"Such changes can be defined as changes in structures of feeling. The term is difficult, but 'feeling' is chosen to emphasize a distinction from more formal concepts of 'world-view' or 'ideology'. It is not only that we must go beyond formally held and systematic beliefs, though of course we have to always include them. It is that we are concerned with meanings and values as they are actively lived and felt, and the relations between this and formal systematic beliefs are in practice variable (including historically variable), over a range from formal assent with private dissent to the more nuanced interaction between selected and interpreted beliefs and acted and justified experiences. An alternative definition would be structures of experience: in one sense a better and wider word, but with the difficulty that one of its senses has that past tense which is the most important obstacle to recognition of the area of social experience which is being defined. We are talking about characteristic elements of impulse, restraint and tone; specifically affective elements of consciousness and relationships: not feeling against thought, but thought as felt and feeling as thought: practical consciousness of a present kind, in a living and inter-relating continuity. We are then defining these elements as a 'structure': as a set, with specific internal relations, at once interlocking and in tension. Yet we are also defining a social experience which is still in process, often indeed not yet recognized as social but taken to be private, idiosyncratic, and even isolating, but which in analysis (though rarely otherwise) has its emergent, connecting, and dominant characteristics, indeed its specific hierarchies. These are often recognizable at a later stage, when they have been (as often happens) formalized, classified, and in many cases built into institutions and formations. By that time, the case is different: a new structure of feeling will usually already have begun to form, in the true social present."
