Reasonableness

The concept of reasonableness has two related meanings in law and political theory:

  1. As a legal norm, it is used "for the assessment of such matters as actions, decisions, and persons, rules and institutions, [and] also arguments and judgments."[1]
  2. As a regulative idea, it "requires... that all factors that might be relevant in answering a practical question be considered and... that they be assembled in a correct relation to each other in order to justify [a judgement]."[1]

Reasonableness should not be conflated with rationality.[1]
