"Why argue about things you can't prove?"
About this Quote
"Why argue about things you can't prove?" lands like a courtroom objection disguised as common sense. Coming from William Ruckelshaus - a lawyer who became one of the most consequential environmental administrators in modern America - the line reads less like a plea for civility and more like a demand for evidentiary discipline. It’s the ethos of the brief: if you can’t marshal facts, you’re not persuading, you’re performing.
The subtext is a rebuke to a certain kind of public debate where “both sides” are treated as equally legitimate regardless of empirical footing. Ruckelshaus helped build the EPA in an era when government still tried to translate messy realities into enforceable standards. In that world, arguing isn’t a sport; it’s a mechanism for decision-making that affects bodies, rivers, and budgets. Proof is the gatekeeper because policy has consequences.
But the quote also carries a strategic edge. “Can’t prove” is doing a lot of work. In law and regulation, what counts as proof is often a negotiated threshold: burdens of evidence, acceptable uncertainty, what data is considered admissible. The line can be read as a defense of science-based governance - and, in less careful hands, as a way to dismiss early warnings or moral claims that don’t fit neatly into an evidentiary box.
That tension is why it sticks. It’s a compact argument for intellectual hygiene, and a reminder that “proof” is never purely neutral; it’s a standard set by institutions, and those standards determine which truths get to matter.
