Abstract
In the modern period, the most original and influential theories about law and politics were developed in connection with a set of far-reaching, interrelated questions about the definition of law, the purpose of law, the relationship between law and morality, and the existence of natural law and natural rights. In this entry I summarize the contributions of Charles-Louis de Secondat, Baron de La Brède et de Montesquieu; William Blackstone; Jeremy Bentham; and Immanuel Kant as exemplars of the history of modern thought on law and politics.
