Philosophy of Sociality [EPUB ebook] 
The Shared Point of View

Concepts based on full-blown collective intentionality (aboutness), viz., we-mode intentionality, are central for understanding and explaining the social world. The book systematically studies social groups, acting in them as a group member, collective commitment, group intentions, beliefs, and actions, especially authority-based group attitudes and actions. There are also chapters on cooperation, social institutions, cultural evolution, and group responsibility.
