What exactly is "not good enough"?

Letter 1. What is law?
Law as a conversation. This section is heavily influenced by Scott Shapiro’s ‘planning theory of law’ as set out in his book Legality (Harvard University Press, 2010), according to which law can be seen as a plan for achieving social goals. If in the text I have avoided the language of ‘plans’, that’s because we tend to see plans as final, whereas law is much more open-ended and ever-changing. The idea of law as a conversation is intended to convey that idea. Socrates’ mysterious definition in the pseudo-Platonic dialogue Minos that ‘Law wishes to be the discovery of what is’ (315a) actually fits very well with the idea of law being advanced here. If we see law as a conversation targeted at determining what sort of society we should live in, then law is animated by a desire to discover something objective – what sort of society of society we should live in. The dialogue Minos is notable for its rejection of the positivist identification of law with a set of laiddown or socially accepted rules. I referred to the dialogue as pseudo-Platonic as most Plato scholars think that the dialogue is not good enough to have come from Plato [emphasis mine]. However, Leo Strauss argues that it is by Plato, and was intended as a preface to Plato’s Laws: Strauss, ‘On the Minos’ in Pangle (ed), Roots of Political Philosophy (Cornell University Press, 1987). For some recent discussions of Minos, see V. Bradley Lewis, ‘Plato’s Minos: the political and philosophical context of the problem of natural right’ (2006) 60 Review of Metaphysics 17 and T. Lindberg, ‘The oldest law: rediscovering the Minos’ (2007) 138 Telos 43.
