In Science and Sanity , general semantics is presented as both a theoretical and a practical system whose adoption can reliably alter human behavior in the direction of greater sanity. In the preface to the third edition of Science and Sanity , Korzybski wrote: "We need not blind ourselves with the old dogma that 'human nature cannot be changed', for we find that it can be changed. While Korzybski considered his program to be empirically based and to strictly follow the scientific method, general semantics has been described as veering into the domain of pseudoscience.
