Thought […] is not to be found only in theoretical formulations, such as in philosophy or in scientific discourse; it can and must be analysed in all the ways of saying, of doing, of conducting oneself in which the individual manifests itself and acts as a subject of knowledge, as an ethical or juridical subject, as a subject conscious of oneself and of others. In this sense, thought is considered the form of action itself, action as implying the play of truth and falsity, the acceptance or the refusal of the rule, the relation to oneself and to others. The study of forms of experience will thus be conducted on the basis of an analysis of ‘practices,’ discursive or not, if this designates different systems of actions as inhabited by thought thus understood.
