The "Latent Reserve Energy" is provided by nature for the "Preservation of Species," and through this provision an impulsive, vehement energy can, at the final moment of a crisis, be called upon for the salvation of its kind.
A _seeming_ exception to this is due to the "Law of the Dominant" which overrides the action of "Latent Reserve Energy," and is a provision of nature for the preservation of the "Dominant," which is the most prominent quality in nature.
When the subject is properly understood, this _seeming_ exception will also become clear.
In the natural course, the study of heredity leads to the understanding of _predisposition_. In other words, if you have understood heredity, it will be easy to understand predisposition; for it means that the protoplasm or seed, from whichever organism it may proceed, must contain some of the salient characteristics of its ancestors, good and bad, dominant and recessive. Not only will it contain characteristics from father and mother, but from _all_ the direct ancestors. It is impossible to know exactly which points will manifest themselves, but a good many _bad_ points _may be_ eliminated by studying the ancestral line; and the direct diseases or bad characteristics of a parent, _must be_ eliminated by applying the Law of the Cross-Transmission of Characteristics.
For example: If the father has a certain disease or positive symptoms of that disease, by no means create a girl, as she will certainly be predisposed for that disease, and may pay the penalty, if "Regeneration" is not begun early. The same principle applies to the mother. If she is diseased, do not create a son, until "Regeneration" has been brought about.
Furthermore, it will be possible to improve the offspring by encouraging and promoting the good points, especially after studying and applying the above law, as well as my law of the "Determination of the Sex at Will."
Looking at the question from this point of view, we begin to realize the enormous significance of my discovery. This supplies the main reason for the study of the laws, for the "_Prevention of Diseases_."
Only when we know that every acquired characteristic may be transmitted to the offspring will we become conscious of the _terrible responsibility_ we assume when we reproduce offspring, and realize that we may create more pain and suffering instead of eliminating it.
