na-adjective
highbrow; transcendental; aloof from worldly affairs
Describes a person, attitude, or work that is intellectually elevated and detached from practical or mundane concerns. Often carries a nuance of refined, sometimes elitist, taste.
彼の高踏的な態度は、時に周囲から誤解される。
His highbrow attitude is sometimes misunderstood by those around him.
この小説は高踏的な文体で書かれている。
This novel is written in a transcendental style.
知的 means 'intellectual' in a broad sense, whereas 高踏的 specifically implies a cultured, sometimes esoteric, elevation above everyday concerns.
Compound of 高踏 (こうとう, 'highbrow; standing above the world') and the adjectival suffix 的 (てき). 高踏 itself is a Sino-Japanese word (kango) combining 高 (high) and 踏 (step/tread), suggesting stepping above worldly matters.
