THE JUSTIFICATION OF NORMS
What we call justification of norms is really a justification of our decisions, choices, commitments and attitudes concerning norms. Thus, justification of norms is really justification of action.
When it comes to fundamental norms, these are not to be considered as axioms from which consequences are deduced, but as accepted common places that have to be adapted to circumstances in order to serve as such elements of justification.
The techniques of justification should not to be compared to those of formal demonstration but rather to the techniques of persuasive discourse for which the theory of argumentation and the use of dialectical forms of reasoning are most suitable.
