STEPHEN D.PARSONS<strong>in</strong>sufficient <strong>in</strong> elucidat<strong>in</strong>g the nature <strong>of</strong> human action.Consequently, rather than view<strong>in</strong>g Lachmann as reject<strong>in</strong>g Mises’saccount, it is quite plausible to argue that Lachmann’s account issupplementary to that <strong>of</strong> Mises. However, not surpris<strong>in</strong>gly, thisargument does require the rejection <strong>of</strong> Mises’s strict demarcationbetween economics <strong>and</strong> history.Mises <strong>and</strong> the a prioriMises <strong>and</strong> Lachmann are both strongly anti-naturalistic <strong>in</strong> theirunderst<strong>and</strong><strong>in</strong>g <strong>of</strong> economics, believ<strong>in</strong>g that there is a sharpdemarcation between the methods <strong>of</strong> economics <strong>and</strong> the naturalsciences. With Lachmann, this anti-naturalism constitutes both areason why Weber’s work ma<strong>in</strong>ta<strong>in</strong>s significance <strong>and</strong> serves todist<strong>in</strong>guish Austrian <strong>and</strong> neoclassical economics:Weber espoused the method <strong>of</strong> <strong>in</strong>terpretation (Verstehen) forthe social sciences. In economics today the prevail<strong>in</strong>g style <strong>of</strong>thought is a neoclassical formalism which is quite untouchedby Weber s methodology <strong>and</strong> <strong>in</strong>cl<strong>in</strong>ed to take it for grantedthat the methods <strong>of</strong> the natural sciences are the only scientificmethods known to man.

They are open to various<strong>in</strong>terpretations’ (Mises 1990:18).It is precisely because experiences are open to various<strong>in</strong>terpretations that economics must proceed deductively.Consequently, economics cannot appeal to experience <strong>in</strong> order tovalidate its theorems. This is because the striv<strong>in</strong>g for universallyvalid knowledge cannot be threatened by experiences open to amultiplicity <strong>of</strong> <strong>in</strong>terpretations: ‘The social sciences can never useexperience to verify their statements. Every fact <strong>and</strong> everyexperience with which they have to deal is open to various<strong>in</strong>terpretations’ (ibid.: 5).Given Mises’s explicit rejection <strong>of</strong> the relevance <strong>of</strong> the historical34
