"The rather more dubious side of Nietzsche's 'evolutionism' is his glorification of the warrior -- particularly when, as an exemplification of the warrior-hero, he chooses an archetypal 'spoilt brat' like cesare Borgia. Nietzsche's own physical weakness and consequent inability to escape the atmosphere of the study leads him to take a rather unrealistic view of the man of action."
