Liberalism (from Encyclopedia of Politics: The Left and the Right)Historical, or classical liberalism, has been used to describe both a political and an economic school of thought. Classical liberalism was based on the assumption that human beings are rational, granting them the right to make decisions for themselves. Classical liberals also believed that government had a responsibility to provide public works and services that individuals could not provide for themselves. modern liberals, embodied chiefly in the Democratic party, have extended the emphasis on individuals to encompass a strong sense of social justice, a demand for social reforms, and a belief that human beings have a right to basic human dignity.
