Progressivism is a philosophy based on the Idea of Progress, which asserts that advancements in science, technology, economic development, and social organization are vital to the improvement of the human condition. Progressivism became highly significant during the Age of Enlightenment in Europe, out of the belief that Europe was demonstrating that societies could progress in civility from barbaric conditions to civilization through strengthening the basis of empirical knowledge as the foundation of society. Figures of the Enlightenment believed that progress had universal application to all societies and that these ideas would spread across the world from Europe. Sociologist Robert Nisbet defines five "crucial premises" of the Idea of Progress as being: value of the past; nobility of Western civilization; worth of economic/technological growth; scientific/scholarly knowledge obtained through reason over faith; the intrinsic importance and worth of life on Earth. Beyond this, the meanings of progressivism have varied over time and from different perspectives.
The contemporary common political conception of progressivism in the culture of the Western world emerged from the vast social changes brought about by industrialization in the Western world in the late 19th century, particularly out of the view that progress was being stifled by vast economic inequality between the rich and the poor; minimally regulated laissez-faire capitalism with monopolistic corporations; and intense and often violent conflict between workers and capitalists, thus claiming that measures were needed to address these problems.
