The New Science (Italian: La Scienza Nuova) is a work by the Italian philosopher Giambattista Vico, originally published in 1725 and expanded in several later editions. It provides a history of civil society, interpreted, in opposition to contemporary Cartesian rationalism, through the principle of verum factum that what has been made by humans can be understood by humans.
Vico's account of human progress and his insight into the difference between ancient and modern ways of thinking has led many to credit him with being the first true philosopher of history.
