AbstractPhenomenologically grounded research on pregnancy is a thriving area of activity in feminist studies and related disciplines. But what has been largely omitted in this area of research is the experience of childbirth itself. This paper proposes a phenomenological analysis of childbirth inspired by the work of Merleau-Ponty. The paper proceeds from the conviction that the concept of anonymity can play a critical role in explicating the affective structure of childbirth. This is evident in at least two respects. First, the concept of anonymity gives structural specificity to the different levels of bodily existence at work in childbirth. Second, the concept of anonymity can play a powerful explanatory role in accounting for the sense of strangeness accompanying childbirth. To flesh these ideas out, I focus on two attributes of birth, sourced from first-person narratives of childbirth. The first aspect concerns the sense of leaving one’s body behind during childbirth while the second aspect concerns the sense of strangeness accompanying the first encounter with the baby upon successful delivery. I take both of these aspects of childbirth seriously, treating them as being instructive not only of the uniqueness of childbirth but also revealing something important about bodily life more generally. Accordingly, the paper unfolds in three stages. First, I will critically explore the concept of anonymity in Merleau-Ponty; second, I will apply this concept to childbirth; finally, I will provide an outline of how childbirth sheds light on the broader nature of bodily life.

The ability of fragments of incisor enamel organ and lip-furrow epithelium from 15- and 16-day old embryonic mice to regulate into harmonious tooth constructions is described. The cervical loop and upper half portions of the incisor enamel organ were confronted with incisor or molar dental papillae. Similar combinations were made from lip-furrow epithelium and incisor or molar papillae. The cultures were grown in the anterior chambers of homologous host eyes. The epithelial fragments from the incisor enamel organ when associated with the dental papillae reconstruct teeth typical in all respects; enamel and dentin matrices are deposited. Lip-furrow epithelium arises from the oral epithelium and is temporally and spatially related to the incisor dental epithelium proper. This ectopic epithelium was confronted by incisor and molar papillae. Harmonious teeth developed in these explants. It is concluded that the ability of the dental papillae to elicit new cytodifferentiative and biochemical syntheses from the lip-furrow epithelium indicates that the dental papillae act inductively during tooth ontogeny. The shape of the teeth reconstructed from enamel organ fragments and lip-furrow epithelium were incisiform or molariform in response to the incisor or molar dental papillae. These data confirm the conclusion that the structural specificity for tooth shape resides in the dental papilla.

Studies of epithelio-mesenchymal interactions during embryonic organogenesis have led to a number of conclusions regarding the nature of cellular and tissue differentiation (McLoughlin, 1963; Grobstein, 1967). For example, the importance of both the epithelium and the mesenchyme and the dependence of some systems on a limited number of specific mesenchymal tissues have been pointed out (Hilfer, 1968). Intimately connected with the analysis of the factors that elicit differentiation during such interactions is the question of structural specificity of the differentiated structure. Is the directive for the final form of the structure resident in the epithelium, in the mesoderm, or in both? Can a seemingly stable epithelium undergo transformation to a more labile state and respond to a new interaction with the result that a new epithelial structure is formed (Billingham & Silvers, 1963, 1968)?
