Since then liberalism has broadened to include a wide range of approaches from Americans Ronald Dworkin, Richard Rorty, John Rawls and Francis Fukuyama as well as the Indian Amartya Sen and the Peruvian Hernando de Soto. Some of these people moved away from liberalism while others espoused other ideologies before turning to liberalism. There are many different views of what constitutes liberalism, and some liberals would feel that some of the people on this list were not true liberals. It is intended to be suggestive rather than exhaustive. Theorists whose ideas were mainly typical for one country should be listed in that country's section of liberalism worldwide. Generally only thinkers are listed whereas politicians are only listed when they also made substantial contributions to liberal theory beside their active political work.
