Abstract

This is the first English version of Geymonat's work since its publication in Italy in 1957. As the title suggests, it is more than a biography, for it records the vital interplay between the world of Galileo's thought and his vibrant personality. What gave direction to his life, according to Professor Geymonat, was the devotion to the task of "cultural propaganda," of making his radical discoveries palatable to the intellectual elite of the Catholic Church. That he took up this task, testifies to the scope of Galileo's imagination and to his understanding of the deep moral and cultural implications of the new science he was initiating. Professor Geymonat sees in Galileo's belief that experience and mathematical reasoning are commensurable and in his attachment to experiment more an Aristotelian reaction against the Church's perversion of Aristotle's thought, than a reversion to Platonism. Besides the complexity of Galileo's thought, the nobility and strength of a genius, struggling in his early years with financial and familial burdens, silenced in his prime by the censure of the Church, and incapacitated during his old age by sickness, shine through the pages of this book. There are extensive notes and two appendices on the as yet mysterious course of Galileo's second trial.—T. R. H.
