The purpose of Utopia

In episode 5 oh the NJAG Podcast Brody speaks about the power optimism and cites this beautiful poem by Eduardo Galeano:

“Utopia lies at the horizon. When I draw nearer by two steps, it retreats two steps. If I proceed ten steps forward, it swiftly slips ten steps ahead. No matter how far I go, I can never reach it. What, then, is the purpose of utopia? It is to cause us to advance.”
