Exogeneity – Economics and Nonknowledge

2009_07_07, by Tas Vicze

An economic fact is structured as follows: “consumers in the sample place a premium on liquidity β = 0.73.” This serves its task in economic models and allows economists to draw conclusions that are correct for all practical purposes. But in everyday life such a number is meaningless. The reason for this is that this number cuts across all discourse, all affect, and the social conditions that engender it, rendering these causalities exogenous to the non-conceptual statements of economics. As such, an economic fact’s epistemological scope is not sufficiently expressed by the all-too-philosophical categories of episteme (‘know-what’) and technē (‘know-how’)—though obviously these cannot help but play a significant part—but can be better characterized as a form of nonknowledge. This use of the term ‘nonknowledge’ is, however, not reducible to the Confucian dictum “To know what you know and to know what you do not know, this is knowledge”—which merely redoubles epistemology on itself in a transcendental begging of the question. To know what we don’t know would require that we know what we don’t know we don’t know, ad infinitum. The nonknowledge of economics is, as it were, the last instance of the Confucian limit statement. This nonknowledge takes place in a single number, which unifies (without being unitary) and commensurates (without commensurability) disparate orders of causality. The purpose of such a number is, borrowing a phrase from Roland Barthes (a far better political economist than Althusser ever was), to inexpress the expressible. Exogeneity is the reason why economics must necessarily be (in)expressed by numbers, not words—as well as why philosophy, mired in discourse, is unable to speak of economics.

In its disjunction from Knowledge proper, economics is non-paranoiac precisely to the extent that it is okay not to know. This has in the past led to accusations that economics is a form of religion, by analogy with the latter’s suppression of questions via dogmatism. This is not internal to economics, however, but rather takes place in its traversal (and subsequent travesty) in(to) discourse, where causality is truncated and contingency forgotten. Economics deals in facticity without fact (Heidegger), which as such remains open, ‘closable’ in the last instance only. The clause “for all practical purposes” helps to underscore its (non-)answerality, its indecisionality between practice and theory. Yet, economics tra(ns)verses into discourse precisely by supplying this ‘last instance’—by endogenizing it, as best illustrated by Milton Friedman and the money supply. Philosophy cannot handle exogeneity. Its own limit statement is that economics become a Theory of Everything.

A concept is a model. This implies that the only form of ‘concept’ in economics is an economic theory itself, in its entirety. This goes unnoticed because the first idea associated with economics in the public mind is “supply and demand”—this despite the fact that real economists never use these terms in practice. An introductory course in economics (many people’s only exposure to the discipline) teaches students to play around with such concepts as supply and demand, interest rates, and so on. Philosophy ‘of’ economics likewise proceeds by attaching to an economic ‘object’ such as ‘labour’, then trying to relate it to other concepts. But those few who take an intermediate economics course find that they are being taught the same information, but without concepts. ‘Objects’ are replaced with exogenous variables, or rates of change x/y (read: “derivative of x with respect to y”). An economic model is an elaborate tautology, in the extended Wittgensteinian sense of the term where pq is a tautology, since the concept of p is contained in the concept of q. Its conclusions arise from the syzygy (roughly, coalignment) of its variables along with its presuppositions (made for the sake of simplification). In an elaborate process of synergy, this syzygy creates a concept that may be imposed at will. Conclusions (prescriptive and descriptive) seem obvious to an economist but are not so to a layperson, and philosophy students pontificate about neoliberalism while econometrics students are incapable even of articulating what they don’t understand in class. Yet, it’s precisely this para-conceptual syzygy that constitutes all that is valuable in economics. What separates a good model from a bad one is that in the latter, a specific presupposition may be shown to do all the ‘work’ in providing the model’s conclusion.

Semantically, all of the interesting statements of economics take place within the preposition of a philosophical statement. As Laruelle writes, “The identity of the with (the One with the One, God with God), is the true ‘mystical’ content of philosophy, its ‘black box’.” The armchair philosopher is forced to engage in an amphibological attempt to render (pseudo-)exogeneity as endogenous, forced to autopositionally posit black boxes in the form of virtus dormitiva (Molière). Philosophy creates names for the Real, and by these purports to have explained it. Conversely, an economic variable is a name that does not name (Lao Tzu: 名可名,非常名), but non-conceptually gestures toward radical ( absolute) exogeneity.
