Battle Cry of Freedom: The Civil War Era

by James M. McPherson

This was a transformation from what the late Isaiah Berlin described as “Negative Liberty” to “Positive Liberty.”4 The idea of negative liberty is perhaps more familiar. It can be defined as the absence of restraint, a freedom from interference by outside authority with individual thought or behavior. A law requiring motorcyclists to wear a helmet would be, under this definition, to prevent them from enjoying the freedom to go bareheaded if they wish. Negative liberty, therefore, can be described as freedom from. Positive liberty can best be understood as freedom to . It is not necessarily incompatible with negative liberty, but has a different focus or emphasis. Freedom of the press is generally viewed as a negative liberty—freedom from interference with what a writer writes or a reader reads. But an illiterate person suffers from a denial of positive liberty; he is unable to enjoy the freedom to write or read whatever he chooses, not because some authority prevents him from doings so but because he cannot read or write anything. He suffers not the absence of a negative liberty—freedom from—but of a positive liberty—freedom to read and write. The remedy lies not in removal of restraint but in achievement of the capacity to read and write.
