Artigo de Birthmarks

Nota: Este artigo do Dr. Ian Stevenson, publicado em uma revista acadêmica em 1993, fornece incríveis evidências gráficas de que os traços físicos podem, de alguma forma, passar de uma vida passada para uma vida presente. Também fornece uma amostra da minúcia do Dr. Stevenson e de seu estilo acadêmico. Não é uma leitura fácil. Mas é, na minha opinião, a prova mais forte ainda de reencarnação.
O "próximo livro" mencionado pelo Dr. Stevenson e no qual este artigo se baseia está agora disponível. É enorme, mais de 2200 páginas. Se você quiser aprofundar esse trabalho incrível, recomendo que você obtenha o livro de resumo mais curto, Onde Biologia e Reencarnação se Intersectam da Amazon.com (provavelmente não está na sua livraria local, mas está aqui na nossa).
A seguir, o texto completo do artigo.

 

"Marcas de nascença e defeitos de nascimento correspondentes a feridas em pessoas falecidas"

Por Dr. Ian Stevenson

O Dr. Ian Stevenson é o chefe do Departamento de Medicina Psiquiátrica da Escola de Medicina da Universidade da Virgínia, Charlottesville, Virgínia.
Este artigo foi apresentado na Décima Primeira Reunião Anual da Sociedade de Exploração Científica, realizada na Universidade de Princeton. 11-13 de junho de 1992.

Abstrato

Quase nada se sabe sobre por que as marcas de nascença pigmentadas (pintas ou nevos) ocorrem em locais específicos da pele. As causas da maioria dos defeitos congênitos também são desconhecidas. Cerca de 35% das crianças que afirmam se lembrar de vidas anteriores têm marcas de nascença e / ou defeitos de nascença que eles (ou informantes adultos) atribuem a feridas em uma pessoa cuja vida a criança se lembra. Os casos de 210 crianças foram investigados. As marcas de nascença eram geralmente áreas de pele sem pelos e enrugada; alguns eram áreas com pouca ou nenhuma pigmentação (máculas hipopigmentadas); outros eram áreas de aumento da pigmentação (nevos hiperpigmentados). Os defeitos de nascimento eram quase sempre de tipos raros. Nos casos em que uma pessoa falecida foi identificada, os detalhes de cuja vida inconfundivelmente correspondeu às declarações da criança, quase sempre foi encontrada uma correspondência estreita entre as marcas e / ou defeitos de nascimento na criança e os ferimentos na pessoa falecida. Em 43 dos 49 casos em que um documento médico (geralmente um relatório post-mortem) foi obtido, confirmou a correspondência entre feridas: e marcas de nascença (ou defeitos de nascimento). Há pouca evidência de que os pais e outros informantes tenham imposto marcas falsas de identificação e defeitos congênitos à criança, a fim de explicar a marca ou defeito de nascença. Algum processo paranormal parece necessário para explicar pelo menos alguns dos detalhes desses casos, incluindo o nascimento e marcas de nascença (ou defeitos de nascença).

Introdução

Embora a contagem de moles (nevos hiperpigmentados) tenha mostrado que o adulto médio tem entre 15 e IX (Pack e Davis, 1956), pouco se sabe sobre sua causa - exceto aqueles associados à doença genética neurofibromatose - e até Sabe-se menos sobre por que as marcas de nascença ocorrem em um local do corpo e não em outro. Em alguns casos, um fator genético foi plausivelmente sugerido para a localização de nevos (Cockayne, 1933; Denaro, 1944; Maruri, 1961); mas a causa da localização da maioria das marcas de nascença permanece desconhecida. As causas de muitos, talvez da maioria, defeitos congênitos permanecem igualmente desconhecidas. Em grandes séries de defeitos congênitos em que os pesquisadores pesquisaram as causas conhecidas, como teratógenos químicos (como a talidomida), infecções virais e fatores genéticos, entre 430/0 (Nelson e Holmes,
Entre 895 casos de crianças que alegaram se lembrar de uma vida anterior (ou que os adultos pensavam ter uma vida anterior), marcas de nascença e / ou defeitos de nascença atribuídos à vida anterior foram relatados em 309 (35%) dos indivíduos. Dizia-se que a marca ou defeito de nascença da criança correspondia a uma ferida (geralmente fatal) ou outra marca na pessoa falecida cuja vida a criança disse que se lembrava. Este artigo reporta uma investigação sobre a validade de tais reivindicações. Com meus associados, levei a investigação de 210 casos a um estágio em que posso relatar seus detalhes em um livro futuro (Stevenson, a ser publicado). Este artigo resume nossas descobertas.
Crianças que afirmam se lembrar de vidas anteriores foram encontradas em todas as partes do mundo em que foram procuradas (Stevenson, 1983; 1987), mas são encontradas com mais facilidade nos países do sul da Ásia. Normalmente, essa criança começa a falar sobre uma vida anterior quase tão logo quanto pode falar, geralmente entre os dois e os três anos de idade; e normalmente deixa de fazê-lo entre os cinco e os sete anos de idade (Cook, Pasricha, Samararatne, Win Maung e Stevenson, 1983). Embora algumas crianças façam apenas declarações vagas, outras fornecem detalhes de nomes e eventos que permitem identificar uma pessoa cuja vida e morte correspondem às declarações da criança. Em alguns casos, a pessoa identificada já é conhecida pela família da criança, mas em muitos casos isso não é verdade. Além de fazer declarações verificáveis ​​sobre uma pessoa falecida,
Embora algumas das marcas de nascença nessas crianças sejam nevos hiperpigmentados "comuns", dos quais todo adulto tem alguns (Pack e Davis, 1956), a maioria não. Em vez disso, eles são mais propensos a ficar enrugados e com cicatrizes, às vezes deprimidos um pouco abaixo da pele ao redor, áreas sem pêlos, áreas de pigmentação acentuadamente diminuída (máculas hipopigmentadas) ou manchas de vinho do porto (nevipammri). Quando uma marca de nascença relevante é um nevo hiperpigmentado, é quase sempre maior em área do que o nevo hiperpigmentado "comum". Da mesma forma, os defeitos congênitos nesses casos são de tipos incomuns e raramente correspondem a qualquer um dos "padrões reconhecíveis de malformação humana" (Smith, 1982).

Métodos

My investigations of these cases included interviews, often repeated, with the subject and with several or many other informants for both families. With rare exceptions, only firsthand informants were interviewed. All pertinent written records that existed, particularly death certificates and postmortem reports, were sought and examined. In the cases in which the informants said that the two families had no previous acquaintance, I made every effort to exclude all possibility that some information might nevertheless have passed normally to the child, perhaps through a half-forgotten mutual acquaintance of the two families. I have published elsewhere full details about methods (Stevenson, 1975; 1987).
I did not accept any indicated mark as a birthmark unless a firsthand witness assured me that it had been noticed immediately after the child's birth or, at most, within a few weeks. I enquired about the occurrence of similar birth marks in other members of the family; in nearly every instance this was denied, but in seven cases a genetic factor could not be excluded.
Birth defects of the kind in question here would be noticed immediately after the child's birth. Inquiries in these cases excluded (again with rare exceptions) the known causes of birth defects, such as close biological relationship of the parents (consanguinity), viral infections in the subject's mother during her pregnancy, and chemical causes of birth defects like alcohol.

Correspondences between Wounds and Birthmarks

A correspondence between birthmark and wound was judged satisfactory if the birthmark and wound were both within an area of 10 square centimeters at the same anatomical location; in fact, many of the birthmarks and wounds were much closer to the same location than this. A medical document, usually a postmortem report, was obtained in 49 cases. The correspondence between wound and birthmark was judged satisfactory or better by the mentioned criterion in 43 (88%) of these cases and not satisfactory in 6 cases. Several different explanations seem to be required to account for the discrepant cases, and I discuss these elsewhere (Stevenson. forthcoming). Figure 1 shows a birthmark (an urea of hypopigmentation) on an Indian child who said he remembered the life of a man who had been killed with a shotgun fired at close range. Figure 2 shows the location of the wounds recorded by the pathologist. (The circles were drawn by an Indian physician who studied the postmortem report with me.)
The high proportion (88%) of concordance between wounds and birthmarks in the cases for which we obtained postmortem reports (or other confirming documents) increases confidence in the accuracy of informants' memories concerning the wounds on the deceased person in those more numerous cases for which we could obtain no medical document. Not all errors of informants memories would have resulted in attributing a correspondence between birth marks and wounds that did nor exist; in four cases (possibly five) reliance on an informant's memory would have resulted in missing a correspondence to which a medical document attested.

Cases with Two or More Birthmarks

The argument of chance as accounting for the correspondence between birthmarks and wounds becomes much reduced when the child has two or more birthmarks each corresponding to a wound on the deceased person whose life he claims to remember. Figure 3 shows a major abnormality of the skin (verrucous epidermal nevus) on the back of the head of a Thai man who, as a child, recalled the life of his uncle, who had been struck on the head with a heavy knife and killed almost instantly. The subject also had a deformed toenail of the right great toe (Figure 4). This corresponded to a chronic infection of the same toe from which the subject's uncle had suffered for some years before he died.

The series includes 18 cases in which two birthmarks on a subject corresponded to gunshot wounds of entry and exit. In 14 of these one birthmark was larger than the other, and in 9 of these 14 the evidence clearly showed that the smaller birthmark (usually round) corresponded to the wound of entry and the larger one (usually irregular in shape) corresponded to the wound of exit. These observations accord with the fact that bullet wounds of exit are nearly always larger than wounds of entry (Fatteh, 1976; Gordon and Shapiro, 1982). Figure 5 shows a small round birthmark on the back of the head of a Thai boy, and Figure 6 shows a larger, irregularly shaped birthmark at the front of his head. The boy said that he remembered the life of a man who was shot in the head from behind. (The mode of death was verified, but no medical document was obtainable.) In addition to the 9 cases I have investigated myself, Mills reported another case having the feature of a small round birthmark (corresponding to the wound of entry) and a larger birthmark corresponding to the wound of exit (both verified by a postmortem report) (Mills, 1989).

Larger, irregularly shaped birthmark on the frontal area of the head of the Thai boy shown in Figure 5. This birthmark corresponded to the bullet wound of exit on the Thai man whose life the boy said he remembered.
I have calculated the odds against chance of two birthmarks correctly corresponding to two wounds. The surface area of the skin of the average adult male is 1.6 meters (Spalteholz, 1943). If we were to imagine this area square and spread on a fiat surface, its dimensions would be approximately 127 centimeters by 127 centimeters. Into this area would fit approximately 160 squares of the size 10 centimeters square that I mentioned above. The probability that a single birthmark on a person would correspond in location to a wound within the area of any of the 160 smaller squares is only 1/160. However, the probability of correspondences between two birthmarks and two wounds would be (1/160)2 i.e. 1 in 25,600. (This calculation assumes that birthmarks are uniformly distributed over all regions of the skin. This is incorrect [Pack, Lenson, and Gerber, 1952], but I believe the variation can be ignored for the present purpose.)

Examples of Other Correspondences of Detail between Wounds and Birthmarks

A Thai woman had three separate linear hypopigmented scarlike birthmarks near the midline of her back; as a child she had remembered the life of a woman who was killed when struck three times in the back with an ax. (Informants verified this mode of death, but no medical record was obtainable.) A woman of Burma was born with two perfectly round birthmarks in her left chest; they slightly overlapped, and one was about half the size of the other. As a child she said that she remembered the life of a woman who was accidentally shot and killed with a shotgun. A responsible informant said the shotgun cartridge had contained shot of two different sizes. (No medical record was obtainable in this case.)
Another Burmese child said that she remembered the life of her deceased aunt, who had died during surgery for congenital heart disease. This child had a long, vertical linear hypopigmented birthmark close to the midline of her lower chest and upper abdomen; this birthmark corresponded to the surgical incision for the repair of the aunt's heart. (I obtained a medical record in this case.) In contrast, a child of Turkey had a horizontal linear birthmark across the right upper quadrant of his abdomen. It resembled the scar of a surgeon's transverse abdominal incision. The child said that he remembered the life of his paternal grandfather, who had become jaundiced and was operated on before he died. He may have had a cancer of the head of the pancreas, but I could not learn a precise medical diagnosis.
Two Burmese subjects remembered as children the lives of persons who had died after being bitten by venomous snakes, and the birthmarks of each corresponded to therapeutic incisions made at the sites of the snakebites on the persons whose lives they remembered. Another Burmese subject also said as a child that she remembered the life of a child who had been bitten on the foot by a snake and died. In this case, however, the child's uncle had applied a burning cheroot to the site of the bite -- a folk remedy for snakebite in parts of Burma; and the subject's birthmark was round and located at the site on the foot where the bitten child's uncle had applied the cheroot.

Three Examples of Birth Defects

Figure 8, below, shows the right side of the head of a Turkish boy with a diminished and malformed ear (unilateral microtia). He also had underdevelopment of the right side of his face (hemifacial microsomia). He said that he remembered the life of a man who had been shot (with a shotgun) at point-blank range. The wounded man was taken to a hospital where he died 6 days later -- of injuries to the brain caused by shot that had penetrated the right side of the skull. (I obtained a copy of the hospital record.)

Figure 9 shows fingers almost absent congenitally on one hand (unilateral brachydactyly) in a child of India who said he remembered the life of another child who had put his right hand into the blades of a fodder-chopping machine and lost his fingers. Most cases of brachydactyly involve only a shortening of the middle phalanges. In the present case there were no phalangeal bones, and the fingers were represented by mere stubs. Unilateral brachydactyly is exceedingly rare, and I have not found a published report of a case, although a colleague (plastic surgeon) has shown me a photograph of one case that came under his care.

Almost absent fingers (brachydactyly) on one hand in a boy of India who said he remembered the life of a boy of another village who had put his hand into the blades of a fodderchopping machine and had its fingers amputated.
 
Figure 10 shows congenital absence of the lower right leg (unilateral hemimelia) in a Burmese girl. She said that she remembered the life of a girl who was run over by a train. Eyewitnesses said that the train severed the girl's right leg first, before running over the trunk. Lower hemimelia is an extremely rare condition, and Frantz and O'Rahilly (1961) found it in only 12 (4.0%) of 300 cases of all congenital skeletal deficiencies that they examined.

Discussion

Because most (but not all) of these cases develop among persons who believe in reincarnation, we should expect that the informants for the cases would interpret them as examples according with their belief; and they usually do. It is necessary, however, for scientists to think of alternative explanations.
The most obvious explanation of these cases attributes the birthmark or birth defect on the child to chance, and the reports of the child's statements and unusual behavior then become a parental fiction intended to account for the birthmark (or birth defect) in terms of the culturally accepted belief in reincarnation. There are, however, important objections to this explanation. First, the parents (and other adults concerned in a case) have no need to invent and narrate details of a previous life in order to explain their child's lesion. Believing in reincarnation, as most of them do, they are nearly always content to attribute the lesion to some event of a previous life without searching for a particular life with matching details. Second, the lives of the deceased persons figuring in the cases were of uneven quality both as to social status and commendable conduct. A few of them provided models of heroism or some other enviable quality; but many of them lived in poverty or were otherwise unexemplary. Few parents would impose an identification with such persons on their children. Third, although in most cases the two families concerned were acquainted (or even related), I am confident that in at least 13 cases (among 210 carefully examined with regard to this matter) the two families concerned had never even heard about each other before the case developed. The subject's family in these cases can have had no information with which to build up an imaginary previous life which, it later turned out, closely matched a real one. In another 12 cases the child's parents had heard about the death of the person concerned, but had no knowledge of the wounds on that person. Limitations of space for this article oblige me to ask readers to accept my appraisal of these 25 cases for this matter; but in my forthcoming work I give a list of the cases from which readers can find the detailed reports of the cases and from reading them judge this important question for themselves. Fourth, I think I have shown that chance is an improbable interpretation for the correspondences in location between two or more birthmarks on the subject of a case and wounds on a deceased person.
Persons who reject the explanation of chance combined with a secondarily confected history may consider other interpretations that include paranormal processes, but fall short of proposing a life after death. One of these supposes that the birthmark or birth defect occurs by chance and the subject then by telepathy learns about a deceased person who had a similar lesion and develops an identification with that person. The children subjects of these cases, however, never show paranormal powers of the magnitude required to explain the apparent memories in contexts outside of their seeming memories.
Another explanation, which would leave less to chance in the production of the child's lesion, attributes it to a maternal impression on the part of the child's mother. According to this idea, a pregnant woman, having a knowledge of the deceased person's wounds, might influence a gestating embryo and fetus so that its form corresponded to the wounds on the deceased person. The idea of maternal impressions, popular in preceding centuries and up to the first decades of this one, has fallen into disrepute. Until my own recent article (Stevenson, 1992) there had been no review of series of cases since 1890 (Dabney, 1890); and cases are rarely published now (Williams and Pembroke, 1988). Nevertheless, some of the published cases -- old and new -- show a remarkable correspondence between an unusual stimulus in the mind of a pregnant woman and an unusual birthmark or birth defect in her later-born child. Also, in an analysis of 113 published cases I found that the stimulus occurred to the mother in the first trimester in 80 cases (Stevenson, 1992). The first trimester is well known to be the one of greatest sensitivity of the embryo/fetus to recognized teratogens, such as thalidomide (Nowack, 1965) and rubella (Hill, Doll, Galloway, and Hughes, 1958). Applied to the present cases, however, the theory of maternal impression has obstacles as great as the normal explanation appears to have. First, in the 25 cases mentioned above, the subject's mother, although she may have heard of the death of the concerned deceased person, had no knowledge of that person's wounds. Second, this interpretation supposes that the mother not only modified the body of her unborn child with her thoughts, but after the child's birth influenced it to make statements and show behavior that it otherwise would not have done. No motive for such conduct can be discerned in most of the mothers (or fathers) of these subjects.
It is not my purpose to impose any interpretation of these cases on the readers of this article. Nor would I expect any reader to reach even a preliminary conclusion from the short summaries of cases that the brevity of this report entails. Instead, I hope that I have stimulated readers to examine the detailed reports of many cases that I am now in the process of publishing (Stevenson, forthcoming). "Originality and truth are found only in the details" (Stendhal, 1926).
