_I answer that,_ It is impossible for any created good to constitute
man's happiness. For happiness is the perfect good, which lulls the
appetite altogether; else it would not be the last end, if something
yet remained to be desired. Now the object of the will, i.e. of man's
appetite, is the universal good; just as the object of the intellect
is the universal true. Hence it is evident that naught can lull man's
will, save the universal good. This is to be found, not in any
creature, but in God alone; because every creature has goodness by
participation. Wherefore God alone can satisfy the will of man,
according to the words of Ps. 102:5: "Who satisfieth thy desire with
good things." Therefore God alone constitutes man's happiness.

Reply Obj. 1: The summit of man does indeed touch the base of the
angelic nature, by a kind of likeness; but man does not rest there as
in his last end, but reaches out to the universal fount itself of
good, which is the common object of happiness of all the blessed, as
being the infinite and perfect good.

Reply Obj. 2: If a whole be not the last end, but ordained to a
further end, then the last end of a part thereof is not the whole
itself, but something else. Now the universe of creatures, to which
man is compared as part to whole, is not the last end, but is
ordained to God, as to its last end. Therefore the last end of man is
not the good of the universe, but God himself.

Reply Obj. 3: Created good is not less than that good of which man is
capable, as of something intrinsic and inherent to him: but it is
less than the good of which he is capable, as of an object, and which
is infinite. And the participated good which is in an angel, and in
