"I don't believe it. Prove it to me, and I still won't believe it"
About this Quote
The intent is classic Adams: take a reasonable posture, then turn the logic dial one notch past sanity until it becomes a mirror. His comedy works because it’s structured like philosophy and delivered like sabotage. By putting “prove” and “won’t believe” in the same breath, he exposes how belief is rarely a neutral response to facts; it’s a loyalty, a mood, an identity. The line also captures the bureaucratic loop of argument-as-procedure: you can comply with every requirement and still be denied, because the verdict was decided before the trial.
Contextually, Adams wrote in an era when science, media, and politics were already colliding into a noisy marketplace of claims, and his fiction constantly mocks institutions that confuse process with meaning. The quote lands now because it sketches the emotional logic of bad-faith debate: the pleasure of being unpersuadable, the status of refusing consensus, the way “skepticism” can be cosplay for certainty. It’s funny because it’s absurd. It sticks because it’s familiar.

| Source | Evidence: No way," said Ford a while later after they had recovered from the shock of acceleration, and were climbing up out of the planet's atmosphere, "no way," he repeated, "does anyone design and build a ship like this in a year, no matter how motivated. I don't believe it. Prove it to me and I still won't believe it." (Chapter 12). This line is spoken by the character Ford Prefect in Chapter 12 of Douglas Adams' novel. The earliest publication I can verify for the quote in a primary Douglas Adams work is the first publication of the novel in 1982 (UK paperback original by Pan Books; Wikipedia lists release date as August 1982). The ISBN-10 shown for the 1982 Pan edition is 0-330-26738-8 (often written without hyphens as 0330267388). Exact page number varies by edition/printing; the quote is reliably locatable by Chapter 12 rather than a universal page reference.
