Sickness And Judgement

Ὥσπερ οἱ πυρέττοντες νομίζουσι πικρὸν εἶναι τὸ μέλι, τῶν παρ' αὐτοῖς βεβλαμμένων γευστικῶν δυνάμεων, οὕτως καὶ τῆς ψυχῆς τις τὸ γευστικόν βλάπτεται. Καί φησιν ὁ προφήτης· Οὐαὶ τοῖς λέγουσι τὸ γλυκὺ πικρόν. Ἅγιος Νειλος, Βιβλιον Πρῶτον, Ἐπιστολὴ ΡϟΔ' Ἀγλαιος Ἀντεκηνσορι Source: Migne PG 79.156c

As those afflicted by a fever have their faculty of taste corrupted and judge that honey is bitter, so it is with those whose soul's power of taste has been harmed, and thus the Prophet says, 'Woe to those who say that what is bitter is sweet.' 1 Saint Nilus of Sinai, Book 1, Letter 194, To Aglaios the Antecessor 1 Isaiah 5.20
