6 ideas
Grotius ignored elaborate natural law theories, preferring a basic right of self-preservation [Grotius, by Tuck]
     Full Idea: Grotius said there was a minimum core of morality (based on self-preservation), and disregarded the elaborate accounts of principles of natural law which Aristotelians had always sought to develop.
     From: report of Hugo Grotius (On the Law of War and Peace [1625]) by Richard Tuck - Hobbes Ch.1
     A reaction: Aquinas would be the key Aristotelian here. I tend towards the Aristotelian view. If you go for the minimal view, it is not clear why there is a 'right' to self-preservation, rather than a mere desire for it.
The legal positivism of Hobbes said law is just formal or procedural [Hobbes, by Jolley]
     Full Idea: Hobbes was one of the first to propose the view known as 'legal positivism' - that the criterion for deciding whether a rule is a genuine law is entirely formal or procedural
     From: report of Thomas Hobbes (Leviathan [1651]) by Nicholas Jolley - Leibniz Ch.7
     A reaction: This was opposed to the tradition of natural law, deriving from Aquinas. It is part of a picture of values draining out of the world as science comes to dominate. The is/ought distinction is its culmination. Power replaces virtue, and Thrasymachus wins.
The existence of law is one thing, its merits and demerits another [Austin,J]
     Full Idea: The existence of law is one thing; its merit and demerit another. Whether it be or be not is one enquiry; whether it be or be not conformable to an assumed standard is a different enquiry.
     From: John Austin (Lectures on Jurisprudence [1858], p.214), quoted by Jens Zimmermann - Hermeneutics: a very short introduction 6 'Positivism'
     A reaction: It is impossible to contest this point, but the issue is whether there is nothing more to law than its written existence.
Hart replaced positivism with the democratic requirement of the people's acceptance [Hart,HLA, by Zimmermann,J]
     Full Idea: Hart replaced Austin's concept of positive law as sovereign command with a more democratic ideal. In modern law-based societies the authority of law depends on the people's acceptance of a law's enduring validity.
     From: report of H.L.A. Hart (The Concept of Law [1961]) by Jens Zimmermann - Hermeneutics: a very short introduction 6 'Hart'
     A reaction: Presumably the ancestor of this view is the social contract of Hobbes and Locke.
For positivists law is a matter of form, for naturalists it is a matter of content [Scruton]
     Full Idea: For the positivist, law is law by virtue of its form; for the naturalist, by virtue of its content.
     From: Roger Scruton (A Dictionary of Political Thought [1982], 'law')
     A reaction: Clearly a perverse and 'unnatural' social rule (backed by government and implied force) is a 'law' in some sense of the word. It is hard to see how you could gain social consensus for a law if it didn't appear in some way to be 'natural justice'.
Following some laws is not a moral matter; trivial traffic rules, for example [Wolff,J]
     Full Idea: Some laws have little grounding in morality. You may believe you have a moral obligation to stop at a red light at a deserted crossroads, but only because that is what the law tells you to do.
     From: Jonathan Wolff (An Introduction to Political Philosophy (Rev) [2006], 2 'Goal')
     A reaction: I would have thought such a law was wholly grounded in the morality of teamwork. It is the problem of rule utilitarianism, and also a problem about virtuous character. The puzzle is not the law, but the strict obedience to it.
