We read Nietzsche because he is one of the all-time best questioners. In this way, he reminds us of Socrates. This is true even if, and precisely if, he questions Socrates - as well as every towering philosopher. Doing so clears the space so we can philosophize anew with a view to life.
In the first section of Beyond Good and Evil, Nietzsche exposes the "prejudices of the philosophers". As we will see, most of these prejudices relate to his observation that philosophers operate on their instinctive desire to prove what is believed in advance, as well as their willingness to assert more than they know (compare, Descartes). This sets the stage later in the book for his vision of a philosophy of the future that is more intellectually honest.
Let's read the first few aphorisms live and see what shakes out uniquely for us.
