Intriguing concept, but I feel it needlessly breaks language. A more narrow (and to me, less pompous) formulation would be that social groups have their own purpose, different from (though not unrelated to) the purposes of the individual members. And this collective purpose can be read best from the actions of the collective, just like the purpose of a person is best divined from their actions (actions speak louder than words).
