See also the 2002 publication Liberty, edited by Henry Hardy, which incorporates Four Essays on Liberty, while adding to it a fifth essay, 'From Hope and Fear Set Free', which Berlin wished had been published in the 1969 edition. Liberty draws together key texts on this defining subject in Berlin's oeuvre, and in practical terms it supersedes Four Essays on Liberty.
