Céline suggests that the energy and passion of youth are often lost in the pursuit of truth, leaving individuals feeling empty and devoid of vitality. He highlights the inevitability of facing uncomfortable realities, which can feel like a slow death. The mention of 'madness' points to the idea that a certain level of irrationality or escape is necessary to cope with life's harshness.
