 It is not only for such social and political reasons, and considerations of practicality and custom, that common sense concepts have been supported. Also at stake here is the nature of the epistemic role accorded to conceptual analysis. Whether cast in terms of necessary and sufficient conditions, or more loosely, there is disagreement over how much analyses of mental disorder must be guided by everyday language and categories. Some analyses acknowledge more than the most immediate observations derived from the empirical and cognitive sciences, and may adhere to an account of mind and mental processing employing mentalist terms and normative presuppositions inapplicable within an exclusively physical framework (see  §4,  §5, and  §8).  In addition, some regard mental disorders as socially constructed entities, the existence and classification of which necessarily rely on societal features of the world (see  §10).
