One principle that guided the evolution of Forth and continues to guide its application, is bluntly: Keep It Simple. A simple solution has elegance. It is the result of exacting effort to understand the real problem and is recognized by its compelling sense of rightness. I stress this point because it contradicts the conventional view that power increases with complexity. Simplicity provides confidence, reliability, compactness, and speed.

Forth provides a natural means of communication between man and the smart machines he is surrounding himself with. This requires that it share characteristics of human languages, including compactness, versatility, and extensibility. I cannot imagine a better language for writing programs, expressing algorithms, or understanding computers.
