That’s the title to co-blogger Warren Gibson’s latest piece in the Freeman. I wish I could copy and paste the whole thing, but you’ll have to settle for this juicy tidbit:

Let’s start with what methodological individualism is not.  It has nothing to do with “rugged individualism.”  It is not ideology at all.  It is a term that describes the essential nature of human thought and action.  It is a bedrock principle on which Mises grounds his entire exposition of economics.

“The Hangman, not the state, executes a criminal.”  This is Mises’s pithy summary of methodological individualism […]

When we think about the hangman from the point of view of praxeology (Mises’s name for the science of human action) we are not concerned with the social or psychological factors that may have influenced his action, nor the neural firings in his brain, nor the musculoskeletal actions in his arm.  We are simply observing that actions are always initiated and carried out by individuals and are always motivated by the individual’s expectation of being better off as a result of the chosen action rather than some alternative.
