The book explains how excluding theology from university courses causes other subjects to overstep their limits and distort truth. This argument about the need for an integrated view of all knowledge, from science to faith, is crucial for understanding why modern education often fails to produce truly wise and well-rounded individuals who can navigate complex moral questions rather than just following technical instructions. Newman shows that when we treat every discipline as an isolated tool for career success, we lose the ability to see the whole picture of human life, which leads to a fragmented understanding of reality where economics or biology might claim to answer questions about morality or the soul that they are not equipped to answer, ultimately leaving students unprepared for the deeper challenges of existence.
