Aquinas asks in Question I of the First Part of the Summa Theologica, “Whether Sacred Doctrine is Nobler Than Other Sciences?”
In his first objection he notes that the other sciences (e.g., in modern terms, the hard sciences) “seem to be more certain than sacred doctrine.” This is because faith, the principle of theology, can be doubted, while the principles of the other sciences are certifiable. This type of argument is alive and well today, as scientists, and indeed much of the Western world, see empiricism and rationalism as the only way to verifiable truth. Religion has its place, but it is relegated to interiority, assisting individuals in their quest to feel good about life. This is due in part to science’s claim to an omniscient metanarrative, i.e. that empirical research and presuppositionless logic alone can lead humanity to knowledge of the truth.
Aquinas takes this view to the cleaners in his response, saying,
…this science [theology] 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, while this derives its certitude from the light certitude from the light of divine knowledge, which cannot be deceived; in point of the higher worth of its subject matter, because this science treats chiefly those things which by their sublimity transcend human reason, while other sciences consider only those things which are within reason’s grasp.
