It Is a Non-Sequitur to Conclude That Socialism’s Central Problem Is a Lack of Knowledge

Clearly, Hayek's thesis regarding the central problem of socialism is nonsensical. What categorically distinguishes socialism from firms and families is not the existence of centralized knowledge or the lack of the use of decentralized knowledge, but rather the absence of private property, and hence, of prices. In fact, in occasional references to Mises and his original calculation argument, Hayek at times appears to realize this, too. But his attempt to integrate his very own thesis with Mises's and thereby provide a new and higher theoretical synthesis fails.

The Hayekian synthesis consists of the following propositional conjunction: “Fundamentally, in a system in which the knowledge of the relevant facts is dispersed among many people, prices can act to coordinate the separate actions of different people” and “the price system” can serve as “a mechanism for communicating information.” While the second part of this proposition strikes one as vaguely Misesian, it is anything but clear how it is logically related to the first, except through Hayek's elusive association of “prices” with “information” and “knowledge.” However, this association is more of a semantic trick than rigorous argumentation. On one hand, it is harmless to speak of prices as conveying information. They inform about past exchange ratios, but it is a non-sequitur to conclude that socialism's central problem is a lack of knowledge. This would only follow if prices actually were information. However, this is not the case. Prices convey knowledge, but they are the exchange ratios of various goods, which result from the voluntary interactions of distinct individuals based on the institution of private property. Without the institution of private property, the information conveyed by prices simply does not exist. Private property is the necessary condition of the knowledge communicated through prices. Yet then it is only correct to conclude, as Mises does, that it is the absence of the institution of private property which constitutes socialism's problem. To claim that the problem is a lack of knowledge, as Hayek does, is to confuse cause and effect, or premise and consequence.
