More of a physical point of view

To share my view of rhetorical analysis, I'd like to use an example away from writing. From what I understand, rhetorical analysis takes an experienced reader to try to pick out piece by piece what the writer is hiding or bringing attention to in the text. Therefore the reader has the responsibility of making sense or finding the underlying yet obvious point of the text or reading. So from this point of view I'd like to say that the reader must be greatly experienced and the writer or author does not necessarily need to have any training or knowlegde to be able to allow the reader to produce a sucessfull rhetorical analysis.

For example, take a Doctor. They are called upon to solve or figure out a problem that a person may have, so I'll use a Doctor as the reader. For the author ill use the example of a patient. Now, the patient knows that they have a problem and they can give you all kinds of clues and answers to what the problem is, even tell you how and where the problem is. Therefore its like the patient or the author is basically putting the structure down and underlying in writing terms, "symbolic artifacts" about what is going on. Now, it is the readers (Doctors) responsibility to figure out the problem by asking the questions and finding the answers to the underlying problem or point. A lot of the patients words and actions, or an authors performance dictates the amount one may arouse or entertain a Doctor or reader. So only based off what the patient tells the Doctor initally, the Doctor must to come up with an answer to the problem. Or in this case, compose a rhetorical analysis.
