The Sources, Criteria & Procedure for Additions to the Synthesis Repertory
Parts 1 | 2 | 3
by Dr. Frederik Schroyens
When I started practicing homeopathy (1978), there was an important group of homeopaths that believed no additions should be made to Kent's Repertory.
The idea was that the Repertory contained wisely selected information and that any additions would only increase the bias of too much information. One could be tempted to believe that this was Kent's vision as well, as he introduced the third edition of his Repertory as follows: "You will find all remedies of any value contained herein. The book is complete."
However, a conversation has been reported, shortly before Kent's death, where he contradicted his wife who was making the same statement. He confessed to Dr. Frederika Gladwin that "his job was almost done. If it had to continue, his students had to take care of it."
Today there seems to be little doubt as to the necessity of additions. Yet another problem is emerging: an increasing number of homeopaths are questioning the reliability of those colleagues who suddenly report hundreds if not thousands of additions based on their clinical experience.
I believe we should take a resolute stand and treat each other's "fever for additions". Moreover, we should balance it with "fastidiousness about correct additions".
I. THE SOURCES
1. Current Additions
From which sources have additions previously been made? You will find the additions from the Repertories that are primarily used today: Boger's version of the Boenninghausen Repertory, Oscar Boericke's Repertory, Phatak's Repertory, etc.
Information from different Materia Medica books has been integrated, especially from classical authors such as:
- Hahnemann: surprisingly, many of Hahnemann's symptoms seem not to have been integrated into Kent's Repertory
- Kent's Materia Medica (fully integrated on the basis of Dr. Linda Johnston's tremendous work (Los Angeles, USA)
- Hering's Encyclopedia (this source was preferred over copying from the secondary source, Knerr's Repertory, which contains the same material)
- Allen's Encyclopedia (the original book, not the index, which contains many mistakes and omissions as we found with key-word searches using RADAR.) Whenever possible we have indicated if the information came from Allen's full text or from the Index to his Encyclopedia)
- Roberts "Sensations as if". Although some consider it a Repertory, it is a full text structured line by line. It takes much time to transcribe it to a correct repertory structure, but the book is being integrated into Kent's Repertory.
- Other Materia Medicas have been integrated, although most of them only partially, due to the amount of work involved. Worth mentioning: Clarke's Dictionary, William Boericke's Materia Medica, Phatak's Materia Medica, Borland's books, Tyler's Drug Pictures, etc.
Special thanks: to the European homeopaths collaborating under the coordination of Thomas Lowes (Munich, Germany) and to the American homeopaths collaborating with Dean Crothers (Seattle, USA). Many other homeopaths have done a great job with particular remedies taken from different sources, or with research according to their interest. In Synthesis 5, for example, you will find more complete pictures of the nosodes: additions from Henry Allen's Nosodes, reviews of Carcinosinum, Psorinum, different strains of Tuberculinum and Medorrhinum.
An important number of clinical observations from different "living" authorities have been added. The largest number of additions in this category is derived from George Vithoulkas, who was so kind as to write the foreword for this Repertory. We have taken great care to make sure that Synthesis is the best reflection of his clinical experience, which is probably the largest in homeopathy to date. George Vithoulkas has gathered a great number of homeopaths in a Clinical Centre in Athens. All consultations are supervised by experienced homeopaths or by him.
For the first time, George Vithoulkas has been written down his additions for the MIND chapter, and these are now integrated into Synthesis. The MIND chapter has now more than 1600 of his personal additions. Other authors have confirmed many of these additions. On his instruction, additions to other chapters have been added in successive versions of Synthesis.
In this version, we have included his indications on changes of degrees (most often to a higher degree). When a remedy has a higher (lower) degree according to Vithoulkas, it is followed by a sign: "merc.3vh". This means that for this rubric, "merc." should be in the third degree instead of the second degree. There are more than 1,000 such instances and one is free to follow this advice or not.
2. Future Additions
It is misleading to call any Repertory complete. More work will always be needed to further improve the quality and increase the content of Synthesis. It is certain that this job will never be completely finished. As a consequence, all current collaborators and, in fact, anyone is invited to go on with this collaboration. The most productive contributions are made when everyone does what interests him or her: the remedy he needs, the author she likes, etc.
Nevertheless a few suggestions:
- If you plan to undertake a big job, check to see that the work has not been done or started already by someone else.
- It is beneficial to recheck encoded additions, as we have done for some earlier additions.
- The priority set by most of our collaborators is to encode all information of the so-called classical authors (Hahnemann, Kent, Allen, Hering, Clarke and Boericke).
- We should continue to give priority to the most reliable information. Written sources and confirmation of existing material will remain the best choice for a long time. It is more valuable to have a confirmation by someone not belonging to the same school as the one whose information is to be confirmed.
And finally: - the most reliable symptoms are found when you use the source in the original language.
