It is within the purview of each context to define its own rules and techniques for deciding how the object-oriented mechanisms and principles are to be managed. And while the manager of a large information system might wish to impose some rules based on philosophical grounds, from the perspective of enterprise architecture, there is no reason to make decisions at this level. Each context should define its own objecttivity.
Try to remember this: what you project Is what you will perceive; what you perceive With any passion, be it love or terror, May take on whims and powers of its own. Therefore a numb and grudging circumspection Will serve you best — unless you overdo it, Watching your step too narrowly, refusing To specify a world, shrinking your purview To a tight vision of your inching shoes, Which may, as soon as you come to think, be crossing An unseen gorge upon a rotten trestle.Richard Wilbur
