"Caplan’s criticism is one of the few well-reasoned critiques, but it has received a number of responses. Most of these are actually responses to a paper he wrote in the Southern Economic Journal, “The Austrian Search for Realistic Foundations”, which is very similar, so you should have no problem applying them to this particular critique. I’ll list the responses in chronological order, and I’ll include Caplan’s own rebuttals:
“Economic Science and Neoclassicism”, by Jörg Guido Hülsmann
“Austrian Theorizing: Recalling the Foundations”, and the errata, by Walter Block
“Kaldor-Hicks Efficiency and the Problem of Central Planning”, by Edward Stringham
“Probability, Common Sense, and Realism: A Reply to Hülsmann and Block”, by Bryan Caplan
“Realism: Austrian vs. Neoclassical Economics, Reply to Caplan”, by Walter Block
“Probability and the Synthetic A Priori: A Reply to Block”, by Bryan Caplan
“Rejoinder to Caplan on Bayesian Economics”, by Walter Block
Those are the direct responses, which directly quote and criticise Caplan. Caplan’s criticisms are, however, recycled from years past, so if you really want a good understanding of Austrian Economics, I suggest you also read books and papers that deal with the specific issues (e.g. indifference) brought up. You can find a reading list here." - https://forum.freecapitalists.org/t/any-rebuttals-to-critiques-of-austrian-economics/2653/10
