Twilight of the Idols, or, How to Philosophize with a Hammer (Götzen-Dämmerung, oder, Wie man mit dem Hammer philosophiert) is a book by Friedrich Nietzsche, written in 1888, and published in 1889. Twilight of the Idols was written in just over a week, between 26 August and 3 September 1888, while Nietzsche was on holiday in Sils Maria. Nietzsche wrote about Twilight in a letter, "This style is my philosophy in a nutshell—radical to the point of criminality...". The latter title, Götzen-Dämmerung in German, is a pun on the title of Richard Wagner's opera, Götterdämmerung, or "Twilight of the Gods". Götze is a German word for "idol" or "false god". Walter Kaufmann has suggested that in his use of the word Nietzsche might be indebted to Francis Bacon. Nietzsche criticizes German culture of the day as unsophisticated, decadent and nihilistic, and shoots some disapproving arrows at key French, British, and Italian cultural figures who represent similar tendencies. In contrast to all these alleged representatives of cultural decadence, Nietzsche applauds Caesar, Napoleon, Goethe, Thucydides and the Sophists as healthier and stronger types. The book states the transvaluation of all values as Nietzsche's final and most important project, and gives a view of antiquity wherein the Romans for once take precedence over the ancient Greeks, albeit only in the field of literature. The book is divided into twelve sections: In the foreword, Nietzsche says that the book is an escapade into the idle hours of a psychologist. He then goes on to say that this little book is a "Great Declaration of War". He says he looks forward to fix the idols with the little hammer he has. He signs it with the date of 30th September 1888. Single sentence aphorisms on a variety of topics. What does not kill me makes me stronger (German Was mich nicht umbringt, macht mich stärker) is part of aphorism number 8 from the "Maxims and Arrows" section. In full, it is: Out of life’s school of war—What does not kill me makes me stronger.
