Forms

ἀναισθησίᾱ (anaisthēsíā) f (genitive ἀναισθησίᾱς); first declension[1]

Etymology

It is the abstract noun from Ancient Greek ἀναίσθητος (anaísthētos, “without feeling, insensible”).[2][3][4] Wiktionary analyses it as ἀν- (an-, “not”) with αἴσθησις (aísthēsis, “sensation, perception”) and the noun suffix -ία (-ía).[1]

Earliest recorded meaning

It first appears in the Hippocratic writings and in Plato.[5][6] In the Hippocratic Coan Prenotions it is a state of stupor or torpor,[5] and in Plato's Timaeus and Philebus it is the lack of sensation.[7][5][8]

Semantic evolution

Plato also uses the phrase “with insensibility”, that is, without the help of the senses.[7][9] The dialogue Axiochus uses it of the unconsciousness of the dead,[7][5] Aristotle of people who fall unconscious, and in the Nicomachean Ethics of insensibility to pleasure and pain.[7][5][2] Dioscorides uses it for the insensibility of a patient under surgery.[7][5]

The orators use it figuratively for obtuseness and stupidity: Isocrates and Demosthenes, who speaks of acting “out of stupidity”.[5][9][8] In Christian writers it is the lack of spiritual perception, as in Dionysius of Alexandria and John Chrysostom,[5] but the ascetic writer Evagrius Ponticus uses it in a good sense: he calls blessed the mind that in prayer has gained complete insensibility.[5]

The word lived on in medieval Greek and in dialects.[10] Modern Greek took it back as a learned word, αναισθησία (anesthisía), for medical anaesthesia and, figuratively, for callousness.[11] English anesthesia (1721) comes from it through medical Latin; its use for the prevention of pain in surgery dates from 1846.[12]
