If a historical sensibility is the temperament, then thinking historically is the practice. It is the active deployment of that sensibility as a set of tools to assess the world and make more informed choices. It is a distinct epistemology, one that offers a powerful method for evaluating causality and agency, weighing competing narratives and navigating the dilemmas of decision-making without succumbing to what can be called “paralysis by analysis.” It offers not a crystal ball, but a more sophisticated lens — a historian’s microscope — through which to see the present.
Thinking historically begins by questioning vertical and horizontal time. The vertical axis asks: How did we get here? It is the rigorous construction of a chronology, not as a mere list of dates, but as a map of cause and effect. Where this timeline begins — with the Bolshevik Revolution of 1917, the end of World War II in 1945 or the rise of China in 1979 — fundamentally changes the story and its meaning. It reveals our own unspoken assumptions about what truly drives events.
The horizontal axis asks: What else is happening? It recognizes that history is not a single storyline but a thick tapestry of interwoven threads. The decision to escalate the war in Vietnam, for example, cannot be fully understood without examining the parallel, and seemingly contradictory, efforts by the same administration to cooperate with the Soviet Union on nuclear nonproliferation. Thinking historically is the act of integrating these divergent streams.
Crucially, this practice leads us to confront our own biases, particularly outcome bias. Because we know how the story ended — how the Cold War concluded or how the 2008 financial crisis resolved — we are tempted to construct a neat narrative of inevitability. Thinking historically resists this temptation. It demands that we try to see the world as the actors of the past saw it: through a foggy windshield, not a rearview mirror, facing a future of radical uncertainty. It restores a sense of contingency to the past, reminding us that choices mattered and that the world could have turned out differently.
Ultimately, thinking historically is about asking better, more probing questions. It is a disciplined curiosity that fosters an appreciation for the complex interplay of individual agency, structural forces and pure chance. Instead of offering easy answers, it provides the intellectual equipment to engage with hard questions, a skill indispensable for navigating a future that will surely be as unpredictable as the past.
