1 If, then, ultimate human felicity does not consist in the knowledge of God, whereby He is known in general by all, or most, men, by a sort of confused appraisal, and again, if it does not consist in the knowledge of God which is known by way of demonstration in the speculative sciences, nor in the cognition of God whereby He is known through faith, as has been shown in the foregoing; and if it is not possible in this life to reach a higher knowledge of God so as to know Him through His essence, or even in such a way that, when the other separate substances are known, God might be known through the knowledge of them, as if from a closer vantage point, as we showed; and if it is necessary to identify ultimate felicity with some sort of knowledge of God, as we proved above; then it is not possible for man’s ultimate felicity to come in this life.

2 Again, the ultimate end of man brings to a termination man’s natural appetite, in the sense that, once the end is acquired, nothing else will be sought. For, if he is still moved onward to something else, he does not yet have the end in which he may rest. Now, this termination cannot occur in this life. For, the more a person understands, the more is the desire to understand increased in him, and this is natural to man, unless, perchance, there be someone who understands all things. But in this life this does not happen to anyone who is a mere man, nor could it happen, since we are not able to know in this life the separate substances, and they are most intelligible, as has been shown. Therefore, it is not possible for man’s ultimate felicity to be in this life.
Notes The sin comes from thinking man knows best in all. Or a man.
3 Besides, everything that is moved toward an end naturally desires to be stationed at, and at rest in, that end; consequently, a body does not move away from the place to which it is moved naturally, unless by virtue of a violent movement which runs counter to its appetite. Now, felicity is the ultimate end which man naturally desires. So, there is a natural desire of man to be established in felicity. Therefore, unless along with felicity such an unmoving stability be attained, he is not yet happy, for his natural desire is not yet at rest.
And so, when a person attains felicity he likewise attains stability and rest, and that is why this is the notion of all men concerning felicity, that it requires stability as part of its essential character. For this reason, the Philosopher says, in Ethics I [10: 1100b 5], that “we do not regard the happy man as a sort of chameleon.” Now, in this life there is no certain stability, for to any man, no matter how happy he is reputed to be, illnesses and misfortunes may possibly come, and by them he may be hindered in that operation, whatever it may be, with which felicity is identified. Therefore, it is not possible for man’s ultimate felicity to be in this life.
4 Moreover, it appears inappropriate and irrational for the time of generation of a thing to be long, while the time of its maturity is short. For it would follow that a nature would be without its end, most of the time. Consequently, we see that animals which live but a short time also take but a short time to come to perfect maturity.
Now, if felicity consists in perfect operation, in accord with perfect virtue, whether intellectual or moral, it is impossible for it to come to man until a long time has elapsed, And this is especially evident in speculative pursuits, in which man’s ultimate felicity is placed, as is clear from what we have said. For man is barely able to reach perfection in scientific speculation in the last stage of his life. But then, in most cases, only a little part of human life remains. So, it is not possible for man’s ultimate felicity to be in this life.
5 Furthermore, all men admit that felicity is a perfect good; otherwise, it could not satisfy desire. Now, a perfect good is one which lacks any admixture of evil, just as a perfectly white thing is completely unmixed with black. Of course, it is not possible for man in the present state of life to be entirely free from evils, not only from corporeal ones, such as hunger, thirst, heat and cold, and other things of this kind, but also from evils of the soul. For we can find no one who is not disturbed at times by unruly passions, who does not at times overstep the mean in which virtue lies, either by excess or defect, who also is not mistaken in certain matters, or who at least is ignorant of things which he desires to know, or who also conceives with uncertain opinion things about which he would like to be certain. Therefore, no person is happy in this life.
6 Again, man naturally shrinks from death, and is sorrowful at its prospect, not only at the instant when he feels its threat and tries to avoid it, but even when he thinks back upon it. But freedom from death is something man cannot achieve in this life. Therefore, it is not possible for man in this life to be happy.
7 Besides, ultimate felicity does not consist in an habitual state, but in an operation, since habits are for the sake of acts. But it is impossible to perform any action continuously in this life. Therefore, it is impossible for man in this life to be entirely happy.
8 Furthermore, the more a thing is desired and loved, the more does its loss bring sorrow and sadness. Now, felicity is what is most desired and loved. Therefore, its loss holds the greatest prospect of sorrow. But, if ultimate felicity were possible in this life, it is certain that it would be lost, at least by death. And it is not certain whether it would last until death, since for any man in this life there is the possibility of sickness, by which he may be completely impeded from the work of virtue: such things as mental illness and the like, by which the use of reason is halted. So, such felicity always will have sorrow naturally associated with it. Therefore, it will not be perfect felicity.
9 However, someone may say that, since felicity is a good of intellectual nature, perfect and true felicity belongs to those beings in whom a perfect intellectual nature is found, that is, to separate substances, but that in man there is found an imperfect happiness, in the manner of some sort of participation. For, in regard to the full understanding of truth, men can attain it only through enquiry, and they are utterly deficient in regard to objects which are most intelligible in their nature, as is clear from what we have said.
And so, felicity in its perfect character cannot be present in men, but they may participate somewhat in it, even in this life. And this seems to have been Aristotle’s view on felicity. Hence, in Ethics I, where he asks whether misfortunes take away happiness, having shown that felicity consists in the works of virtue which seem to be most enduring in this life, he concludes that those men for whom such perfection in this life is possible are happy as men, as if they had not attained felicity absolutely, but merely in human fashion.
10 Now, we have to show that the foregoing reply does not invalidate the arguments which we have given above.
Indeed, though man is by nature inferior to separate substances, he is nonetheless superior to irrational creatures. So, he attains his ultimate end in a more perfect way than they do. They achieve their ultimate end with such perfection because they seek nothing else, for the heavy thing comes to rest when it has occupied its own place; and even in the case of animals, when they enjoy sensual pleasures their natural desire is at rest. So, it is much more necessary for man’s natural desire to come to rest when he has reached his ultimate end. But this cannot come about in this life. Therefore, man does not attain felicity, understood as his proper end, during this life, as we have shown. Therefore, he must attain it after this life.
11 Again, it is impossible for natural desire to be unfulfilled, since “nature does nothing in vain.” Now, natural desire would be in vain if it could never be fulfilled. Therefore, man’s natural desire is capable of fulfillment, but not in this life, as we have shown. So, it must be fulfilled after this life. Therefore, man’s ultimate felicity comes after this life.
12 Besides, as long as anything is in motion toward perfection, it is not yet at the ultimate end. But all men, while learning the truth, are always disposed as beings in motion, and as tending toward perfection, because men who come later make other discoveries, over and above those found out by earlier men, as is also stated in Metaphysics II [1: 993a 31]. So, men in the process of learning the truth are not situated as if they were at the ultimate end.
Thus, since man’s ultimate felicity in this life seems mainly to consist in speculation, whereby the knowledge of the truth is sought, as Aristotle himself proves in Ethics X [7: 1177a 18], it is impossible to say that man achieves his ultimate end in this life.
13 Moreover, everything that is in potency tends to proceed into act. So, as long as it is not made wholly actual, it is not at its ultimate end. Now, our intellect is in potency in regard to all the forms of things to be known, and it is reduced to act when it knows any one of them. So, it will not be wholly in act, nor at its ultimate end, until it knows all things, at least all these material things. But man cannot achieve this through the speculative sciences, through which he knows truth in this life. Therefore, it is not possible for man’s ultimate felicity to be in this life.
14 For these and like reasons, Alexander and Averroes claimed that man’s ultimate felicity does not consist in the human knowledge which comes through the speculative sciences, but through a connection with a separate substance, which they believed to be possible for man in this life. But, since Aristotle saw that there is no other knowledge for man in this life than through the speculative sciences, he maintained that man does not achieve perfect felicity, but only a limited kind.
15 On this point there is abundant evidence of how even the brilliant minds of these men suffered from the narrowness of their viewpoint. From which narrow attitudes we shall be freed if we grant in accord with the foregoing proofs that man can reach true felicity after this life, when man’s soul is existing immortally; in which state the soul will understand in the way that separate substances understand, as we showed in Book Two  of this work.
Notes This is the point at which all new knowledge will come by revelation. No more cramming!
16 And so, man’s ultimate felicity will lie in the knowledge of God that the human mind has after this life, according to the way in which separate substances know Him. For which reason our Lord promises us “a reward in heaven” and says that the saints “shall be as the angels… who always see God in heaven,” as it is said (Matt 5:12; 22:30; 18:10).
