The conversation ran on to the story of the extortion, which is now again told in details. We hear further that she had tried to force open her savings-bank, and as she could not succeed in doing so, she wanted to steal the key from her mother. She expressed herself thus about the whole matter: she ridiculed her teacher because he was much kinder to the other girls than to her. But it was true that she did not do very well in his lessons, especially at arithmetic. Once she did not understand something, was afraid to ask, for fear she might lose his esteem, and consequently she made many mistakes and did really lose it. It is pretty clear that her position towards her teacher became consequently very unsatisfactory. About this time it happened that a young girl in her class was sent home because she was sick. Soon after, the same thing happened to herself. In this way, she tried to get away from the school which had become uncongenial to her. The loss of her teacher’s respect led her on the one hand to insult him and on the other into the affair with the little boy, obviously as a compensation for the lost relationship with the teacher. The explanation which was given here was a simple hint: she would be rendering a service to her teacher if she took pains to understand the lessons by sensible questions. I can add here that this hint, given in the analysis, had a good effect; from that moment the little girl became one of the best of pupils, and missed no more arithmetic lessons. We must call attention to the fact that the story of the boy’s extortion shows constraint and a lack of freedom. This phenomenon exactly follows the rule. As soon as anyone permits his libido to draw back from necessary tasks, it becomes autonomous and chooses, without regard to the protests of the subject, its own way, and pursues it obstinately. It is a general fact, that a lazy and inactive life is highly susceptible to the _coercion of the libido_, that is to say, to all kinds of terrors and involuntary obligations. The anxieties and superstitions of savages furnish us with the best illustrations; but our own history of civilization, especially the civilization and customs of the ancients, abounds with confirmations. Non-employment of the libido makes it autonomous, but we must not believe either that we are able to save ourselves permanently from the coercion of the libido by making forced efforts. To a certain limited extent we are able to set conscious tasks to our libido, but other natural tasks are chosen by the libido itself, and that is what the libido exists for. If we avoid those tasks, the most active life can become useless, for we have to deal with the whole of the conditions of our human nature. Innumerable cases of neurasthenia from overwork can be traced back to this cause, for work done amid internal conflicts creates nervous exhaustion.
