The paper discussed and analyzes collective and joint intentions of various strength. Thus there are subjectively shared collective intentions and intersubjectively shared collective intentions as well as collective intentions which are objectively and intersubjectively shared. The distinction between collective and private intentions is considered from several points of view. Especially, it is emphasized that collective intentions in the full sense are in the “we-mode”, whereas private intentions are in the “I-mode”. The paper also surveys recent discussion in the literature concerning (...) the nature of collective and joint intention and defends the author's accounts against criticisms. (shrink)
