Without the Bacchic element, life would be uninteresting; with it, it is dangerous.

Bertrand Russell in History of Western Philosophy. As happens with Russell a little bit of nonsense intermingled with insight.

Civilization checks impulse not only through forethought, which is a self-administered check, but also through law, custom, and religion. This check it inherits from barbarism, but it makes it less instinctive and more systematic. Certain acts are labelled
criminal, and are punished ; certain others, though not punished by law, are labelled wicked, and expose those who are guilty of
them to social disapproval. The institution of private property brings with it the subjection of women, and usually the creation
of a slave class. On the one hand the purposes of the community are enforced upon the individual, and, on the other hand the individual, having acquired the habit of viewing his life as a whole, increasingly sacrifices his present to his future.

It is evident that this process can be carried too far, as it is, for instance, by the miser. But without going to such extremes prudence may easily involve the loss of some of the best things in life. The worshipper of Dionysus reacts against prudence. In intoxication, physical or spiritual, he recovers an intensity of feeling which prudence had destroyed; he finds the world full of delight and beauty, and his imagination is suddenly liberated from the prison of every-day preoccupations. The Bacchic ritual produced what was called "enthusiasm," which means, etymologically, having the god enter into the worshipper, who believed that he became one with the god. Much of what is greatest in human achievement involves some element of intoxication, some sweeping away of prudence by passion. Without the Bacchic element, life would be uninteresting; with it, it is dangerous. Prudence versus passion is a conflict that runs through history. It is not a conflict in which we ought to side wholly with either party.
