But the situation is entirely symmetric. You could start with some nonE geometry.<br />Geometry in mathematics is defined formally in terms of a "space" and transformations of it. No particular form has special status.<br />Google Klein program geometry for more. <br /><br />The usefulness of E is empirical.

Well, Newtonian mechanics isn't: it is true of a limited domain, just as Euclidean geometry, And we known this empirically.<br /><br /><i>"What Kant proved is that our minds are a priori Euclidean AND non-Euclidean,"</i><br /><br />Kant "proved" no such thing.Lord Keyneshttps://www.blogger.com/profile/06556863604205200159noreply@blogger.comtag:blogger.com,1999:blog-6245381193993153721.post-89994867056872764952013-09-12T20:16:03.247-07:002013-09-12T20:16:03.247-07:00"For how do human beings know that non-Euclid..."For how do human beings know that non-Euclidean, curved Riemannian geometry is a better theory of space-time, and that Euclidean geometry is actually only a useful approximation applicable to a certain domain? The answer is: empirically, not a priori."<br /><br />Empirical experiments utilize equipment and tools that are produced on the basis of Euclidean geometry. The dimensions are Euclidean. The equipment and its relation to the researcher is assumed as Euclidean. The relationship of the equipment to the researcher to the data collection is Euclidean.<br /><br />One can't claim that using Euclidean geometry falsifies Euclidean geometry.<br /><br />The discovery of non-Euclidean geometry in cosmology does not in any way falsify the synthetic a priori truth of Euclidean geometry. Non-Euclidean geometry is BUILT on Euclidean geometry. You can't have one without the other. Both are necessary.<br /><br />What Kant proved is that our minds are a priori Euclidean AND non-Euclidean, although he did not make the non-Euclidean aspect explicit.<br /><br />Mikenoreply@blogger.comtag:blogger.com,1999:blog-6245381193993153721.post-76449086582648356862013-09-12T10:47:30.425-07:002013-09-12T10:47:30.425-07:00Ugh... Hoppe.
Has anyone noticed the degradation ...Ugh... Hoppe.<br /><br />Has anyone noticed the degradation in quality of the Austrian school since Hayek died? I'll give each an awfulness rating between 1 and 5 stars -- 1 being least awful and 5 being most awful.<br /><br />Old populariser: Henry Hazlitt (3)<br />New populariser: Peter Schiff (5)<br /><br />Old philosopher: Ludwig Von Mises (3)<br />New philosopher: Hans-Hermann (5)<br /><br />I could go on, but you get the idea. Not surprising that a school with low quality initial intellectual capital would be subject to such a rapid depreciation, but boy was it fast.

That's amazing. It's like the negation of an appeal to anonymous authority — an appeal to personal incredulity inspired by the assumed ineptitude of an unnamed, homogeneous mass of experts.

Thanks for the effort, LK, and I am looking forward to more contributions.<br /><br />Personally, I am just too impatient to systematically critique Hoppe; I quickly get to the point where I feel offended by his irresponsible use of words. After all, from someone who purports to communicate with me, I expect a demonstrable effort at intelligibility.<br /><br />Am I wrong?
