The Invisible is a philosophical novel by Irish writer Samuel Beckett, in which the author uses his own unique style to explore themes of existence, identity and language. The main character, which got its name from here - Invisible, is in a state of absurd existence, where there is no clear structure of time, place and events. The work is full of deep philosophical content, a confusing monologue of the main character and poetic images, which leave a lot of space for the individual interpretation of the reader. "Invisible" is a frank challenge to literary conventions, which leaves a mark in the hearts and minds of its readers, forcing them to rethink their own perception of the world and themselves.
