The ad fontes principle also had many applications. The re-discovery of ancient manuscripts brought a more profound and accurate knowledge of ancient philosophical schools such as Epicureanism, and Neoplatonism, whose Pagan wisdom the humanists, like the Church fathers of old, tended, at least initially, to consider as deriving from divine revelation and thus adaptable to a life of Christian virtue. The line from a drama of Terence, Homo sum, humani nihil a me alienum puto (or with nil for nihil), meaning "I am a human being, I think nothing human alien to me", known since antiquity through the endorsement of Saint Augustine, gained renewed currency as epitomising the humanist attitude. The statement, in a play modeled or borrowed from a (now lost) Greek comedy by Menander, may have originated in a lighthearted vein – as a comic rationale for an old man's meddling – but it quickly became a proverb and throughout the ages was quoted with a deeper meaning, by Cicero and Saint Augustine, to name a few, and most notably by Seneca.
