Answer
The Russian writer Fyodor Dostoevsky was a major influence on the philosophers Friedrich Nietzsche and Jean-Paul Sartre. Nietzsche was drawn to Dostoevsky's exploration of the dark side of human nature, while Sartre was inspired by his existentialist themes. Both philosophers found Dostoevsky's work to be a powerful indictment of the hypocrisy and cruelty of modern society.
