I know there has been articles and books relating Mises to Aristotle and Max Weber -and showing how it is indeed science.
Are there any articles relating Mises to Freud or maybe even Goethe?

It's easy to refute an argument if you first misrepresent it. William Keizer
As for Freud, the usual line is that Freud is about why people choose goal X, and Mises is about what they do to achieve goal X. First chapter of human Action has a bit about it.
I was mostly thining about them due to "heterodox" methodology. Freud I only know the basics, but no in depth knowledge of how he was really working. Outside of cog psych and behaviorism - other forms of psychology aren't covered much in undergrad psych. But they are covered, considered science, and taken seriously - that is kind of what I am concerned with. Freud would be the most interesting due to a) fame b) location c) time when compared to Menger or Mises....the other "big" name, Jung seems a bit less appealing.
It looks like psychology though has made more inroads as to what science can mean when compared to economics, I would think this could be of interest to Austrians.
As for Goethe, don't know much about his methodology, other than it is heterodox.

Daniel James Sanchez has also touched on this area...you might check out his blog and article archive, but perhaps these in particular:
