Position in the field indicates the potential for a force exerted on the person, but a force that impinges "from the inside" as opposed to external compulsion. Motivation is accordingly considered to be the paramount example of social structure in action, as opposed to a residue of chance or freedom. ... Field theory offers social scientists a combination of analytical insight and attention to the concrete; further, the implicit definition of "explanation" that it brings is one that, unlike conventional sociological definitions, is internally consistent and in accord with everyday usage.
Field theory is well equipped to deal with one of the fundamental weaknesses of mainstream ssociological theory, namely its inability to do much with cases in which persons stand somewhat apart from the patterns of regularity upon which sociology focuses. Mainstream sociological theory, which consider the "sociolized" person to have preferences, needs, and desired that are "socially formed", generally has a difficult time explaining why people have such distantiation from "their" own values.
Not all human action or behavior takes place "in the field" in that it is judged susceptible to a field affect.
It is not necessarily clear that field can only induce such vertical differentiation, and it may be a problem that Bourdieu's analysis has tended to neglect horizontal differentiation that remains within the field. Horizontal differentiation may be said to exist when persons are not comparable, in that it makes no sense to say that one is better than the other according to some filed standard nor are the the same, yet for a number of reasons, we need to see them as being in the same field. Thus the game metaphor may introduce an artificial simplification that cuts against the second commanality among field theorists, namely their emphasis on concrete analysis.
Field theory implies a confident pursuit of what Lewin called "the full concreteness of the particular situation" while conventional approaches fear getting lost in "accidents". Concreteness, or attention to the particularities of this case, far from being assumed to lead to a "small picture" is inseparable from the field theorists emphasis on totality and synthesis.
In particular, field theory elegantly handles as fundamentally the same two social phenomena usually considered to be antithetical, namely the feeling that htere is some social force which constrains individuals externally and the feeling that we act on the basis of our motivations.
