Progressivism is a political philosophy and movement that seeks to advance the human condition through social reform – primarily based on purported advancements in social organization, science, and technology. Adherents hold that progressivism has universal application and endeavor to spread this idea to human societies everywhere. Progressivism arose during the Age of Enlightenment out of the belief that civility in Europe was improving due to the application of new empirical knowledge.
