. 2: The same applies to speculative science; which is
desired as the scientist's good, included in complete and perfect
good, which is the ultimate end.

Reply Obj. 3: One need not always be thinking of the last end,
whenever one desires or does something: but the virtue of the first
intention, which was in respect of the last end, remains in every
desire directed to any object whatever, even though one's thoughts be
not actually directed to the last end. Thus while walking along the
road one needs not to be thinking of the end at every step.

SEVENTH ARTICLE [I-II, Q. 1, Art. 7]

Whether All Men Have the Same Last End?

Objection 1: It would seem that all men have not the same last end.
For before all else the unchangeable good seems to be the last end of
man. But some turn away from the unchangeable good, by sinning.
Therefore all men have not the same last end.

Obj. 2: Further, man's entire life is ruled according to his last
end. If, therefore, all men had the same last end, they would not
have various pursuits in life. Which is evidently false.

Obj. 3: Further, the end is the term of action. But actions are of
individuals. Now although men agree in their specific nature, yet
they differ in things pertaining to individuals. Therefore all men
have not the same last end.

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

_I answer that,_ 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 (A. 5).
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.
