Aulus Gellius, Attic Nights 6.6.1-2
ex quinque his sensibus quos animantibus natura tribuit – visu, auditu, gustu, tactu, odoratu – quas Graeci αἰσθήσεις appellant, quaedam animalium alia alio carent et aut caeca natura gignuntur aut inodora inauritave. nullum autem ullum gigni animal Aristoteles dicit, quod aut gustus sensu careat aut tactus.
Of these four senses which nature has given to animals – sight, hearing, taste, touch and smell – and which the Greeks call aistheseis, some animals lack one and others lack another, and are born naturally without sight, or without smell or hearing. But Aristotle says that no animal is ever born without either the sense of taste or touch.
