As loyal critics of the university whose worldviews furthered key existentialist commitments, Octavio Paz and Hazel Barnes advanced philosophies of education inspired by the struggles of the 1968 student social protest movements. Their appeals to what a complete university education is and ought be demonstrate remarkable compatibility given their existentialist affinities and so are relevant to a normative critique of the mission of today's colleges and universities. Both took seriously the idea that the university's didactic mission should include the ideal of cultivating a socially and politically desirable, and morally defensible, account of the individual self in action. These thinkers also contended that the university should be seen as a place where selves in action rehearse engaged moral reflection towards self-fulfillment and social justice across generations. Seen against the violence that marred such episodes as the police riots during the Democratic Convention in Chicago in August 1968 and the Tlatelolco Massacre in Mexico City weeks later, my argument demonstrates how and why the radical normative underpinning of Barnes' and Paz's philosophies of education offer important guidelines for appraising the purposive nature of today's university. One key outcome of my paper is that it points the way towards what I will call a pan-American existentialist philosophy of education that is responsive to the generational needs, ideals, and challenges of students today across the universities, communities, and nations of the western hemisphere, especially between the United States and Mexico.
