Welshon (philosophy, U. of Colorado-Colorado Springs) introduces the controversial 19th-century German philosopher, arguing that his bad reputation, even where deserved, should not be a reason to avoid reading him. He lays out what he thinks is the philosophical core of Nietzsche's thought on such matters as morality, nihilism, truth, psychology, and the will to power.
