A social group can, indeed must, already exercise 'leadership' before winning governmental power (this is indeed one of the principal conditions for the winning of such power); it subsequently becomes dominant when it exercises power, but even if it holds it firmly in its grasp, it must continue to 'lead' as well.
Antonio GramsciFrom the moment when a subordinate class becomes really independent and dominant, calling into being a new type of State, the need arises concretely, of building a new intellectual and moral order, i.e. a new type of society, and hence the need to elaborate the most universal concepts, the most refined and decisive ideological weapons.
Antonio GramsciThe starting-point of critical elaboration is the consciousness of what one really is, and is 'knowing thyself'as a product of the historical processes to date, which has deposited in you an infinity of traces, without leaving an inventory.
Antonio GramsciCommon sense is not something rigid and stationary, but is in continuous transformation, becoming enriched with scientific notions and philosophical opinions that have entered into common circulation. 'Common sense' is the folklore of philosophy and always stands midway between folklore proper (folklore as it is normally understood) and the philosophy, science, and economics of the scientists. Common sense creates the folklore of the future, a relatively rigidified phase of popular knowledge in a given time and place.
