THE BLANK FACE OF LOVE: THE POSSIBILITY OF GOODNESS IN THE LITERARY AND PHILOSOPHICAL WORK OF IRIS MURDOCH1

This article explores the value of Iris Murdoch's metaphysical ethics for the theologian. Although, in many ways, Murdoch does appeal to the theologian, a subtle form of nihilism underlies her thought insofar as human goodness—in the form of loving attention—is only possible once the individual has overcome his/her ego by staring into the void and accepting the ultimate meaninglessness of reality. As this article demonstrates, Murdoch's replacement of transcendence with void rules out any form of real love or human goodness: only a dualistic exchange of gazes remains possible. Real, selfless love is only possible when the ego understands itself in the context of theological transcendence.     

A DEVELOPMENTAL-GENETIC ANALYSIS OF CONTINUITY AND CHANGE IN THE BAYLEY MENTAL DEVELOPMENT INDEX FROM 14 TO 24 MONTHS:

Abstract— A developmental-genetic model was fitted to Bayley Mental Development Index (MDI) data to address questions concerning the origins of individual differences in MDI performance and the origins of change and continuity during infancy More than 350 pairs of identical and same-sex fraternal twins were studied longitudinally at 14, 20, and 24 months of age There was substantial genetic continuity of general cognitive ability from 14 to 24 months but significant new genetic variation also appeared at 24 months Shared family environmental influences were global across all three ages and not time-specific Finally, nonshared environmental influences did not contribute to the observed continuity of general cognitive ability, only to change.
