It's instructive for two reasons, the first because of his wonderful use of the Straw Man argument, at which poor Richard is a master; the second because it underscores once again just how bad are Robert Nozick's arguments for liberty -- as Sean Kimpton pointed out in 'The Free Radical' a few years back. When it comes to defending liberty, as Sean concludes, Robert Nozick, like many anotther supposed advocate for freedom "while advocating a libertarian political philosophy is doing more harm than good..."
[Nozick] is considered by academics to be the leading advocate for libertarianism and freedom amongst modern political philosophers, but his weak arguments are too easily trumped by self-serving intellectuals who only feel obliged to answer Nozick, rather than more substantial political thinkers like
But perhaps it is the very weakness of his arguments that add to his attraction, he is the ideal libertarian straw man - easy to knock down, and to burn while he's down.
But Nozick does have value. He shows us that if your arguments lack foundations you will undo your conclusions, no matter how true they might be.
