This study fills a notable gap in the history of political thought.

Originally published in 1978, this book examines how the states-system grew over generations, first within Europe, then world wide and how the idea of the state came to monopolise our vision of the world. It discusses the grounds for the division of humanity into separate states in reason and history and whether or not we can use terms like ‘obligation’ and ‘justice’ in seeking to understand our relations with people of other states.

An original work on the important idea of reason of state and British and imperial history and constitutional theory.

Niccolò Machiavelli's seminal work, The Prince, argued that a ruler could not govern morally and be successful. Giovanni Botero disputed this argument and proposed a system for the maintenance and expansion of a state that remained moral in character. Founding an anti-Machiavellian tradition that aimed to refute Machiavelli in practice, Botero is an important figure in early modern political thought, though he remains relatively unknown. His most notable work, Della ragion di Stato, first popularised the term 'reason of state' and made a significant contribution to a major political debate of the time - the perennial issue of the relationship between politics and morality - and the book became a political 'bestseller' in the late sixteenth and the seventeenth century. This translation of the 1589 volume introduces Botero to a wider Anglophone readership and extends this influential text to a modern audience of students and scholars of political thought.

Acclaimed writer and historian Noel Malcolm presents his sensational discovery of a new work by Thomas Hobbes (1588-1679): a propaganda pamphlet on behalf of the Habsburg side in the Thirty Years' War, translated by Hobbes from a Latin original. Malcolm's book explores a fascinating episode in seventeenth-century history, illuminating both the practice of early modern propaganda and the theory of "reason of state".

Natural Law, Constitutionalism, Reason of State, and War: Counter-Reformation Spanish Political Thought (Volumes I and II) aims at understanding how Spanish thinkers in the sixteenth and early seventeenth centuries approached the emerging institution of the state. The volumes are divided evenly into four distinct but related parts that cover the Spaniards' central concerns. In the first, a fundamental question is asked: Is the state a natural institution? In the second, the theme is the best form of government. The third part is concerned with the imperative need to define the ethical boundaries beyond which the state must not trespass. Finally, the fourth part examines the question of war as an instrument of policy.
