He urges people not to rely on the tangible alone but to incorporate the unseen idea of divine revelation to save their soul.
Aquinas continues by holding up the philosophical truths, "these truths about God which humans could have discovered (Kreeft 40) as one of the two pillars necessary to construct the foundation of salvation.
