Abstract: With Fragments de Lichtenberg, Pierre Senges offers a fragmented and casual biography of the writer Georg Lichtenberg, through successive and fanciful portraits that take place in a resolutely extravagant plot. The reader witnesses the elaboration of a counter-myth of the figure of the Great Writer, which conceals a strange user's manual for becoming Lichtenberg, in which Pierre Senges' readers are invited to rediscover, in order to question them, the principles of his own writing.
