In this episode, we delve into the debate on rules and principles, the topic of law and categorisation, and the connection between equality (and analogy). Why the obsession in philosophy of law with the rules/principles debate? Is the distinction purely definitional or also substantial? How is the element of genericity – not generality - important for the debate? Does equality have something to do here? And analogy? Pedro Moniz Lopes discusses with us why the distinction between rules and principles is better understood as a strong distinction, different of the kind proposed by Robert Alexy. This strong distinction is based on the key criterion of genericity – that is, based on the specificity of the action that is being governed by the norm. We explore how categorisation might not be purely didactical or pedagogical and its role in allowing us to anticipate the way entities behave in reality, the possible parallels between principles in law and causal forces in the natural world in regards to explanation, how equality factors in the discussion regarding genericity and principles, and how analogy enters the picture.
