(1844 - 1900)
Friedrich Wilhelm Nietzsche was a German philosopher who understood that the world above is mirrored in the world within, which he named Astro-Psychology. His philosophical ideas about the "will to power," the "Übermensch," and eternal recurrence challenged conventional morality and religion. Works like Thus Spoke Zarathustra and Beyond Good and Evil profoundly influenced 20th-century philosophy and culture.
