Readers are offered a book by the famous German philosopher Bruno Bauer (1809-1882), one of the most prominent representatives of the "left" Hegelianism. In this polemical work, the author sought to show that none of the Hegelians understood the truly revolutionary, atheistic spirit permeating Hegel's philosophical system. The book was written on behalf of the representative of orthodoxy, the defender of the church and religion, these pillars of the state; but its task is essentially to "shake these foundations," to show that Hegel's philosophy contains a gigantic revolutionary force. For philosophers, historians of philosophy, social scientists, all interested readers.
