This chapter explores, together, human unfreedom alongside the potential freedom itself offers for a theory of justice. Isaiah Berlin is often credited with establishing the importance of pluralism in liberal thought and, indeed, his remarkable and enduring essay, Two Concepts of Liberty makes a compelling and moving defence of the basic idea that 'the ends of men are many', set against the tragic backdrop of the mid-twentieth century, which so clearly and naturally informed Berlin's work. Empathy helps to cognitively transfer the thought behind the golden rule onto others. Radical concern is a means of becoming acquainted with how freedom is lived, and how unfreedom is lived, amongst the environments, structures and atmospheres of the modern world, beyond the kind of theoretical disputes. There is a deep and profound emotional side to human freedom and to human unfreedom.
