Considering Weber’s social scientific realism

I spent the last couple of days reading. I am making efforts to reword Weber’s methodological stance through concepts I am familiar with. Here I would love to refer to entity realism and structural/causal realism. I tried to concieve what Weber would think and say in these terms.

Entity realism: this comes from the philosophy of physics, currently applied to social sciences. At the bottom line this idea is very simple: our scientific terms refer to entities that are real. There are electrons in reality and they have the properties we attribute to them. This problematic, I know. No theoretical description is full, so when an entity realist characterize electrons, he can portray only ’a slice of reality’ at best. An entity realist is unable to seize all the features of electron, but – and this is important – he attributes features to the electron that it really has. I think Weber would be an entity realist. I found a very interesting paragraph in Ringer’s Max Weber’s methodology. Referring to Mommsen, on page 118 the author writes: ideal types cannot be constructed without regard for realities. So, and this is very essential to me, Weberian abstract-theoretical ideal types are constructed (and should be constructed) so that the researcher examines reality and seize those features of the entities that are important to him as for his research interest. As I concieve ideal types, an ideal type is constructed from real features. Rationality of the homo oeconomicus is the rationality of everyday human beings – but in reality this rationality is corrupted or disturbed by a lot of mental, psychological and social (and so forth) factors. But rationality is ’out there’, it is a part of our complex picture. Following Weber we are interested in partial truths, but the elements we exaggerate in ideal types are real features of our fellow agents.

Structural/causal realism: this also comes from the philosophy of physics. To simply put, the causal/structural connections we depict in theories are real. If I tried to conceive neoclassical economics in a Weberian fashion and according to structural/causal realism, I would say: Weber is a structural realist. In these terms, however, we have only partial truths again: treading Weber’s footsteps, we seize some causal mechanisms of the complex real causal structure – but these mechanisms are real and effective causal mechanisms. I think Weber would say: in the Marshallian cross, an increase in the price would really reduce demand. That is, the mechanism underlying this basic model of market exchange is about an effectice cause-and-effect connection – much more than an empirical regularity. When I read Whimster and Bruun’s brilliant foreword to the collected methodological writings, I found a passage that seems to support my idea: on page xxvi they trace Weber’s causal notion back to Radbruch and place Weber’s causality in the context of legal responsibility. So, I think, Weber is interested in real and objective causal connections.

As far as the realism-instrumentalism debate is considered, I believe Weber is important part of the context. Let’s have Friedman’s instrumentalism: with his parable in F53 on the leaves acting as if they were able to rationally consider their positions, Friedman gives up entity realism. He argues for assumptions that can be set up neglecting the real features of entities he ’portrays’. Thus, Friedman abandons the idea of entity realism (even as partial truths). It is questionable whether Friedman was a causal realist. Accordig to Kevin Hoover, he was, but I don’t think so (I think entity realism and causal realism is a package, causall realism cannot be achieved without entity realism). To simply put, with his emphasis on predictive performance of theories, he pays no attention to the causal connections behind macro-social phenomena. I think the whole F53 paper is devoted to the idea that researchers should be uninterested in the causal connections, and it is only predictive performance that matters. In these terms, Hausman rightly debates Friedman’s methodological stance.

To have an example: there is a widely cited anecdote in statics about a ’model’ in which the number of storks is the independent and the number of newborn babies is the dependent variable. For Friedman, such a model is a useful model as long as it provides good predictions. For Weber, such a model, I think, would be unacceptable for such a model would say nothing about the real causal connections.

Is this hairrising…?

Weber and Lucas: a different narrative?

Weber and Friedman’s story featured Knight as the most probable mediator of ideas. However, if we turn to the post-Friedmanian developments in Chicago business-cycle theories, the emergence of Weberianism seems to be implausible for Knight’s effacement at Chicago’s Department of Economics. Hence, the stage for both Knight and Weberian ideas fundamentally changed after WWII (Van Horn & Mirowski, 2009). There exists a narrative according to which modern Chicago economics as an educational and scientific conception is strongly reliant upon Knight (Reder, 1982). The present consensus, however, underplays his influence. As Emmett (2011) underlines, the modern school has been working with such an institutional structure that has little to do with Knight. In the years after WWII Knight had problems finding his position in the specialized economic theorizing (Emmett, 2010; 2013).

It is dubious whether Knight’s presence in the curriculum of modern Chicago economics is enough for us to talk about institutionalized Weberianism in these years. Emmett (2009) draws attention to the fact that chapter one of Knight’s The economic organization (Knight, 1933) is still on the reading lists of Econ 301―even in Kevin Murphy’s time. This text echoes a multitude of well-known Knightian thoughts (the limited relevance of neoclassical theory, problems around dynamic economics) some of which stem from Weber (Clarke, 1991, p. 262). With neither explicit reference to Weber nor using the term ‘ideal type’, Knight briefly mentions Weber’s methodology of ideal types (footnote 5 on p. 21 and p. 28). Therefore, the text itself is a far cry from a comprehensive introduction to Weberian tenets.

Thus, the post-Friedmanian emergence of Weberianism is highly doubtful. Accordingly, studies inquisitive about the connection between Weber and Chicago economics missed extending Weberianism beyond Friedman. Focusing on Knight’s role as a mediator is a possible cause, whilst paying attention to changes in the curricula of the Department of Economics may be another one. However, in the dissemination of Weber’s ideas in the U.S. the years after WWII were significant. An expansion of Weberianism in new directions and in new scientific centres occurred in these years (Scaff, 2011, p. 273).

In Lucas’ case, however, Friedman is a possible mediator, bearing in mind F53’s Weberian reminiscences. Further possible channels might have worked during his undergraduate studies. It must be noted that in his Nobel bio Lucas (1995) places a great emphasis on his B.A. in history. History, together with anthropology, sociology, economics, psychology and political science, belongs to social scientific education. The B.A. level education of these subjects was an assignment of the College of the University of Chicago working as an autonomous administrative unit. The College established a three-year sequence of subjects in the social sciences, paralleled with similar three-year sequences in the natural sciences and humanities. This three-year sequence in the social sciences consisted of three subjects, each with a different focus (Singer, 1948). In this subject matrix the course ‘Soc 2’ (Social Sciences 2) has the most importance as far as Weberianism is considered. Under this label students studied Weber’s Protestant ethic (Weber, 1930) as a part of the theories necessary for understanding society.

A careful reading of the Protestant ethic has been an accentuated constituent of the curriculum for decades (Levine, 1992, p. 110; Schudson, 1992, p. 137), so it was in Lucas’ time, and not only in Chicago (Mims, 1952, p. 29). The reading lists featured the 1930 English edition of the Protestant ethic, translated by Parsons, to which economic historian Richard Tawney wrote a foreword (the foreword itself was also a compulsory reading). This work of Weber is a masterpiece of the application of the methodology of ideal types. In the foreword, accordingly, Tawney underlines how significant Weber’s social scientific methodology is for economics. For him, moreover, the method of the essay is as important as its conclusions (p. I(b)).

Protestant ethic is a not a systematic introduction to Weber’s methodology. The text, however, provides an effective summary of the methodology of ideal types. In the first two pages of chapter two Weber puts forward his idea about the purpose of social scientific conceptualization. It is to highlight some individual parts of historical reality and to unite them into a consistent conceptual whole―which is the ideal type. Here Weber also underlines the requirement that we ought to properly adjust our theories to the facets of reality we are interested in, though our current point of view is by no means the only possible aspect from which we can approach a social phenomenon (Weber, 1930, pp. 47-48). In a lengthy note (p. 192) Parsons also drew attention to both the significance of these principles and Weber’s revaluation of the methodology of the social sciences.

The translation history of Weber’s works is also worth attention. In the 1950s the texts indispensable to a methodological study of the Protestant ethic were all available in English. In 1927 Knight translated Weber’s General economic history (Weber, 1927), a mature form of Weber’s comparative historical sociology. The other magnum opus was the Protestant ethic. In 1934-35 Edward Shils teamed up with Henry A. Finch in Chicago translated three methodological essays (Objectivity in social science and social policy; The meaning of ethical neutrality; Critical studies in the logic of the cultural sciences), published in a single volume in 1949 (Weber, 1949). The English edition of the complete text of Economy and society providing a detailed description of the ideal type methodology came out only in 1968 (Weber, 1968/1978), though the methodological introduction (Basic sociological terms, including the famous Methodological foundations) became available as early as in 1937-38. Thanks to Shils, the text circulated among the students and the academic staff. Even though sociologists showed a more intense interest in Weber (Scaff, 2011, pp. 201-6; Sica, 2004; Derman, 2012, pp. 39-9), Weber as we have seen was an accentuated constituent of the general social scientific education in Chicago.

It is also Lucas’ Nobel bio where he mentions Belgian historian Henri Pirenne as a major influence on him. Reading Pirenne may be an additional source of Weberianism. In methodological terms, Pirenne applied the same comparative historical method as Weber advocated. Comparative method was a cultivated approach in scientific historiography, regarded as the best way of elevating history to glorious prestige. For Pirenne, comparative method served as a reality check in order to conform social scientific generalizations. In this framework, social science lead to generalizations through a process where empirical justification of the causes is a high-ranked aspect (Lorenz, 2009, pp. 399-401). As with Friedman, however, we ought to avoid overemphasizing Lucas’ exposure to Weberianism. The attitude of Chicago academics towards Weber has always been rather ambivalent, especially after political philosopher Leo Strauss’ arrival at Chicago (1949). Strauss had a very negative judgement about Weber and due to his scholarly power he could profoundly bias convictions on Weber. This likely means that when Lucas received his history degree, he might have been rather negatively affected by Strauss’ viewpoint which was widely known in those years. Such distortions might also have contributed to Weber’s turning into an implicitly cited authority in social sciences.

Reconstructing Friedman’s exposure to Weberianism

Knight’s intellectual power and his influence on Friedman are highly difficult to characterize. Consequently, it is also difficult if not impossible to reconstruct the channels through which Friedman might have been exposed to Weberian effects. A possible channel was Knight’s formal and informal environment, for example Knight’s dinners on Sunday evenings―Friedman is reported to have been a member of this eminent intellectual circle (Emmett, 2015). One would need to engage in dubious speculations to highlight the significance of the Knight circle. However, it is Knight’s personal impact that Reder (1982, p. 6) underlines as the main channel of his influence.

From the middle of the 1930s Stigler (1985, p. 2) reports even a Weber seminar he himself attended. According to Edward Shils’ commentaries, the seminar was in 1936, built on the close reading of the original German edition of Weber’s Wirtschaft und Gesellschaft (Economy and society), a highly important text in methodological terms (Scaff, 2011, p. 209). Friedman also attended the seminar, however, Shils (1981, p. 184) reports him to have lost his interest in Weber and started to show up only sporadically. This episode makes the intellectual connection between Weber and Friedman doubtful and implausible. In this context, Hoyningen-Huene draws attention to Knight’s compilation published in 1935 (The ethics of competition), co-edited by Friedman. From this fact and the editorial Hoyningen-Huene (2017, p. 12) infers that Friedman was likely to thoroughly know Knight’s Economic theory and nationalism and hence to be exposed to some Weberian effects.

This paper of Knight is commonly regarded as his most famous methodological work (Emmett, 2006, p. 113). For Knight, applying ideal types in economics is an explicit requirement. By meeting this requisite, theory gets far from reality, though acquires universal validity where mechanical analogy is justified to apply. However, for real economic actors and economic actions differ from their theoretical counterparts, caveats about the limited applicability of the theory still hold. Even though Knight gives no explicit references to Weber, it is Weber Knight echoes when describing neoclassical theory as a framework built from ideal types. Despite all the restrictions, Knight believed theory to be instrumental in understanding real societies (Knight, 1935, pp. 277-284).

Being highly brief and complex, not only is the text difficult to analyse, but a careful reconstruction also requires us to be cognizant of both Knight’s oeuvre and Weber’s related ideas. Even though it results from Knight’s reasoning that making the theory similar to reality is a methodological fault (Emmett, 2006, p. 114; Emmett, 2015), we ought to bear in mind the fact that Knight identified real behavioural patterns in economic laws (Knight, 1924/1999, p. 29). This is the reason why Knight is implausible to have abandoned elements of reality as the building blocks of theory. However, this is unnecessary as Knight, treading Weber’s footsteps, underlined how economists can be realists by constructing unrealistic assumptions. There is no need to introduce the current debates in which Knight’s argument is still relevant (Mäki, 2009a). For Knight, through its ideal types neoclassical economics describes not real behaviour but patterns deduced under ideal-utopian conditions. This is unavoidable in order that economics, first, could focus on the forms of actions and, second, could preserve its practical relevance.

Thus, the conditions of the connection between Weber and Friedman are fraught with ambiguity. In this context it proves useful to analyse Friedman’s methodological principles. If I succeeded in highlighting some of Friedman’s tenets that can be directly or indirectly traced back to Weber, ambiguities around the exact nature of the connection would be of secondary importance. It must be noted that Eric Schliesser (2011) identifies some Weberian effects in Friedman’s theory without the intention of demonstrating Friedman’s direct Weberian erudition. Schliesser traces Friedman’s Weberian reminiscences back to Parsons, to whom there exists an explicit reference in Friedman’s personal notes to Viner’s Econ 303. Through Friedman, moreover, Schliesser extends these Weberian effects even to Stigler. Assuming a multitude of possible sources is unharmful to the idea of the (direct or indirect) connection between Weber and Friedman.

Friedman’s famous F53 is an epigrammatic and widely debated summary of his methodological doctrines. In the text Friedman uses the very Weberian term ‘ideal type’ for seven times. Of these instances, there are six clear cases, whilst in one case he mentions ideal and real entities, which bears resemblance to the rather informal fashion as Knight (1935, pp. 277-278) discusses ideal concepts or ideal behaviour. Besides the Weberian terminology the circumstance is also worth attention that Friedman characterizes the relationship between economic models and reality in a Weberian fashion―that is, his explication is in accordance with Weber’s notions. For Friedman economic models built upon ideal types ‘are designed to abstract essential features (i.e. ‘only the forces that the hypothesis asserts to be important’) of complex reality’ (p. 9) some elements and mechanisms of which are omitted from models―elements and mechanisms that can disturb the functioning of the ideal-typical core. Ideal-typical models are by no means designed for description. By contrast, hypotheses underlying significant theories ‘will be found to have “assumptions” that are widely inaccurate descriptive representations of reality, and, in general, the more significant the theory, the more unrealistic the assumptions (in this sense)’. ’A theory or its “assumptions” cannot possibly be thoroughly “realistic” in the immediate descriptive sense so often assigned, to this term’. ’Any attempt to move very far in achieving this [highly descriptive] kind of “realism” is certain to render a theory utterly useless.’ Friedman rewords Weber (1904/1949, p. 80) when explaining: ’A hypothesis is important if it “explains” much by little, that is, if it abstracts the common and crucial elements from the mass of complex and detailed circumstances surrounding the phenomena to be explained […]. To be important, therefore, a hypothesis must be descriptively false in its assumptions’. Consequently, descriptive accuracy is unnecessary for ‘a simpler theory’ to work ‘well enough’ (pp. 14-32).

Along these lines, Friedman provides an analysis of the modelling strategy of Marshallian neoclassical economics (pp. 35-7). Neoclassical economics assumes perfect competition without regarding that as a manifest characteristic of reality. If we give credit to the suggestion that models are not designed to describe reality, abstract economic theory becomes uncriticizable on such grounds. General equilibrium is only an ‘engine’ in the Weberian sense (Clarke, 1991, p. 252), constructed to analyse the world―a statement Lucas also echoed later (Snowdon & Vane, 2005, p. 281). By designing ideal types to highlight some relevant facets of reality we make it possible to analyse a chosen mechanism as an element of the complex causal structure. Here lies the most striking puzzle of this model-building strategy for we are to bring facets of reality to the fore so that our model could be adequate about the problem under scrutiny (p. 42) (Weber, 1904/1949, p. 78). Applying this strategy, we can answer the question whether a postulated causal mechanism contributes to the emergence of some social phenomena―this is exactly the reason why we carry out empirical tests. Socio-economic actuality is full of entities differing in a multitude of aspects, though we have ideal types to accentuate characteristics and mechanisms that real entities share.

Besides the Weberian parallelisms we can find some passages in F53 where Friedman echoes Knight’s critique on neoclassical economics. In such a statement, Friedman suggests as an obstacle to objective economics ‘the fact that economics deals with the interrelations of human beings, and that the investigator is himself part of the subject matter being investigated in a more intimate sense than in the physical sciences’ (p. 4). Here Friedman directly reflects Knight’s parable on a drawer drawing a picture on himself in the act of drawing, which would apply a troublesome and infinite regress (Knight, 1935, p. 280). It is also Knight whom Friedman resounds in his short discussion on the shortcomings of dynamic monetary macroeconomics. Here Friedman refers to the problems in analysing ‘the process of adaptation of the economy as a whole to changes in conditions’ (p. 42). It is exactly the line along which Knight (1935/1999, p. 154), drawing attention to the limits of the physicalist conceptual matrix, circumscribed the territory of neoclassical economics.
