Berkeley's argument for the existence of God

[Pat Mustard]

Science doesn't need to be entirely empirical. Economics is mostly like geometry. You start with some axioms, and then you search for the theorems that logically follow from them. The axiomatic set of the Austrian School of Economics, for example, is called praxeology.

And the Austrian school of economics is a pile of useless bullshit as a result (albeit bullshit that most governments are happy to use).

For example its base assumption is that all actors in an economy are rational at all times and always act to maximise their own value. Anybody who has studied any scientific discipline which involves humans will tell you how wrong this assumption is (in fact one psychologist, Daniel Kahnemann has become the most original and insightful economist since Keynes simply by building a career on doing exactly that). When the single biggest underpinning of your whole system of assertions is bullshit, guess how many of the rest of them are going to be as unevidenced and unsupportable?

So your example fails, and fails hard.
