Theory of Conservation of Emotion:
Emotion is neither created nor destroyed; it is simply converted from one form to another.
Those who have fallen in love will find it easier to understand that this so-called love develops from subtler emotions, grows into an entity, and continues being the love that it is, or transforms into either hate or indifference.
Emotional Theory of Inertia:
An emotion at rest tends to stay at rest and an emotion in motion tends to stay in motion with the same rate and in the same direction unless acted upon by an outside force.
This explains why a person coming from a recent break-up feels haunted by the last strong emotion he or she experienced. In the same way someone going through a prolonged period of pressure will tend to unconsciously long for that pressure simply becauseit has become a part of him. And she who lived a comfortable life will naturally always seek the comfortable life under unfavorable conditions, until she finally got used to the adversity around her.
Emotional Theory of Acceleration:
The acceleration or growth an emotion experiences is directly proportional to, and in the same direction as, the total effort applied to it. Obviously, the more effort there is to nurture an emotion, the faster the emotion grows.
Emotional Theory of Interaction:
For every emotional action, there is an equal and opposite emotional reaction. Thus for interest there is indifference, for like there is dislike, for fondness there is irritation, for pleasure there is pain, for courage there is fear, for delight there is abhorration, for bliss there is despair, and so on.
