What stands between our heritage and the inability of man to control his greed is law.
Europeans came to this country over 400 years ago, and were blessed by what they believed to be limitless resources. The land seemed fertile beyond reason or imagination, and wildlife could be harvested without concern for its diminishment. Or, so they thought.
Actually, I stole the form, and then modified it to fit my specific need. Pablo Picasso is most often credited with the form (good artists copy, great artists steal), but I can find references from T.S. Elliott (the immature poet imitates; the mature poet plagiarizes), Igor Stravinsky (lesser artists borrow; great artists steal), and William Faulkner (immature artists copy, great artists steal). I suspect that they all stole the form from someone else.
Truth is ever to be found in the simplicity, and not in the multiplicity and confusion of things – Isaac Newton
Interpretation gravitates to the complex. Maybe all human systems have a natural inclination toward convolution, like stormwater sprinting downstream. Bureaucracies certainly hint at this drift. There is refuge to be found in the minutia of complexity.
The principles of interpretation aren’t complex. The rules are limited; the doctrine is easy to grasp. The role of the interpreter is to simplify the complex, not to complicate the simple.
What is a theme? A theme to me should be the same as to you. An interpretive theme doesn’t differ from a literary theme. There is no need for a new definition of an age-old (Aristotelian) literary concept.
The theme is the main idea or underlying message of a literary work. The theme is a tool that unifies the various elements of the book or essay. A literary work can have more than one theme, although there is often a single theme that underlies the work.

If you aspire to being something more than a guide, or an usher, or a glorified bush beater, then you will need to provide a service beyond finding things. You will need to find meanings.
Every program or tour doesn’t need to have a theme. You can function as a guide for example, and themes may never cross your mind. Take bird guides. Bird guides can find, call, attract, and identify birds. As long as they can do the above, a bird guide will be successful. Birding clients demand little more than an expanded life list. This isn’t interpretation, though. This is guiding.
