One of the greatest treasures human beings have as a civilization is science. Science has allowed us to understand what the world around us is and what it is made of. Science has clarified things to us; it has given us enormous sense of understanding and control of the world we inhabit. Science has brought physical, social and moral progress. Because science is true knowledge about things, it is an objective truth.
But science is not something that simply appeared out of nowhere. Science is a body of knowledge that we have built through thousands of years of civilization.
Scientists of all times and from all regions have contributed to the progress of science through their sharp view and analysis of the observed phenomena. Each new observation, each new knowledge has enriched sciences, to the point that it became necessary to organize it in groups or categories of ideas. Those groups or categories or ideas are what we called theories.
A theory is born when the knowledge about a specific topic is deep and wide enough to be organized in a category of ideas different from the ones already established. And that is exactly what has happened to the spiritual knowledge.
Almost all scientific theories that exist hinge upon material phenomena; the type of phenomena that can be captured or sensed through the physical senses, phenomena that can be measured with devices and equipment designed to capture physical manifestations. However, none of those theories deal with the spiritual phenomenon.
Spiritual phenomena occur at a level of reality beyond the material reality; that is why the spiritual phenomena cannot be perceived by the physical senses or by devices or machines designed to record physical events. Spiritual phenomena can only be captured by mediumship, a property of the mind that allows for the beings that have it well developed to perceive, evaluate, analyze and understand the manifestations of spiritual entities.
But mediumship is not new. It was not born with Allan Kardec or with the publicly famous mediums like the sisters Margaret and Kate Fox, Eusapia Paladino, Florence Cook, Eva Carrier, Douglas Home or Aleister Crowley. It was not born with the recently famous mediums John Edwards or James van Praagh. All of which have eventually been exposed as opportunistic more related to a circus show than to a true mediumship (of course we exclude Kardec from this category; although he was not a medium, he was a pioneer in the investigation of the spiritual phenomena with less famous but more ethical mediums).
Mediumship as a tool for contacting the spiritual reality is almost as old as humanity itself. People of all cultures and regions have had it and used it to contact the afterlife. And through it a new body of knowledge about the spirit has been created.
Describing a theory about the spiritual phenomena is not an easy task. Since, unfortunately, among the many objective observations made of the spiritual reality there are intermingled fantasies, wrong interpretations and lies. Perhaps the first real serious and systematic work known in modern times begins with the books published by Allan Kardec in the mid-19th century.
That was the basic foundation for new works through schools all around the world one of which is the Basilio Scientific School Association (BSSA) where the authors of this book learned about the spiritual phenomena.
For this reason the great challenge of writing a spiritual theory is first identifying if everything written and learnt qualifies as an objective truth; and from there search convergence and coherence with what was learnt through other formal scientific disciplines like the ones studied by the authors (Biology, Physics and Anthropology); and finally, filling in the blank spaces of the theory through logical analysis of its topics so that it keeps scientific coherence.
The result has been the spiritual theory, the first scientific theory that pretends to explain the spiritual phenomenon and its relationship to the material reality. This theory allows us to see and understand the spiritual phenomenon in a wider and more global context, and subtly connected with the knowledge acquired through other sciences. The spiritual theory does not seek to confront modern sciences, it seeks to complement them.
The spiritual theory is necessary as a theoretical support to the new science known as spiritual science. The spiritual theory is necessary because any serious attempt to consider the spiritual phenomenon within a scientific field demands a theory to explain it and within which other scientists can study it and create an opinion, evaluate it or even reject it. The spiritual theory is the gateway through which we hope for the spiritual phenomenon to definitively abandon the obscurantism in which it has been kept for centuries to finally enter the clear and respectful field of modern sciences.
