This paper presents an account of how human spontaneous embryonic chimeras are formed. On the prevalent view in the philosophical literature, it is said that chimeras are the product of two embryos that fuse to form a new third embryo. We call this version of fusion synthesis. In contrast to synthesis, we present an alternative mechanism for chimera formation called incorporation, wherein one embryo incorporates the cells of a second embryo into its body. We argue that the incorporation thesis explains other types of chimera formation, which are better understood, and is more consistent than synthesis with what is known about embryological development. Incorporation also has different implications than synthesis and so avoids the philosophical puzzles that are often said to accompany embryonic chimera formation—puzzles which pose problems to the human embryo’s persistence from fertilization to the fetal stage of human development.  相似文献

An uncritical analysis of the empirical Rorschach literature in the area of suicide could lead one to conclude that the test has little value for the identification, prediction and understanding of suicide. It was felt that the reasons for this could be related to the several inconsistencies in methodology and design found among the studies. The research data were classified into four groups (1) determinants and ratios, (2) single signs, (3) multiple signs, and (4) content, and reviewed from a methodological standpoint. From this analysis it was concluded that there was no specific pathognomic sign for suicide on the Rorschach. It was also pointed out that certain difficulties (“paper” investigations, and research conditions which mediate against significance at the .05 level) reduce the effectiveness of the Rorschach investigator. Certain methodological and design weaknesses were discussed in terms of their contributing to equivocality among the studies. Comparisons between the studies cited were difficult to make because of their differing experimental designs and operational definitions of suicide. Because of this, the Rorschach itself cannot be held culpable for the equivocal results.  相似文献

Abstract

This study1 explores the experience of the body for contemporary female mystics. It is an exploration in how women mystics of today—those who have devoted most of their lifetime to prayer, meditation, and spiritual service—make sense of the body. What is the relationship between spirit and body, God and flesh, for such women? Is it a relationship of tension or even opposition, and how does it evolve over time? These are some of the questions that guided my investigation. The impulse to understand how the body is experienced and understood by such women was felt by me as both a longing to challenge, deepen, and refine my awareness and understanding of spirit and the body, specifically for women mystics. I also felt this as a burning in the heart, an urgent desire to connect and bridge the larger world of matter and that of spirit, to inquire into that dimension where flesh and spirit are not two, but one. I believe that this impulse to understand the relationship between body and spirit is both personal and quite possibly collective. My hope is that this research will serve as one step to further our collective understanding of human embodiment.  相似文献
