Antigonus seemed rather pleased at my question. I expect his professional advice had been slighted: he wanted to lower Eucrates’s tone,—cut down his wine, and put him on a vegetable diet. ‘What, Tychiades,’ says Cleodemus, with a faint grin,’ you don’t believe these remedies are good for anything?’ ‘I should have to be pretty far gone,’ I replied, ‘before I could admit that external things, which have no communication with the internal causes of disease, are going to work by means of incantations and stuff, and effect a cure merely by being hung on. You might take the skin of the Nemean lion himself, with a dozen of field-mice tacked on, and you would do no good. Why, I have seen a live lion limping before now, hide and all complete.’ ‘Ah, you have a great deal to learn,’ cried Dinomachus; ‘you have never taken the trouble to inquire into the operation of these valuable remedies. It would not surprise me to hear you disputing the most palpable facts, such as the curing of tumours and intermittent fevers, the charming of reptiles, and so on; things that every old woman can effect in these days. And this being so, why should not the same principles be extended further?’ ‘Nail drives out nail,’ I replied; ‘you argue in a circle. How do I know that these cures are brought about by the means to which you attribute them? You have first to show inductively that it is in the course of nature for a fever or a tumour to take fright and bolt at the sound of holy names and foreign incantations; till then, your instances are no better than old wives’ tales.’ ‘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.’
