“This is the truth of the matter. In every human being there is a capacity, the capacity for knowledge. And every person - the most knowing and the most limited - is in his knowledge far beyond what he is in his life or what his life expresses. Yet this misrelation is of little concern to us. On the contrary, we set a high price on knowledge, and everyone strives for this knowledge more and more. "But," says the sensible person, "one must be careful about the direction one's knowing takes. If my knowing turns inward, against me, if I do not take care to prevent this, then knowing is the most intoxicating thing there is, the way to become completely intoxicated, since there then occurs an intoxicating confusion between the knowledge and the knower, so that the knower himself will resemble, will be, that which is known. If your knowing takes such a turn and you yield to it, it will soon end with your tumbling like a drunk man into actuality, plunging yourself recklessly into drunken action without giving the understanding and sagacity the time to take into proper consideration what is prudent, what is advantageous, what will pay. This is why we, the sober ones, warn you, not against knowing or against expanding your knowledge, but against letting your knowledge take an inward direction, for then it is intoxicating." This is thieves' jargon. It says that it is one's knowledge that, by taking the inward direction in this way, intoxicates, rather than that in precisely this way it makes manifest that one is intoxicated, intoxicated in one's attachment to this earthly life, the temporal, the secular, and the selfish. And this is what one fears, fears that one's knowing, turned inward, toward oneself, will expose the intoxication there, will expose that one prefers to remain in this state, will wrench one out of this state and as a result of such a step will make it impossible for one to slip back into that adored state, into intoxication. p. 118”
