The purpose of this study is to examine the possibilities of patriotism education in a multicultural nation where diverse groups of national, ethnical and cultural backgrounds coexist as citizens of one nation. I first examined arguments for and against the possibility and desirability of patriotism education. There are some strong arguments against the moral credentials of patriotism, and against the educational desirability of promoting patriotism. However many scholars distinguish various types of or approaches to patriotism and then ague that whereas some forms of patriotism, such as nationalistic, blind, loyal, and uncritical patriotism are unjustifiable and even harmful, patriotism can be regarded as a moral virtue (or the moral virtue) and legitimate concern of public education in so far as it is treated in appropriate manners. I argue that, if patriotism is understood as positive and affectionate attitudes towards and prides in the ‘national identity’, patriotism education is important both for the individuals’ social-psychological development and for the nation’s cohesion and security. Two critical issues raised from patriotism education in a multicultural nation are: to what extends can we allow minority groups to keep their own identities and loyalties to them, and is it legitimate to expect or enforce positive and affectionate attitudes towards the ‘national identity’ defined from the majority group’s perspective? I argue and suggest some guidelines for patriotism education in a multicultural nation: multiple identities and loyalties to them need to be allowed and encouraged; positive attitudes towards and love of one’s nation should not be based on or lead to negative denigration of other nation groups; the boundaries that distinguish ‘us’ and ‘them’ need to extend as far as possible so as to include all members together without any form of discriminations; the values that are taken to be proud of as the sources of national pride and patriotism need to be congruent with universal democratic values such as human rights, freedom, and justice, if uncritical patriotism is to be avoided.
