LÁSLÓ CSONTOS<strong>and</strong> ends with<strong>in</strong> the framework <strong>of</strong> a comprehensive computationbefore we set out on our course <strong>of</strong> action’ (Lachmann 1971:34).The social sciences, accord<strong>in</strong>g to Lachmann, should follow whathe calls the praxeological method. In a brief outl<strong>in</strong>e <strong>of</strong> the scope <strong>and</strong>nature <strong>of</strong> this method, Lachmann presents the follow<strong>in</strong>gcharacterisation:Human action is not determ<strong>in</strong>ate, but neither is it arbitrary.It is bounded, firstly, by the scarcity <strong>of</strong> means at the disposal<strong>of</strong> actors. This circumstance imposes a constra<strong>in</strong>t on thefreedom <strong>of</strong> action. It is bounded, secondly, by thecircumstance that, while men are free to choose ends topursue, once they have made their choice they must adhere toit if consistent action with a chance <strong>of</strong> success is to bepossible at all. In other words, human action is free with<strong>in</strong> anarea bounded by constra<strong>in</strong>ts. Obstacles <strong>of</strong> various k<strong>in</strong>dsfurther limit the area <strong>of</strong> freedom.(Lachmann 1971:37)The praxeological method has to take these circumstances <strong>in</strong>toaccount. Causal explanation <strong>in</strong> the field <strong>of</strong> action cannot hope toatta<strong>in</strong> determ<strong>in</strong>ateness, but this does not mean that we must giveup all hope <strong>of</strong> explanation. What we may hope to accomplish hereis to be able to show to what ends, means <strong>and</strong> obstacles humanaction is oriented. Orientation thus emerges as a concept asfundamental to praxeological study as determ<strong>in</strong>ateness is tonatural science (ibid.: 37).Let me try to elucidate the logical structure <strong>of</strong> the abovearguments <strong>and</strong> the logic <strong>of</strong> teleological explanations <strong>of</strong> <strong>in</strong>dividualhuman action with the help <strong>of</strong> a simple example. 8 Suppose weobserved the conduct <strong>of</strong> a certa<strong>in</strong> <strong>in</strong>dividual, B, <strong>and</strong> we found, after<strong>in</strong>tentionalistically <strong>in</strong>terpret<strong>in</strong>g her action, that she did x, where xdenotes a particular action type or action. In other words, wesuppose that we have succeeded <strong>in</strong> giv<strong>in</strong>g an empirically soundanswer to a ‘What did B do?’ type <strong>of</strong> question, <strong>and</strong> the answer,astonish<strong>in</strong>gly enough, turned out to be: ‘B did x.’Now suppose that, as good <strong>and</strong> curious scholars, we do not stophere, but go a step further, <strong>and</strong> decide to f<strong>in</strong>d out: ‘Why did B do x?’How can we answer, or, for that matter, how do economists answerthese k<strong>in</strong>ds <strong>of</strong> ‘Why?’ questions? Of course, by construct<strong>in</strong>g idealtypes <strong>of</strong> human action <strong>and</strong> putt<strong>in</strong>g forward empiricalgeneralisations, Weber replied. Lachmann, however, f<strong>in</strong>ds this94
