Why do historians like Christopher Bayly and William McNeill prefer focused, mid-range comparisons to grand comparative frameworks like Spengler's or Diamond's?
Think about your answer, then reveal below.
Model answer: Focused comparisons ask a specific question (e.g., why did writing develop in some civilizations and not others?) and compare only societies relevant to that question, preserving contextual detail. Grand frameworks impose a single explanatory logic on all human history, which tends to distort societies that do not conform, obscure contingency, and strip historical actors of meaningful agency.
Mid-range comparison reflects a methodological consensus in world history: generalization is possible and valuable, but it requires controlling scope. When you compare Mesopotamia and Mesoamerica on irrigation agriculture, you can hold many variables constant. When you compare all of human history at once, the variables multiply beyond analytical control, and the resulting framework tends to confirm whatever the historian assumed at the start. Focused questions produce falsifiable claims; grand theories tend toward unfalsifiable narrative.
