)
We next consider what belongs to the preservation of the species; and, first, of generation; secondly, of the state of the offspring. Under the first head there are two points of inquiry:
(1) Whether in the state of innocence there would have been generation?
(2) Whether generation would have been through coition?

FIRST ARTICLE [Q. 98, Art. 1]
Whether in the State of Innocence Generation Existed?
Objection 1: It would seem there would have been no generation in the state of innocence. For, as stated in _Phys._ v, 5, ”corruption is contrary to generation.” But contraries affect the same subject: also there would have been no corruption in the state of innocence.
Therefore neither would there have been generation.
Obj. 2: Further, the object of generation is the preservation in the species of that which is corruptible in the individual. Wherefore there is no generation in those individual things which last for ever. But in the state of innocence man would have lived for ever.
Therefore in the state of innocence there would have been no generation.
Obj. 3: Further, by generation man is multiplied. But the multiplication of masters requires the division of property, to avoid confusion of masters.h.i.+p. Therefore, since man was made master of the animals, it would have been necessary to make a division of rights when the human race increased by generation. This is against the natural law, according to which all things are in common, as Isidore says (Etym. v, 4). Therefore there would have been no generation in the state of innocence.
_On the contrary,_ It is written (Gen. 1:28): ”Increase and multiply, and fill the earth.” But this increase could not come about save by generation, since the original number of mankind was two only.
Therefore there would have been generation in the state of innocence.
_I answer that,_ In the state of innocence there would have been generation of offspring for the multiplication of the human race; otherwise man's sin would have been very necessary, for such a great blessing to be its result. We must, therefore, observe that man, by his nature, is established, as it were, midway between corruptible and incorruptible creatures, his soul being naturally incorruptible, while his body is naturally corruptible. We must also observe that nature's purpose appears to be different as regards corruptible and incorruptible things. For that seems to be the direct purpose of nature, which is invariable and perpetual; while what is only for a time is seemingly not the chief purpose of nature, but as it were, subordinate to something else; otherwise, when it ceased to exist, nature's purpose would become void.
Therefore, since in things corruptible none is everlasting and permanent except the species, it follows that the chief purpose of nature is the good of the species; for the preservation of which natural generation is ordained. On the other hand, incorruptible substances survive, not only in the species, but also in the individual; wherefore even the individuals are included in the chief purpose of nature.
Hence it belongs to man to beget offspring, on the part of the naturally corruptible body. But on the part of the soul, which is incorruptible, it is fitting that the mult.i.tude of individuals should be the direct purpose of nature, or rather of the Author of nature, Who alone is the Creator of the human soul. Wherefore, to provide for the multiplication of the human race, He established the begetting of offspring even in the state of innocence.
