It requires judging functions to supply it with purpose and humanity and it supports judging functions by turning their hopes, beliefs and decisions into reality. By its actions changes the focus of a situation from the 'aristocratic' to the 'democratic' ie. enables one to concentrate on the situation that is instead of a principle, communal agreement or prevailing idea.
Judging function:
It relates to an artificial state of things, observation of the way things could be and how they should be. It consists of agreed upon and decided information, ethics, norms, sociality, purpose, infrastructure, social bonds, honor, beliefs, plans, abstractions and hierarchies. It's what we make of the world, it's our humanity. It requires perceiving functions to anchor it into what's actually happening around it and to enable it to create something with its intentions. By its actions it turns 'democratic' into 'aristocratic' ie. it institutionalizes information and structures human activity, creates social roles and groups out of individuals that used to interact with an environment out of their own interests.
