Abstract
This critical notice was occasioned by the reading of a recent monograph, published at the end of 2009, which features a dialogue and a mutual critical assessment of the work of a microbiologist, also a priest from the Mission de France, and an astrophysicist who was agnostic. The book inquires into the motivations of scientific research, looks at the quest for a Creator behind the said work when done by a believer, and tries to retrieve the spiritual presuppositions that would be present at the heart of the same type of work when carried over without a religious affiliation or confession.
