I didn't, but I like the libertarian take on that: the balanced vision, between constrained and unconstrained. Libertarianism is constrained in that it sets base rules that a person must respect when interacting with others namely: respect the life, integrity, freedom and property of thy neighbour. Yet it's unconstrained in that it allows freedom of action within those rules. The key difference with other constrained schemes is that libertarianism defines the rules from the bottom up, allowing freedom, whereas liberals and keynesians define the rules from the top down, precluding freedom.
