Interpretation is an educational activity that aims to reveal meanings about our cultural and natural resources. Through various media - including talks, guided tours, and exhibits - interpretation enhances our understanding, appreciation, and, therefore, protection of historic sites and natural wonders. Interpretation is an informational and inspirational process that occurs in our nation's parks, forests, wildlife refuges, zoos, museums, and cultural sites.
Enos Mills was an interpretive guide in what is now Rocky Mountain National Park from the late 1880s to the early 1920s. He wrote Adventures of a Nature Guide and Essays in Interpretation, which was published in 1920. Mills devised a number of principles that laid a philosophical foundation for effective interpretation. He wrote, "A nature guide [i.e., interpreter] is a naturalist who can guide others to the secrets of nature." He believed in the importance of first-hand, experiental learning. Mills observed, "He who feels the spell of the wild, the rhythmic melody of falling water, the echoes among the crags, the bird songs, the winds in the pines, and the endless beat of waves upon the shore, is in tune with the universe."
Mills presented a poetic interpretation of the facts of nature. He sough to make his topics menaingful by compiling material from "nature's storybook" in the form of its "manners and customs, its neighbors and its biography." Mills Developed his principles based upon his own professional experience as an interpreter.
The next landmark contribution to a philosophy of interpretation was Freeman Tilden's Interpreting Our Heritage, initiallty published in 1957. Tilden's six "principles of interpretation" are parallel to those principles championed by Mills. Yet it is Tilden who is far better known and who is often credited with first formulating a philosophy of interpretation.
The wisdom of Tilden's principles continues to be useful; yet, a need exists to relate his work to the present and to enage the issues of the 21st century.
Over the course of the past years, many have contributed to the body of knowledge about interpretation. For example, the 1980s saw publication of an introductory handbook designed primarily for national park interpreters titled Interpreting for Park Visitors by William Lewis. The early 1990s brought Sam Ham's practical sourebook for "people with big ideas and small budgets" titled Environmental Interpretation. Most recent is a comprehensive book designed to cross the boundaries between theory and practice - Interpretation of Cultural and Natural Resources.
Out of respect for the work of Tilden and Mills, and particularly because of the familiarity so many interpreters have with Tilden's six principles, our framework of principles beings with a re-statement of Tilden's. Note that the principles have been re-worded to better reflect their treatment in the chapters that follow. In addition to these six principles, we offer nine new principles that provide a more elaborate interpretive philosophy. Here, then, are the 15 principles, which are presented in detail in the following chapters:
