Language-Games and Biology

Communication that seeks to simply commune with another is as much a part of a 'Language-Game' like builder-assistant dialogue, as is lifting weights is a use of one's wrists like the use of a saw.  Rather, Communicability is a dimension of the preconditions of any Language-Game, just as the strength and coordination of wrists is a precondition of the ability to grip a piece of wood with one hand in order to saw it with the other.  In other words, Language is fundamentally biological, which the definition of it as an element in a Language-Game tends to obscure.
