It is sometimes said - because he said it himself - that Nietzsche philosophizes "with a hammer". This implies that he would not be picky, that he would not care about nuances, preferring to the crumbs and chips the pieces of wood well carved and the whole bread that holds to the body. It is true that Nietzsche is not easy to read, because poetic digressions, irony, metaphors and hyperbolic flights of fancy are mixed in with his well-ordered demonstrations. But when we say that he hits hard, with a hammer, we should understand that he hits violently, but just, in the recesses where the thought does not like to venture: if there were a hundred Pandora's jars, they would remove all the lids, not to spread all over the place the evils, but to multiply the problems, among others those that it would cost to solve. But perhaps it is quite the opposite: following its gorges and meanders, Nietzsche's thought flows clear and limpid in the bed it digs. It is therefore understandable that "interpreting Nietzsche" is a difficult task, and that he has as many interpreters as readers. What if the "mystery" of Nietzsche was only in the way he managed to make of himself a mystery?
