"A philosopher is, no doubt, entitled to examine even those distinctions that are to be found in the structure of all languages... in that case, such a distinction may be imputed to a vulgar error, which ought to be corrected in philosophy"
About this Quote
The intent is polemical, aimed at a powerful 18th-century habit: treating the categories encoded in words as if they were the categories of reality. If every language marks, say, subject and predicate, or speaks as if “mind” and “body” are separate kinds of things, a certain kind of metaphysician is tempted to call that nature’s blueprint. Reid calls that temptation what it is: philosophy laundering common talk into ontology.
The subtext is also anti-elitist in an interesting way. “Vulgar” doesn’t mean stupid people; it means the inherited, crowd-level assumptions smuggled in by idiom, metaphor, and convenience. Reid’s warning is that philosophers, who like to imagine themselves above the marketplace, are especially prone to being ventriloquized by it.
Context matters: Reid is a central figure of the Scottish Enlightenment “common sense” tradition, pushing back against skeptical and overly abstract systems (think Hume’s shadow, and the rationalist taste for airy distinctions). He’s not rejecting ordinary language; he’s insisting we can’t let language do our thinking for us. Philosophy’s job, in his view, is to audit the defaults.
