This was the basic gist of the earlier response that I made... Only, ironically, I could only recount it as an anecdote.

I have to give it to my art instructor though, because his lesson on gaining personal experience has really carried over into other fields well. His comments ended, temporarily, the conversation until we had gathered the requisite skills and experience to understand both his position and what we were doing. After we finished the assignment (and consequently the semester), those of us who did the work then could understand his reasoning far better than those of the class who had not done the work.
