Mark Twain was able to express in a few words the true essence of any phenomenon, characterize a person or describe a situation in such a way that it became an aphorism. All his life he studied humanity, the abyss of its vices and the pinnacle of greatness. In his works, Mark Twain laughed at him - ironically, evil, with compassion. He seemed to bring a mirror and said: look, people, you are like that, make amends.
