De Ebrietate

When, therefore, any one being smitten by the idea is influenced by the seal which gives an impression of the particular virtues, perceiving, and comprehending, and admiring the most God-like beauty of that idea which he is approaching, as having received the impression of that seal, then a forgetfulness of ignorance and folly is at once engendered in him,

On which account the scripture says, "Wine and strong drink thou shalt not drink, neither thou nor thy sons after thee," when ye enter into the tabernacle of the testimony or approach the altar of sacrifice; and he goes through all these details not more by way of prohibition than of explaining his intention. In truth, for one who was issuing prohibitions, it was appropriate to say, Drink not wine when you are performing sacrifice; but for one who is declaring his opinion, it is more suitable to say, Ye shall not drink. For it is impossible for a man to admit ignorance, which is the cause of intoxication and of ignorance of the soul, if he be one who studies the generic and specific virtues and devotes himself to the pursuit of them.

And he very often speaks of the tabernacle of testimony, in truth, inasmuch as God is the witness of virtue, to whom it is honourable and expedient to attend, or inasmuch as it is virtue which implants steadiness in our souls, eradicating ambiguous, and doubtful, and hesitating, and vacillating reasonings out of them by force, and revealing truth in life as in a court of justice.

And the scripture says that, "he shall not die who offers abstemious sacrifices;" since ignorance brings death, and education and instruction bring immortality. For as in our own bodies disease is the cause of dissolution, and health of preservation; so in the same manner in our souls also, that which saves is prudence, for this is a kind of good health of the mind; and that which destroys is folly, which inflicts an incurable disease.
