You have to connect your work to what people are doing. A good way is to construct a bridge between theory and practice - Amartya Sen and I tried this by founding the Human Development and Capabilities Association where practitioners meet theoreticians and their discourse influences practice.
Hilary Putnam died of cancer at the age of 89. Those of us who had the good fortune to know Putnam as mentees, colleagues, and friends remember his life with profound gratitude and love, since Hilary was not only a great philosopher, but also a human being of extraordinary generosity, who really wanted people to be themselves, not his acolytes.
Look at the great tradition of Western political philosophy. Those people were all immersed in revolutionary movements. Most weren't career academics - often, they were too radical to be accepted in the academy. Rousseau's books were banned. Jeremy Bentham and John Stuart Mill couldn't hold academic positions because they were atheists.
I think we've lost the idea that politicians are part of the humanities. And we think of them as part of a natural science tradition, and we don't expect them to have the contact with literature, with history, with the richness of descriptive language that the humanities have always stood for. And I think that's a great loss.
