To imperfectly consider one reason for hesitating to disambiguate: a person is far more than the sum of her beliefs or rational stances. However, this is often a significant means by which we attempt to categorize one another. Be the distinctions socio-economic, familial, achievement-oriented, or religious; the reductionist constructs by which we attempt to understand one another fail to result in a comprehensive picture. That is, the sum of our thought-constructs never results in an adequate person category.
Can we get around these processes? No, nor should we despair. But, we are best served to never be satisfied with our current misunderstandings of one another. The process of disambiguation which occurs in relationships – wherein we find always that our categories spill over the edges – looks like repeatedly laying aside one misunderstanding for a better one.
