“Does not an ingenuous contact with Kantian thinking, with philosophical thinking in general, contain the risk of exposing a young consciousness to a violent and sudden aging? What of a youthful will to know is preserved in a philosophy that makes one dizzy with its bony spiraling turns of the screw?”

Context: To be disciplined does not mean being silent, abstaining, or doing only what one thinks one may undertake without risk; it is not the art of eluding responsibility; it means acting in compliance with orders received, and therefore finding in one's own mind, by effort and reflection, the possibility to carry out such orders. It also means finding in one's own will the energy to face the risks involved in execution.
