There are two Americas. One is the America of Lincoln and Adlai Stevenson; the other is the America of Teddy Roosevelt and the modern superpatriots. One is generous and humane, the other narrowly egotistical; one is self-critical, the other self-righteous; one is sensible, the other romantic; one is good-humored, the other solemn; one is inquiring, the other pontificating; one is moderate, the other filled with passionate intensity; one is judicious and the other arrogant in the use of great power.

It is not our affluence, or our plumbing, or our clogged freeways that grip the imagination of others. Rather, it is the values upon which our system is built. These values imply our adherence not only to liberty and individual freedom, but also to international peace, law and order, and constructive social purpose. When we depart from these values, we do so at our peril.
