I. Introduction Daniel B. Klein and Jason Briggeman have written a troubling paper under the title "Israel Kirzner on Coordination and Discovery" (2010). Their paper may be seen as having two distinct aspects. Most of the paper consists of a series of exceedingly sharp criticisms of two papers of mine that focused on the "coordination" concept. As we shall see, these criticisms turn out either to be based on apparent misunderstandings, or simply to reflect a conceptual framework drastically different from my own. The substance of these criticisms does not identify serious flaws in the Mises-Hayek understanding of the market process, as my work has attempted to elaborate it. But this aspect of the Klein-Briggeman paper (which I will henceforth, with no disrespect intended, call K-B) is perhaps less significant than the second aspect. Even if IK-B's criticisms were valid, it would be necessary to point out certain serious intellectual pitfalls contained in their paper. This is because their criticisms are embedded in an idiosyncratic doctrinal-history framework (relating particularly to the Austrian tradition in modern economics). It is this framework that is the paper's second aspect.
