"What is truth?" Pontius Pilate asked Jesus, and philosophers have been wrestling with the question ever since. A fascinating new study highlighted by Reason magazine reveals that even ordinary people are deeply divided on the issue. When presented with a simple scenario (Maria sincerely tells Peter that Tom is at a party, but he isn't), only a bare majority judged her statement false based on correspondence with reality. Nearly half leaned toward coherence (it fit her beliefs at the time) or authenticity (she was sincere).

This divide isn't new. It reflects the ancient philosophical battle between two major theories of truth: correspondence (realist) and coherence (idealist).

Correspondence Theory: Truth as Matching Reality

The commonsense, realist view, dominant in everyday life and science, holds that a statement is true if and only if it corresponds to the way the world actually is. Maria's claim is false because Tom wasn't at the party, full stop. Facts are mind-independent; truth is discovered, not invented.

This view feels intuitive. It underpins empirical science, courts of law, and daily navigation of reality. But it has persistent difficulties. How exactly does a linguistic proposition "correspond" to a non-linguistic fact? What counts as a fact? Critics like the late Hilary Putnam (1926-2016), and others have argued that we never access "raw" reality unmediated by our concepts, language, or theories, making pure correspondence slippery.

Coherence Theory: Truth as Internal Consistency

Brand Blanshard (1892-1987), a leading 20th-century defender of coherence, argued that truth consists in the coherence of a belief with a comprehensive, consistent system of other beliefs. Isolated propositions don't stand alone; they're true insofar as they fit harmoniously into the whole web of knowledge, a point made by the late W. V. O. Quine (1908-2000):

This view shines in mathematics, logic, theoretical physics, and interpreting complex systems. It explains why we often accept new information because it "makes sense" with what we already know. But it has serious problems too. A fully coherent belief system could still be completely detached from reality (think of a perfectly consistent conspiracy theory or ideological echo chamber). Multiple coherent but contradictory systems are possible. Blanshard himself wrestled with these issues, pushing toward an idealist "absolute" coherence, but the theory struggles to ground itself in the external world.

Both Views Have Deep Flaws — As Philosophers Have Shown

Philosophers from Blanshard to Putnam have exposed the weaknesses in each:

Correspondence risks naive realism and the "myth of the given." We can never step outside our perceptions to verify perfect mirroring of reality.

Coherence risks relativism or solipsism — your coherent worldview might clash with mine, and neither touches objective truth, if it exists.

Putnam famously evolved from strong realism toward internal realism and pragmatic elements, showing how hard it is to separate truth from justified belief. No theory seems fully satisfactory on its own. Pragmatic theories (truth as what works) and deflationary approaches (truth as a useful linguistic device) try to split the difference but often feel like evasions.

Why This Matters in 2026

The Reason study shows this isn't abstract philosophy; it's how people actually argue about climate change, politics, gender, immigration, economics, history, and culture. One side demands correspondence to data and observable reality. The other prioritises coherence within their moral or ideological framework, or authenticity of intent. No wonder dialogue breaks down.

We live in an era of fractured epistemologies. Social media, partisan media, and ideological silos amplify coherence-based thinking ("it fits the narrative"). Meanwhile, scientific and empirical pushback insists on correspondence ("but the facts say otherwise").

Pilate's Question Remains Open

Neither theory has delivered a knock-out victory. Correspondence feels truer to our experience of a stubborn external world, yet coherence captures how we actually build and test knowledge. The best approach may be humble pluralism: lean heavily on correspondence for empirical claims while recognising coherence's role in complex reasoning, all while staying vigilant against self-deception.

Truth-seeking requires intellectual honesty, openness to evidence, and a willingness to let reality judge our beliefs rather than the other way around. In the end, Pilate's question endures because perfect certainty about truth may be beyond finite minds. For the Christian, that is not the end point, but a deliverance to faith, as philosophers/theologians such as Blaise Pascal (1623-1662) urged.
