Aesthete
Etymology
From Greek "aisthetes," one who perceives, via "aisthanesthai," to perceive. The Aesthetic movement of the late nineteenth century — Wilde, Pater — made it a badge for those who prized "art for art’s sake."
noun · /ESS-theet/
A person devoted, sometimes excessively, to beauty and refined artistic sensation.
What it names
Someone for whom sensitivity to beauty is not a hobby but the organizing principle of a life.
Example
