“Galileo’s Daughter – a drama of science, faith and love” by Dava Sobel. Fourth Estate, London 2000 (1999) pages 429
This review was written in December 2004 and amended in January 2005.
This paperback is described as “completely unputdownable” by a reviewer. If for no other reason but as the story of one of the world’s great geniuses, it is certainly essential reading for those seeking a knowledge of European history, the role of the Vatican and the march of science. Sobel uses the correspondences between Maria Celeste Galilei, the older daughter of Galileo Galilei, to her father as the background to the lifetime and achievements of Galileo himself. Galileo never married but had three children, two girls and a boy, by Marena Gamba who subsequently married somebody else! Galileo was born in 1564 and died January 1642. His two daughters entered a convent near Florence where they were incarcerated largely because of their illegitimacy. The boy Vincenzio was legitimised by the Grand Duke of Tuscany in 1619, having been born in 1606.
The book gives a good background to life in Northern and Central Italy during the late 16th and early 17th Centuries. It underlines the huge influence of the Vatican in the political, social and spiritual life of the people. Life was cheap then thanks to recurring epidemics of plague and to various other ill defining fevers which must have included malaria, TB, typhoid, smallpox and other less common infections. Galileo was not immune and suffered many illnesses and disabilities during his lifetime. Although he lived to the age of 78, many others included in the elaborate family tree published in the book failed to reach the age of 50.
Whilst the book is a detailed account of the relationship between Galileo and his older daughter, the substance of the book portrays what a remarkable person Galileo was at a time when the world was guided largely by superstition and tradition, and when there was little evidence of a scientific approach to natural phenomena.
Galileo might well have been a 20th Century scientist with all the energy, the insights, the serendipity and the enquiring mind of one of our leading inventors. He was first noted for his major advances to the telescope which allowed him to see into space to study the stars and he invented many other useful gadgets and made huge contributions to the knowledge of astronomy and of the physical phenomena of motion and of measurement. He remained a fervent Catholic all his life but was probably one of the first to disagree with the Church’s dogma that scripture determined the form and the function of the natural world and that anything which was contrary to scripture was a form of heresy.
The critical situation facing Galileo was the question of the centrality of the earth in the Universe. Copernicus had published the view that the sun was the centre, at least of the planetary system, although he provided no definite proof of such a concept. Indeed, far back in Greek and Egyptian times the centrality of the earth was doubted by some observers. Galileo went further than Copernicus by providing some astronomical evidence to confirm the centrality of the sun, but his views were to lead him into serious trouble with the Vatican and particularly with his old friend Pope Urban VIII who became his implacable foe on the issue.
|Pope Urban VIII|
Clearly when Urban VIII became so implacably opposed to Galileo he must have been influenced by some of Galileo’s enemies. Like all innovators and advanced thinkers, Galileo had many enemies, both within the clergy and among the less enlightened laity, including some resentful and jealous colleagues. While he met much opposition and bitterness in his own country, his work was greatly admired and accepted by scientists in Holland, Germany, Switzerland and the more advanced and less bible committed countries.
|Maria Celeste Galilei|
It may seem a step from the sublime to the ridiculous when I recall my own experience of denial, indifference and hostility during my own professional career. On the one hand I was almost alone on these Islands in the 1960s in advocating risk factor identification and modification as a rational basis for the treatment and rehabilitation of coronary patients, while the rest of my cardiological colleagues confined their treatment regimes to drugs, surgery and angioplasty. It is only in recent years that cardiologists have begun to pay attention to the fundamental need to seek out causes of arterial disease and to deal with such causes vigorously, not only in the healthy population but also in patients who suffer from coronary disease. The same indifference and covert hostility was evident among my colleagues during the early years when I was advocating in public the importance of cigarette smoking control, healthy nutrition and the value of exercise in maintaining physical and psychological health. We have seen over the past 50 years or more huge advances in diagnosis and treatment but at the same time we have seen an excessive emphasis on therapeutic and invasive intervention and a general neglect of causation and of a natural approach to prevention and to encouraging the healing powers of nature by natural means.
The Roman Church’s conflict with Galileo and his condemnation by the Inquisition can only be ascribed to ignorance, superstition and the abuse of power. Nowhere in the book does the author say that the Church accepted the truth of the centrality of the Sun. It was only very recently that the Vatican officially accepted the concept put forward by Galileo
