Of Man's Last End

Of Man's Last End — St. Thomas Aquinas asks: Whether it belongs to man to act for an end?; Whether it is proper to the rational nature to act for an end?; Whether human acts are specified by their end?; Whether there is one last end of human life?; Whether one man can have several last ends?; Whether man will all, whatsoever he wills, for the last end?; Whether all men have the same last end?; Whether other creatures concur in that last end?.

In this matter we shall consider first the last end of human life; and secondly, those things by means of which man may advance towards this end, or stray from the path: for the end is the rule of whatever is ordained to the end. And since the last end of human life is stated to be happiness, we must consider (1) the last end in general; (2) happiness.

Under the first head there are eight points of inquiry:

Article 1: Whether it belongs to man to act for an end?

All things contained in a genus are derived from the principle of that genus. Now the end is the principle in human operations, as the Philosopher states (Phys. ii, 9). Therefore it belongs to man to do everything for an end.

Of actions done by man those alone are properly called "human," which are proper to man as man. Now man differs from irrational animals in this, that he is master of his actions. Wherefore those actions alone are properly called human, of which man is master. Now man is master of his actions through his reason and will; whence, too, the free-will is defined as "the faculty and will of reason." Therefore those actions are properly called human which proceed from a deliberate will. And if any other actions are found in man, they can be called actions "of a man," but not properly "human" actions, since they are not proper to man as man. Now it is clear that whatever actions proceed from a power, are caused by that power in accordance with the nature of its object. But the object of the will is the end and the good. Therefore all human actions must be for an end.

Article 2: Whether it is proper to the rational nature to act for an end?

The Philosopher proves (Phys. ii, 5) that "not only mind but also nature acts for an end."

Every agent, of necessity, acts for an end. For if, in a number of causes ordained to one another, the first be removed, the others must, of necessity, be removed also. Now the first of all causes is the final cause. The reason of which is that matter does not receive form, save in so far as it is moved by an agent; for nothing reduces itself from potentiality to act. But an agent does not move except out of intention for an end. For if the agent were not determinate to some particular effect, it would not do one thing rather than another: consequently in order that it produce a determinate effect, it must, of necessity, be determined to some certain one, which has the nature of an end. And just as this determination is effected, in the rational nature, by the "rational appetite," which is called the will; so, in other things, it is caused by their natural inclination, which is called the "natural appetite."

Nevertheless it must be observed that a thing tends to an end, by its action or movement, in two ways: first, as a thing, moving itself to the end, as man; secondly, as a thing moved by another to the end, as an arrow tends to a determinate end through being moved by the archer who directs his action to the end. Therefore those things that are possessed of reason, move themselves to an end; because they have dominion over their actions through their free-will, which is the "faculty of will and reason." But those things that lack reason tend to an end, by natural inclination, as being moved by another and not by themselves; since they do not know the nature of an end as such, and consequently cannot ordain anything to an end, but can be ordained to an end only by another. For the entire irrational nature is in comparison to God as an instrument to the principal agent, as stated above (; ). Consequently it is proper to the rational nature to tend to an end, as directing [agens] and leading itself to the end: whereas it is proper to the irrational nature to tend to an end, as directed or led by another, whether it apprehend the end, as do irrational animals, or do not apprehend it, as is the case of those things which are altogether void of knowledge.

Article 3: Whether human acts are specified by their end?

Augustine says (De Mor. Eccl. et Manich. ii, 13): "According as their end is worthy of blame or praise so are our deeds worthy of blame or praise."

Each thing receives its species in respect of an act and not in respect of potentiality; wherefore things composed of matter and form are established in their respective species by their own forms. And this is also to be observed in proper movements. For since movements are, in a way, divided into action and passion, each of these receives its species from an act; action indeed from the act which is the principle of acting, and passion from the act which is the terminus of the movement. Wherefore heating, as an action, is nothing else than a certain movement proceeding from heat, while heating as a passion is nothing else than a movement towards heat: and it is the definition that shows the specific nature. And either way, human acts, whether they be considered as actions, or as passions, receive their species from the end. For human acts can be considered in both ways, since man moves himself, and is moved by himself. Now it has been stated above () that acts are called human, inasmuch as they proceed from a deliberate will. Now the object of the will is the good and the end. And hence it is clear that the principle of human acts, in so far as they are human, is the end. In like manner it is their terminus: for the human act terminates at that which the will intends as the end; thus in natural agents the form of the thing generated is conformed to the form of the generator. And since, as Ambrose says (Prolog. super Luc.) "morality is said properly of man," moral acts properly speaking receive their species from the end, for moral acts are the same as human acts.

Article 4: Whether there is one last end of human life?

The Philosopher says (Metaph. ii, 2) that "to suppose a thing to be indefinite is to deny that it is good." But the good is that which has the nature of an end. Therefore it is contrary to the nature of an end to proceed indefinitely. Therefore it is necessary to fix one last end.

Absolutely speaking, it is not possible to proceed indefinitely in the matter of ends, from any point of view. For in whatsoever things there is an essential order of one to another, if the first be removed, those that are ordained to the first, must of necessity be removed also. Wherefore the Philosopher proves (Phys. viii, 5) that we cannot proceed to infinitude in causes of movement, because then there would be no first mover, without which neither can the others move, since they move only through being moved by the first mover. Now there is to be observed a twofold order in ends---the order of intention and the order of execution: and in either of these orders there must be something first. For that which is first in the order of intention, is the principle, as it were, moving the appetite; consequently, if you remove this principle, there will be nothing to move the appetite. On the other hand, the principle in execution is that wherein operation has its beginning; and if this principle be taken away, no one will begin to work. Now the principle in the intention is the last end; while the principle in execution is the first of the things which are ordained to the end. Consequently, on neither side is it possible to go to infinity since if there were no last end, nothing would be desired, nor would any action have its term, nor would the intention of the agent be at rest; while if there is no first thing among those that are ordained to the end, none would begin to work at anything, and counsel would have no term, but would continue indefinitely.

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.

Article 5: Whether one man can have several last ends?

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 Mat. 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.

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 (), 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.

Article 6: Whether man will all, whatsoever he wills, for the last end?

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."

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.

Article 7: Whether all men have the same last end?

Augustine says (De Trin. xiii, 3) that all men agree in desiring the last end, which is happiness.

We can speak of the last end in two ways: first, considering only the aspect of last end; secondly, considering the thing in which the aspect of last end is realized. So, then, as to the aspect of last end, all agree in desiring the last end: since all desire the fulfilment of their perfection, and it is precisely this fulfilment in which the last end consists, as stated above (). But as to the thing in which this aspect is realized, all men are not agreed as to their last end: since some desire riches as their consummate good; some, pleasure; others, something else. Thus to every taste the sweet is pleasant but to some, the sweetness of wine is most pleasant, to others, the sweetness of honey, or of something similar. Yet that sweet is absolutely the best of all pleasant things, in which he who has the best taste takes most pleasure. In like manner that good is most complete which the man with well disposed affections desires for his last end.

Article 8: Whether other creatures concur in that last end?

man's last end is happiness; which all men desire, as Augustine says (De Trin. xiii, 3,4). But "happiness is not possible for animals bereft of reason," as Augustine says (QQ. 83, qu. 5). Therefore other things do not concur in man's last end.

As the Philosopher says (Phys. ii, 2), the end is twofold---the end "for which" and the end "by which"; viz. the thing itself in which is found the aspect of good, and the use or acquisition of that thing. Thus we say that the end of the movement of a weighty body is either a lower place as "thing," or to be in a lower place, as "use"; and the end of the miser is money as "thing," or possession of money as "use."

If, therefore, we speak of man's last end as of the thing which is the end, thus all other things concur in man's last end, since God is the last end of man and of all other things. If, however, we speak of man's last end, as of the acquisition of the end, then irrational creatures do not concur with man in this end. For man and other rational creatures attain to their last end by knowing and loving God: this is not possible to other creatures, which acquire their last end, in so far as they share in the Divine likeness, inasmuch as they are, or live, or even know.

Hence it is evident how the objections are solved: since happiness means the acquisition of the last end.
