Thomas Aquinas - Summa Theologica, Part I-II (Pars Prima Secundae)

On the other hand, nothing hinders infinity from being in things that are ordained to one another not essentially but accidentally; for accidental causes are indeterminate. And in this way it happens that there is an accidental infinity of ends, and of things ordained to the end.

Reply Obj. 1: The very nature of good is that something flows from it, but not that it flows from something else. Since, therefore, good has the nature of end, and the first good is the last end, this argument does not prove that there is no last end; but that from the end, already supposed, we may proceed downwards indefinitely towards those things that are ordained to the end. And this would be true if we considered but the power of the First Good, which is infinite. But, since the First Good diffuses itself according to the intellect, to which it is proper to flow forth into its effects according to a certain fixed form; it follows that there is a certain measure to the flow of good things from the First Good from Which all other goods share the power of diffusion. Consequently the diffusion of goods does not proceed indefinitely but, as it is written (Wis. 11:21), God disposes all things "in number, weight and measure."

Reply Obj. 2: In things which are of themselves, reason begins from principles that are known naturally, and advances to some term. Wherefore the Philosopher proves (Poster. i, 3) that there is no infinite process in demonstrations, because there we find a process of things having an essential, not an accidental, connection with one another. But in those things which are accidentally connected, nothing hinders the reason from proceeding indefinitely. Now it is accidental to a stated quantity or number, as such, that quantity or unity be added to it. Wherefore in such like things nothing hinders the reason from an indefinite process.

Reply Obj. 3: This multiplication of acts of the will reacting on itself, is accidental to the order of ends. This is clear from the fact that in regard to one and the same end, the will reacts on itself indifferently once or several times. ________________________

FIFTH ARTICLE [I-II, Q. 1, Art. 5]

Whether One Man Can Have Several Last Ends?

Objection 1: It would seem possible for one man's will to be directed at the same time to several things, as last ends. For Augustine says (De Civ. Dei xix, 1) that some held man's last end to consist in four things, viz. "in pleasure, repose, the gifts of nature, and virtue." But these are clearly more than one thing. Therefore one man can place the last end of his will in many things.

Obj. 2: Further, things not in opposition to one another do not exclude one another. Now there are many things which are not in opposition to one another. Therefore the supposition that one thing is the last end of the will does not exclude others.

Obj. 3: Further, by the fact that it places its last end in one thing, the will does not lose its freedom. But before it placed its last end in that thing, e.g. pleasure, it could place it in something else, e.g. riches. Therefore even after having placed his last end in pleasure, a man can at the same time place his last end in riches. Therefore it is possible for one man's will to be directed at the same time to several things, as last ends.

On the contrary, That in which a man rests as in his last end, is master of his affections, since he takes therefrom his entire rule of life. Hence of gluttons it is written (Phil. 3:19): "Whose god is their belly": viz. because they place their last end in the pleasures of the belly. Now according to Matt. 6:24, "No man can serve two masters," such, namely, as are not ordained to one another. Therefore it is impossible for one man to have several last ends not ordained to one another.

I answer that, It is impossible for one man's will to be directed at the same time to diverse things, as last ends. Three reasons may be assigned for this. First, because, since everything desires its own perfection, a man desires for his ultimate end, that which he desires as his perfect and crowning good. Hence Augustine (De Civ. Dei xix, 1): "In speaking of the end of good we mean now, not that it passes away so as to be no more, but that it is perfected so as to be complete." It is therefore necessary for the last end so to fill man's appetite, that nothing is left besides it for man to desire. Which is not possible, if something else be required for his perfection. Consequently it is not possible for the appetite so to tend to two things, as though each were its perfect good.

The second reason is because, just as in the process of reasoning, the principle is that which is naturally known, so in the process of the rational appetite, i.e. the will, the principle needs to be that which is naturally desired. Now this must needs be one: since nature tends to one thing only. But the principle in the process of the rational appetite is the last end. Therefore that to which the will tends, as to its last end, is one.

The third reason is because, since voluntary actions receive their species from the end, as stated above (A. 3), they must needs receive their genus from the last end, which is common to them all: just as natural things are placed in a genus according to a common form. Since, then, all things that can be desired by the will, belong, as such, to one genus, the last end must needs be one. And all the more because in every genus there is one first principle; and the last end has the nature of a first principle, as stated above. Now as the last end of man, simply as man, is to the whole human race, so is the last end of any individual man to that individual. Therefore, just as of all men there is naturally one last end, so the will of an individual man must be fixed on one last end.

Reply Obj. 1: All these several objects were considered as one perfect good resulting therefrom, by those who placed in them the last end.

Reply Obj. 2: Although it is possible to find several things which are not in opposition to one another, yet it is contrary to a thing's perfect good, that anything besides be required for that thing's perfection.

Reply Obj. 3: The power of the will does not extend to making opposites exist at the same time. Which would be the case were it to tend to several diverse objects as last ends, as has been shown above (ad 2). ________________________

SIXTH ARTICLE [I-II, Q. 1, Art. 6]

Whether Man Wills All, Whatsoever He Wills, for the Last End?

Objection 1: It would seem that man does not will all, whatsoever he wills, for the last end. For things ordained to the last end are said to be serious matter, as being useful. But jests are foreign to serious matter. Therefore what man does in jest, he ordains not to the last end.

Obj. 2: Further, the Philosopher says at the beginning of his

Metaphysics (i. 2) that speculative science is sought for its own sake.

Now it cannot be said that each speculative science is the last end.

Therefore man does not desire all, whatsoever he desires, for the last

end.

Obj. 3: Further, whosoever ordains something to an end, thinks of that end. But man does not always think of the last end in all that he desires or does. Therefore man neither desires nor does all for the last end.

On the contrary, Augustine says (De Civ. Dei xix, 1): "That is the end of our good, for the sake of which we love other things, whereas we love it for its own sake."

I answer that, Man must, of necessity, desire all, whatsoever he desires, for the last end. This is evident for two reasons. First, because whatever man desires, he desires it under the aspect of good. And if he desire it, not as his perfect good, which is the last end, he must, of necessity, desire it as tending to the perfect good, because the beginning of anything is always ordained to its completion; as is clearly the case in effects both of nature and of art. Wherefore every beginning of perfection is ordained to complete perfection which is achieved through the last end. Secondly, because the last end stands in the same relation in moving the appetite, as the first mover in other movements. Now it is clear that secondary moving causes do not move save inasmuch as they are moved by the first mover. Therefore secondary objects of the appetite do not move the appetite, except as ordained to the first object of the appetite, which is the last end.
