We and Play

In some cases, a We aims at the generation of a concrete extrinsic product, e. g. a building crew, while in others, the purpose is an activity, e. g. an orchestra performing a symphony.  And, sometimes, a We is not a means, but what can be classified as either, with equal justification, 'purposeless', or an 'end-in-itself', e. g. a party, to which a product or an activity serves as to occasion.  Such examples illuminate We as essentially Play, i. e. the substratum of even a serious purposeful We is its playfulness.
