Liberalism in the broad sense accepts the individual as the basic unit of social analysis. Liberal thought opposes to all forms of oppression against the individual and demands economic, social, religious and political freedom. Liberalism, which is a kind of freedom theory, was born as a reaction to the old system in which various parts of the state and society could intervene in the rights and freedoms of the individual. While the left and socialism emphasize equality, liberalism emphasizes freedom. Liberalism is not just an economic doctrine; it is a multi-faceted ideology advocating certain basic views on the social and political sphere. In this context, liberalism is not collectivist but individualist; defends negative liberty far from positive freedom; calls for limited and responsible state, not an interventionist and oppressive state; believes in procedural justice based on market economy, against social justice based on redistribution.
