The concept of action is one of the key concepts of practical philosophy. This work examines the core of Hegel‹s concept of action, §§ 105-125 of the ‹Grundlinien‹ (Elements of the Philosophy of Right) and their references to the ‹Wissenschaft der Logik‹ (Science of Logic). The author describes and interprets the systematic content of Hegel‹s concept of action against the backdrop of the current speech act theory. The continuing relevance of the book is shown in its current translations, for example into Italian, Japanese, Spanish and Hungarian.
