For example, one knows what a driver of an automobile signaling intent to make a left turn is doing in the middle of an intersection because one knows the rule governing such procedures. Indeed, it is a readily demonstrable fact that a good deal of the sense we make of the things happening in our presence depends on our ability to assign them to the phenomenal sphere of influence of some rule . Not only do we do this but we count on it happening . That this is so is richly documented in the work of Goffman who has shown how persons conduct themselves in such a way as to enable observers to related performances to normative expectation . When we consider the set of highly schematic rules subsumed under the concept of rational organization, we can readily see an open realm of free play for relating an infinite variety of performances to rules as responses to these rules.
