What defines individual freedom in a civilised society? Philosophers have argued over such questions for centuries. This unit looks at various concepts of freedom, asking you to think carefully about how freedom is restricted by our place in society and how it can vary from state to state. This study unit is just one of many that can be found on LearningSpace, part of OpenLearn, a collection of open educational resources from The Open University.
