ABSTRACT
Knowing products is simple, according to some. One just learns the meanings of different elements and can then translate the messages in patients' art, saying with conviction, "This (shape, color, or subject matter) means that." Of course, there are meanings in products, in formal qualities, and in content; but they are not to be found in neat formulas or simple recipes. Those generalizations which are in current usage are useful as an indication of possibilities, sometimes probabilities, but never certainties . Human beings, after all, are complex creatures, and so is their expressive behavior and the products that arise therefrom.
