Vincent Descombes is a famous modern French philosopher, whose works are of great interest throughout the world. His book “Addition to the Subject” is devoted to one of the most debated issues in the 20th century - what a subject is, and therefore, the definition of the essence of law, freedom, ethics, egoism, power, the phenomena of agreement, obligations and much more. Descombes considers all these questions using a broad philosophical context and extensive historical material. His credo is characterized by a post-Witt-Genstein view of the philosophical method, which involves the use of logical-semantic procedures in conceptual analysis. The book will be of interest to philosophers, legal historians, lawyers, political scientists, linguists, historians, and cultural scientists.
