On the occasion of the publication, in March 1987, of the Catholic Church’s condemnation of in vitro fertilisation, surrogate motherhood, and foetal experimentation, there appeared a cartoon in a Roman newspaper, in which two bishops are standing next to a telescope. In the distant night sky, in addition to Saturn and the Moon, there are dozens of test-tubes. One bishop turns to the other, who is in front of the telescope, and asks: ‘This time what should we do? Should we look or not?’ Many see the Galileo affair as a prime example of the fundamental incompatibility between science and religion, between reason and faith. Stephen Hawking, in his recent best-seller, A Brief History of Time, writes a two-page biographical appendix on Galileo which offers ample evidence for the persistence of the view that the accomplishments of Galileo must be understood in the face of the opposition of Aristotelian science and Catholic theology. Galileo, Hawking claims, ‘was one of the first to argue that man could hope to understand how the world works, and, moreover, that we could do this by observing the real world.’ Hawking, in commenting on his participation at a conference on cosmology sponsored by the Vatican at which he challenged traditional interpretations of Big Bang cosmology, evoked the image of himself as a potential Galileo:

The Catholic Church had made a bad mistake with Galileo when it tried to lay down a law on a question of science, declaring that the sun went around the earth. Now, centuries later, it had decided to advise it on cosmology.

12 In a recent work, Galileo eretico, Pietro Redondi, claims that it was precisely Galileo's commitment to atomism, as found in The Assayer, that was the real source of his troubles with the Church. Despite Redondi's many insights concerning the theological and philosophical world in which the trial occurred, his specific thesis that the dispute concerning the relationship between Copernican astronomy and the Bible was part of a shadow theatre which concealed the serious dispute over Eucharistic theology is hardly satisfactory.
