By separating biology from chemistry they later recombined and both held shared value for each other. By separating electronics from optics, new technologies and application came into being. NLP could be described as an extension of linguistics, neurology, or psychology; separations that although may in fact be ficticious in nature are in fact expedient for human learning and the development of knowledge that is practical and inpactful on our lives. These separations are based primarily on the purpose of the study of the field itself. The purpose of NLP is as discrete from linguistics as logic is to philosophy, as discrete from psychology as neurology to medicine. Although interaction of these fields yields useful results, the lack of interaction in some areas is also useful so developments in one field can aid another. The chemist, the doctor, the psychologist, the mathematician all individually better define their separate purpose and develop their skills, so when combination and interaction occur it can yield more results, be more fruitful. An ancient Greek said it quite well in the early times of western thought:

The same, but different.

Epictetus

We would like to add, it is only the difference that makes a difference, and the same which provides the vehicle for useful interaction between fields. For instance, even though two sentences of English may use similar letters, a through z, many of these sentences will differ in meaning. Without both, language and learning would be impoverished.

So now NLP, the study of the structure of subjectivity, can take its place with other fields of study, with its own methodologies, and its own purpose, drawing information from wherever it can, offering that which is uniquely its own. So the evolution of ideas, conscious and pragmatic skill can go forward.

We ask only you, the reader, to go on. Turning this page opens the doorway to new possibilities we have found worthwhile, but years ago we would not have thought possible or real. We now know they are possible, and recognize they are only the beginnings of a continuing process. The Horizon has been identified. The adventure of exploration is for those who wish the burden and joy of confronting the awesome power of the new.
