"Grammar is the logic of speech, even as logic is the grammar of reason"
About this Quote
The second half tightens the screw. “Logic is the grammar of reason” runs the metaphor in reverse, implying that thinking itself has syntax. Reason, Trench suggests, isn’t a free-floating inner light; it’s a practiced system with constraints. The subtext is corrective, almost pastoral: if your sentences are sloppy, your thoughts may be, too. That linkage turns grammar into a kind of ethical hygiene, a way of training the mind to submit to intelligible form.
Context matters. Trench wrote in an era obsessed with classification and standardization: the Oxford English Dictionary’s early energies, the rise of formal education, the confidence that institutions could shape citizens. As an Anglican clergyman and philologist, he stood at the junction of faith, scholarship, and social order. The quote works because it smuggles a cultural claim into a neat chiasmus: mastery of language is mastery of thought, and mastery of thought is a prerequisite for moral seriousness. It’s less a neutral observation than a bid to make “correctness” feel like truth.
