The writings of the philosopher Friedrich Nietzsche speak in countless voices about innumerable questions of life. In this paper a very tentative perspective is provided on a few
phenomena related to human wisdom. After introducing Nietzsche's style, some of his comments on the function of knowledge are explored. The emphasis falls on the usefulness of
insights, on intellectual arrangement and on historical consciousness. Moving from this, Nietzsche's critical approach to morality is highlighted, with tentative answers to questions on the nature of moral judgements, the difference between good and evil, modern moralities as being anti-natural, and negative moralistic inclinations to judge, to complain, to find guilt and to lay blame. In contrast to the previous exposition of moralism, the third section deals with Nietzsche's positive approach to rationality, the scientific method and truthfulness, and stresses the overcoming of passions and guilt feelings under the influence of
increasing insight. It is argued that a genuine philosopher does not judge others indiscriminately, does not blame circumstances,
but takes his stand beyond good and evil. He is spiritually strong enough for every kind of understanding, comprehending and approving. It is pointed out that, for Nietzsche, one of the crucial questions is to see whether the human race could transform itself from a moral to wise mankind, from laying blame to saying yes to life.
