More philosophy of engineering

Gave a quick read of Billy Vaughn Koen's Discussion of the Method: Conducting the Engineer's Approach to Problem Solving. Koen takes a philosophical look at engineering's place in the world and does a nice job of making some important distinctions regarding engineering method; however, the text's ulimate conclusion is that everything is heuristic, and this move amounts to the same kind of surrender of realism contained in much 20th and 21st century philsophy. It hardly corresponds to most engineers' understanding of the world and is thus ultimately unsatisfying. Nonetheless, Koen is one of a very few writers to take engineering serious in a philosophical way.
