Modern knowledge societies elevate education to the highest property.Those who command a surplus in knowledge skills will be able to reap competitive advantages and excel in the context of this new social reality.However,while this general analysis is now an accepted truth among observers,significant disagreement persists as to what is actually meant by knowledge and knowledge skills,let alone how much and which kind of knowledge is needed to succeed in modern societies.We address these open questions by deriving ageneral conception of what is to be understood by the term knowledge,and likewise,by the particular nature of skills the concept implies.We conceive knowledge as capacity for social action,that is as enabling abilities.This understanding holds important implications.Most central is the insight that knowledge is never immediately performative,but subject to social,political,and cultural interpretation processes—it is never autodeterministic.
