Worlds of Difference engages the social constellations of education and what it means to actualize a public sphere for pedagogy that depends on the political conditions of an incessant globalization of cultures. Its chapters aim to elucidate the philosophical and ethical implications of arguments that slide across the continua of theoretical and political thought from the neo-liberal right to the democratic left. Questions of citizenship and democracy always arise in relation to problems of achieving “unity in diversity” and what that means for principles of equity, sovereignty, and the right of subjective agency. Each contribution to this collection leads us into the complex pathways of these burning issues and navigates a way for us to think about them as sites of praxis through which faith and hope in the power of subjective agency can be restored. The collection looks forward to the possibility of enacting new horizons of theory and practice for social reconstruction via the forum of an open, inclusive, and public discourse on the ethics of education in the twenty-first century. Only by opening up the contested spaces of meaningmaking within the public sphere of education can we begin on the quest for social justice with a responsibility to a future yet to come, with a vision of individual and communal empowerment through education, and a pedagogy of critical democratic praxis amid worlds of difference.
