The pneumatics ("spiritual", from Greek πνεῦμα, "spirit") were, in Gnosticism, the highest order of humans, the other two orders being psychics and hylics ("matter"). A pneumatic saw itself as escaping the doom of the material world via the transcendent knowledge of Sophia's Divine Spark within the soul. — Irenaeus, Adv. Haer. I. 7, 5 Such was also the use made of the latter word by Tertullian, who in his latest works, written after his Montanism had involved him in complete separation from the church, habitually uses the word Psychici to designate those from whom he had separated.
