Abstract

In the early 1950s, astronomer Allan Sandage inherited from Edwin Hubble the task of determining whether expansion was real. In the succeeding forty years, Sandage “established the discipline of observational cosmology” (Overbye 1991, 188). At the same time, he encountered the limits of science to address the full mystery of existence. In seeking an answer to the question of purpose, in particular, Sandage came to the “abyss of reason” and made the “leap of faith.” This conversion, however, involved, and continues to involve, an ongoing process of balancing two avenues to the truth, drawing upon resources from both scientific and religious traditions. Reason and faith seem reconcilable in life lived as an experiment and in “bowing before the mystery” (Sandage 1990). Ultimately, Sandage suggests that religious conversion comes not so much through reasoned pursuit as in the realization of being pursued.
