Friedrich Nietzsche 
Thus Spake Zarathustra [EPUB ebook] 

Thus Spake Zarathustra, is a work of philosophical fiction written by German philosopher Friedrich Nietzsche between 1883 and 1885. Scholars have argued that "the worst possible way to understand Zarathustra is as a teacher of doctrines". Nonetheless Thus Spake Zarathustra "has contributed most to the public perception of Nietzsche as philosopher – namely, as the teacher of the 'doctrines' of the will to power, the overman and the eternal return".
