Negative liberty is freedom from interference by other people. Negative liberty is primarily concerned with freedom from external restraint and contrasts with positive liberty. The distinction originated with Bentham, was popularized by T. H. Green and Guido De Ruggiero, and is now best known through Isaiah Berlin's 1958 lecture "Two Concepts of Liberty".

Sir Isaiah Berlin was a Russian-British social and political theorist, philosopher, and historian of ideas. Although he became increasingly averse to writing for publication, his improvised lectures and talks were sometimes recorded and transcribed, and many of his spoken words were converted into published essays and books, both by himself and by others, especially by his principal editor from 1974, Henry Hardy.
