This is the first translation into English of Guicciardini's Dialogue on the Government of Florence. Written in the early 1520s by the author of the famous History of Italy, as well as a History of Florence and Political Maxims and Reflections, this dialogue presents what is arguably the most searching and comprehensive analysis of the politics of his times. Like Machiavelli, his contemporary and friend, Guicciardini rejects classical republican arguments in the name of the new political realism and acknowledges the important role of patronage and graft in contemporary politics and the illegitimacy of nearly all forms of political power. In this Dialogue he provides one of the clearest expositions of the term 'reason of state', which he was one of the first to employ and which he uses to justify the priority of state interest over private morality and religion.

Isaac Newton is one of the greatest scientists in history, yet the spectrum of his interests was much broader than that of most contemporary scientists. In fact, Newton would have defined himself not as a scientist, but as a natural philosopher. He was deeply involved in alchemical, religious, and biblical studies, and in the later part of his life he played a prominent role in British politics, economics, and the promotion of scientific research. Newton’s pivotal work Philosophiæ Naturalis Principia Mathematica, which sets out his laws of universal gravitation and motion, is regarded as one of the most important works in the history of science. Niccolò Guicciardini’s enlightening biography offers an accessible introduction both to Newton’s celebrated research in mathematics, optics, mechanics, and astronomy and to how Newton viewed these scientific fields in relation to his quest for the deepest secrets of the universe, matter theory and religion. Guicciardini sets Newton the natural philosopher in the troubled context of the religious and political debates ongoing during Newton’s life, a life spanning the English Civil Wars, the Restoration, the Glorious Revolution, and the Hanoverian succession. Incorporating the latest Newtonian scholarship, this fast-paced biography broadens our perception of both this iconic figure and the great scientific revolution of the early modern period.

This book demonstrates that geohistory is a more effective concept than geopolitics in understanding inter-state relations, at a time of considerable confusion in world affairs, and that Francesco Guicciardini’s thoughts are an efficient medium to demonstrate not only the inadequacies of geopolitics, but that a geohistorical approach can be a more responsible way of understanding international affairs. The book introduces a fresh approach, based on the individual, on which corporate characteristics and behaviour depend, often in the shape of state interests, which are unable on their own to predict actions driven by human behaviour. The book shows how show mainstream international relations theories are stuck in paradigms, inadequate in explaining why world politics is moving in a direction that nobody could predict even a decade ago. It shows how ideology can blur clear understanding. In short, it represents a new and intellectually refreshing approach and method in understanding, and tackling, the vagaries of relations between states.

In Felix Gilbert's skilled analysis, the figures of Niccolo Machiavelli, whose writing changed the way people think about politics, and Francesco Guicciardini, whose History of Italy is one of the first classics of modern historical writing, provide important clues to interpreting the Renaissance.
