If we ever get to understand this statement of Nietzsche, we would be able to understand the FUNCTION of the Courts.
Let us look at it this way, in the USA the Supreme Court judges are known by their party affiliations, which are well known. So if the bench consists of more Democrats than Republican, their judgments , observed from the point of view of their affiliations would, engender a DEMOCRATIC bent.
If we analyze their “reasoning”, it may sound extremely logical, reasonable and fair. Are these logicality, reasonableness and fairness, which have been the bed rock of their “reasoning”, merely the hidden TOOLS in the hands of the “POWERFUL”?
MAY BE NIETZSCHE is, was and will be RIGHT ALWAYS!
