As we mentioned before, at the heart of the Spiritist science is the study of the immortal spirit and our interaction with the spiritual realm.  But many of the resulting and associated philosophic teachings of the Doctrine are of a scientific nature as well, and they are often able to shed a new light on, or sometimes even add a new dimension to, the scientific knowledge acquired thus far by humans through traditional/ academic science.  In fact, many spiritualist ideas (not necessarily Spiritist, but pertaining to the survival, multiple existences, and characteristics of the soul/spirit) are starting to emerge in some areas of science that are more on the traditional side, even though they may still not be widely accepted by scientists in that field.  And in some countries, like Brazil, there are associations of Spiritists in different scientific fields, applying their knowledge of the Doctrine in their professional work.   An integration of the Spiritist philosophy and science will bring much evolution and progress to our traditional sciences in some of these areas. Below are just a few examples.

In Human Biology for example, imagine how our studies of the human body will progress when scientists take into account the existence not even just of a soul, but of the perispirit (the spirit's semi-material envelope-- see The Perispirit ) and the influence it has on every cell in the material body- through it's role as a link between the intelligent spirit and the physical body, and in it's stored records of both the spirit's actions in past lives as well as the trials or expiations that were planned for the present life.  Such recognition would also include the role or influence of the individual's energy field , created by positive or negative thoughts,  on the state of the immune system. 

In Sociology, this Doctrine of Reincarnation teaches us a great deal about the union of individuals in a family, the affinity or lack there of between certain individuals and cultures, and the evolution of our species,  all a wealth of knowledge still untapped by the great majority of today's sociologists.

Looking at Geology and Astronomy- In addition to the information in the Spirits' Book, The Genesis, from Kardec… tells us about the formation of the Earth, the Sun, the moon, and the stars, and that's just the beginning. Scientists are still looking for life on other planets, a revelation made over one hundred years ago in the Spirits' Book. Did you know that Earth is one of the least advanced planets in our solar system in terms of physical and ethical development? That Mars is even less developed, while Jupiter is considered to be greatly superior to Earth in every respect? You can find this in the Spirits' Book.

The Science of Psychology- What a difference it will make when, in analyzing our psychological state, we take into account the role of the perispirit, the natural and common occurrences of mediumistic phenomena, and the influence of past lives (not having to know the details, but merely knowing that we have lived before, and that not all our emotions or impulses are caused by events of the present incarnation). The study of mental illness will also make great strides when we consider the influence of less advanced and/or ill-intentioned discarnate spirits upon others with whom they share a past and who are presently incarnated.  In addition, the healing of suffering souls that is accomplished through this field will grow tremendously in strength when coupled with the application of spiritual healing through fluidic therapy.

How About Physics- The Great Law of Action and Reaction, Cause and Effect. Scientists have discovered this law and may of it's roles in the material world, but Spiritism- in teaching about things like reincarnation and the affinity of spirits- adds a whole new dimension to the influence of these Natural Laws. 

The above are a few examples of the scientific nature of many of Spiritism's philosophical teachings, and there are many more to be studied.
