_On the contrary,_ Other sciences are called the handmaidens of this
one: "Wisdom sent her maids to invite to the tower" (Prov. 9:3).

_I answer that,_ Since this science is partly speculative and partly
practical, it transcends all others speculative and practical. Now one
speculative science is said to be nobler than another, either by
reason of its greater certitude, or by reason of the higher worth of
its subject-matter. In both these respects this science surpasses
other speculative sciences; in point of greater certitude, because
other sciences derive their certitude from the natural light of human
reason, which can err; whereas this derives its certitude from the
light of divine knowledge, which cannot be misled: in point of the
higher worth of its subject-matter because this science treats chiefly
of those things which by their sublimity transcend human reason; while
other sciences consider only those things which are within reason's
grasp. Of the practical sciences, that one is nobler which is ordained
to a further purpose, as political science is nobler than military
science; for the good of the army is directed to the good of the
State. But the purpose of this science, in so far as it is practical,
is eternal bliss; to which as to an ultimate end the purposes of every
practical science are directed. Hence it is clear that from every
standpoint, it is nobler than other sciences.

Reply Obj. 1: It may well happen that what is in itself the
more certain may seem to us the less certain on account of the
weakness of our intelligence, "which is dazzled by the clearest
objects of nature; as the owl is dazzled by the light of the sun"
(Metaph. ii, lect. i). Hence the fact that some happen to doubt about
articles of faith is not due to the uncertain nature of the truths,
