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 mankind, the abysses of its vices and the peaks of greatness. In his works, Mark Twain laughed at him ironically, evil, with compassion. It was as if he was offering a mirror and saying, “Look, people, this is what you are, correct yourself.” No one can help you: no king, no god, no hero, no democracy. Let's do it ourselves. We invite you, dear readers, to look into this mirror. The art of thinking about time and yourself. With a guiding star named Mark Twain it will be unforgettable.
