Objection 1: It seems that, besides philosophical science, we have no
need of any further knowledge. For man should not seek to know what is
above reason: "Seek not the things that are too high for thee"
(Ecclus. 3:22). But whatever is not above reason is fully treated of
in philosophical science. Therefore any other knowledge besides
philosophical science is superfluous.

Obj. 2: Further, knowledge can be concerned only with being, for
nothing can be known, save what is true; and all that is, is true. But
everything that is, is treated of in philosophical science--even God
Himself; so that there is a part of philosophy called theology, or the
divine science, as Aristotle has proved (Metaph. vi). Therefore,
besides philosophical science, there is no need of any further
knowledge.

_On the contrary,_ It is written (2 Tim. 3:16): "All Scripture inspired
of God is profitable to teach, to reprove, to correct, to instruct in
justice." Now Scripture, inspired of God, is no part of philosophical
science, which has been built up by human reason. Therefore it is
useful that besides philosophical science, there should be other
knowledge, i.e. inspired of God.

_I answer that,_ It was necessary for man's salvation that there should
be a knowledge revealed by God besides philosophical science built up
by human reason. Firstly, indeed, because man is directed to God, as
to an end that surpasses the grasp of his reason: "The eye hath not
seen, O God, besides Thee, what things Thou hast prepared for them
that wait for Thee" (Isa. 66:4). But the end must first be known by men
who are to direct their thoughts and actions to the end. Hence it was
