It's an interesting question. But I don't think we could arrive at consensus. Nevertheless, there's a good article in Standpoint magazine (HT to Arts&Letters Daily) that explores the question. (Standpoint is a monthly magazine of culture and politics. It looks interesting.)
One of the things I found most interesting was the importance the author placed on the great economist's range of interest and experience. (Add to that the fact that Alfred Nobel seemingly didn't like economists.) To that, I can only add my own curiosity about what he would say about the ongoing debate in the profession regarding the "failure to predict" the current economic downturn.
I hope you find the article of interest. I think it relates to the post of a couple days ago (and subsequent discussion in 'comments'). Perhaps the use is in making our students a bit broader in outlook, or helping them expand what they bring to the economics table. Beyond that, I'm not sure the article has many uses in the classroom. Just an interesting comment on the state of the profession.
