"He who would learn to fly one day must first learn to stand and walk and run and climb and dance; one cannot fly into flying."        Friedrich Nietzsche

Controversial German philosopher Friedrich Nietzsche is best known for his book Thus Spoke Zarathustra. Born in 1844 near Leipzig, he renounced Prussian citizenship in 1869, remaining stateless the rest of his life. In his work, he argued against the concept of an omnipotent deity, believing in a "will to power," a drive toward creativity that could explain everything from natural phenomena to human behavior. He suffered from insanity, possibly syphilis-induced, for his last ten years. He died in 1900.
