Lucian Philopseudes sive incredulus 10

[10] “It seems to me,” said Deinomachus, “that when you talk like that you do not believe in the gods, either, since you do not think that cures can be effected through holy names.’ “Don’t say that, my dear sir!” I replied. “Even though the gods exist, there is nothing to prevent that sort of thing from being false just the same. For my part, I revere the gods and I see their cures and all the good that they do by restoring the sick to health with drugs and doctoring. In fact, Asclepius himself and his sons ministered to the sick by laying on healing drugs, not by fastening on lions’ skins and weasels.” ¹

[10] ‘In other words, you do not believe in the existence of the Gods, since you maintain that cures cannot be wrought by the use of holy names?’ ‘Nay, say not so, my dear Dinomachus,’ I answered; ‘the Gods may exist, and these things may yet be lies. I respect the Gods: I see the cures performed by them, I see their beneficence at work in restoring the sick through the medium of the medical faculty and their drugs. Asclepius, and his sons after him, compounded soothing medicines and healed the sick,—without the lion’s-skin-and-field-mouse process.’
