"The lives of scientists are a large part of the history of the human mind; it is the express history of its discoveries, of its inventions, of its sublime and creative ideas. Who knows this spectacle, and follow it carefully, he soon finds him one of the greatest. We see the human spirit moving forward, and we see the precious men to whom it owes its progress "(extract from the preface to Volume III).
