Philistine
Etymology
The Philistines were an ancient people, the biblical enemies of the Israelites. The modern sense arose in German university slang ("Philister") for townsfolk outside academic life, and was popularized in English by Matthew Arnold in "Culture and Anarchy" (1869) to attack the materialistic, culture-scorning middle class. The word thus travelled from an ethnic name to a term of cultural insult.
noun · /FIL-uh-steen/
A person indifferent or hostile to art, culture, and intellectual life.
What it names
A pointed label for smug anti-intellectualism — dismissing culture as useless.
Example
He dismissed the entire museum as a waste of money — a real philistine.
Related idea
A philistine scorns culture from indifference; a pariah is an outcast shunned by society — one rejects refinement, the other is rejected by the group.
