Unity vs. Multiplicity

Adams contrasts the unified, coherent worldview of the thirteenth century (symbolized by Chartres Cathedral and Thomas Aquinas) with the chaotic, fragmented multiplicity of the modern age, using this dichotomy as a central framework to measure historical and personal change.

The central contrast between the unity of the 13th century and the multiplicity of the 20th century, as outlined in the preface.

The chapter highlights the lack of unity among the Class of 1858 and the clash between New England and Southern types, foreshadowing the Civil War.

The chapter explores the tension between uniformitarianism (unity) and catastrophic or multiple explanations in geology, and Adams's own desire for a unifying principle like Evolution.

Central to the chapter: Adams contrasts the Church's assertion of unity with science's reduction to multiplicity (kinetic theory of gases), and questions whether unity can be affirmed or denied.
