Justice & Law Quote by Edward Coke

"Reason is the life of the law; nay, the common law itself is nothing else but reason - the law which is perfection of reason"

About this Quote

Coke is trying to do something more audacious than praise rationality: he’s attempting to seize the moral high ground for a legal system that, in practice, often looked like a tangle of precedent, privilege, and procedural gamesmanship. By insisting that “reason is the life of the law,” he turns common law from an inherited set of habits into a claim about legitimacy. If law equals “perfection of reason,” then judges are not merely referees of custom; they are custodians of an ideal. That’s a power move.

The subtext is defensive and strategic. Coke is writing in an England where the monarchy’s “reason of state” could be invoked to bulldoze ordinary courts. Declaring the common law to be reason itself is a way to deny that the king (or any executive authority) has a superior, freer form of rationality. It’s also a way to sanctify precedent: old decisions aren’t old because they’re old; they’re old because they embody accumulated reasoning. Tradition gets rebranded as logic.

The line also flatters the legal profession’s self-image. If common law is “perfection,” then lawyers and judges become technicians of the highest human faculty, not brokers for the powerful. Of course, the irony is that “reason” here isn’t a neutral, universal calculator; it’s the kind of reason that grows inside institutions, trained by elite education, and enforced through property and hierarchy. Coke’s brilliance is that he doesn’t hide the politics of that claim - he refines it into rhetoric so clean it can pass as inevitability.
