Definition of Liberalism and Nationalism
Liberalism is a political philosophy based on belief in progress, the essential goodness of the human race, and the autonomy of the individual and standing for the protection of political and civil liberties.
Nationalism is a sense of national consciousness exalting one nation above all others and placing primary emphasis on the promotion of its culture and interests as opposed to those of other nations or supranational groups.
How they both are different?
Nationalism may take various forms but essentially, it is about collective identity, whereas liberalism implies the defence of individual freedom and self-determination.
Liberalism can underpin universal rights and Adam Smith’s natural laws of economics. But its appeal is mainly to the professional, educated class and lacks nationalism’s emotional appeal.
