"For all our Utopian foreign policy, we have neither the wealth nor the domestic political unity of Utopia. We badly need a theoretical chastisement, after almost two decades of war, because the practical chastisement of elections (or the national trauma of Vietnam) has not taught us to be mindful of our own weaknesses. Instead, we presume invincibility, or at least invulnerability, and adventure across the globe. Even if we cannot see ourselves through our enemies’ eyes, for we concede them no worth or even serious acknowledgement of their existence—we must at least see ourselves through the eyes of friendly critics. Let’s learn from More and prepare for the possibility that progress toward Utopia is limited, for if the tragic world returns, where war ruins even prosperous and decent peoples, great prudence will be called for in the future."
