Appeals to authority are bad when used to defend a logical challenge to an idea. One should refute the challenge directly, not say “It must be wrong because so and so said so.”
However, when the question is, “How do the recognized experts of the Austrian community use a phrase”, then quoting from someone who is at the very heart of current AE is useful and relevant.
Put it this way. If you are going to write an article for the Quarterly Journal of AE, Mark Thornton is going to decide if you are using your words right.
A bit about Mark Thornton, from wikipedia;
"…a senior fellow and resident faculty member at the Ludwig von Mises Institute.[2] He is currently the Book Review Editor for the Quarterly Journal of Austrian Economics.[3]
…Thornton’s first book, The Economics of Prohibition, was praised by Murray Rothbard, who declared:
- *Thornton's book... arrives to fill an enormous gap, and it does so splendidly....This is an excellent work making an important contribution to scholarship as well as to the public policy debate.*
