Abstract This paper addresses the political ideal of democracy proposed by John Rawls in his book Political Liberalism (1995) and from which standards on what constitutes the public concept of citizenship of such ideal are based. This assumption requires an understanding of how we should conduct ourselves as democratic citizens, which inevitably involves individuals’ awareness on the ideal of public reasoning. The ultimate goal will be to understand that the concept of citizenship according to Rawls reaches all its political dimension to the extent that it contains and expresses the public arena as the key element.
