Why do so many people love their pet dogs so much? How does a dog communicate so profoundly with its owner? How does wagging a tail create such a strong bond of affection and attachment? The answer seems to be that the dog is signaling our emotional center in a very simple yet profound and powerful way. I call this messaging system "Primal Messaging" or "Limbic Calculus" Informally, people sometimes use words such as "chemistry" or "vibes" with a similar meaning.

Definition

Signaling between the limbic systems of two beings. This signaling is often non-verbal, and often takes place below the level of consciousness.

Semantics and Syntax:

We signal messages from our limbic system to the limbic system of others using a variety of symbols, including facial expression, non-verbal emblems, voice inflection, body position, etc. Most of these messages pertain to our most basic needs. Here is the basic vocabulary of those messages:

 Note that the signal may pertain to the self (1^st person), you (2^nd person) or a 3^rd person.
