A few years ago I printed out this article to read! Today I began reading it. Wonderful.
Art as action or art as object? the embodiment of knowledge in practice as research
Dr Anna Pakes, Roehampton University of Surrey, England
If I can make a short summary: Through action we know stuff.
This is right on the topic of my science & Psychodrama paper, and goes back again to Aristotle: Phronesis (see earlier post of mine) I have highlighted a bit in the quote below that may as well describe a Psychodrama session. She relates the knowing to dance, but and I am sure it applies equally if not more so to Psychodrama which is a conscious form of experimentation in addition to all that she describes.
