Ludwig Wittgenstein (1889-1951) is one of the most complex and controversial philosophers of the 20th century. A student of Gotlob Frege and Bertrand Russell, he stood at the origins of modern analytical philosophy. The heir to one of Europe's largest fortunes, Wittgenstein followed the ideals of non-possessiveness and lived practically in poverty. One of the most prominent minds worked as a primary school teacher, a laboratory assistant in a hospital and a gardener in a monastery. Throughout his life, he plagued himself with ethical and religious issues. In his works, Wittgenstein is a destroyer of illusions and false views, a supporter of crystal clarity of style and absolute honesty of thought. In the second half of the 20th century, Wittgenstein became a cult figure. Novels were written about him, feature films were made, and even musical works were composed. In his study, Edward Kanteryan not only sheds light on the elusive connection between the life of a philosopher, which reflected the contradictions of the turbulent 20th century, and his works, but also accessible and neatly explains the essence of his philosophical ideas from the Logical and Philosophical Treatise (1921) to Philosophical Studies "(1953), showing not a romanticized hero, but Wittgenstein - a person, intellectual and philosopher.
