Etymology: "Aestheses" is the plural of "aesthesis", a noun meaning the ability to perceive through the senses. The singular comes from the Greek "aisthēsis", meaning perception or sensation, which is derived from the verb "aisthanesthai", to perceive. English borrowed the term in its learned form, so the plural follows the Greek-derived pattern of "-is" becoming "-es" rather than a regular English "-s" addition. The word belongs to a family of terms built on the same Greek root that gave English "anesthesia", a word whose literal sense is "lack of sensation". The "an-" prefix negates the root, so anesthesia is in effect the absence of the very perception that "aesthesis" names. Readers who meet "anesthetic" or "aesthetic" will recognise the same stem, since "aesthetic" also descends from the Greek idea of sense perception rather than from any notion of beauty alone.
