All this calls for a new approach to global problems. The world is becoming smaller and smaller – and more and more interdependent – as a result of rapid technological advances and international trade as well as increasing trans-national relations. We now depend very much on each other. In ancient times problems were mostly family-size, and they were naturally tackled at the family level, but the situation has changed. Today we are so interdependent, so closely interconnected with each other, that without a sense of universal responsibility, a feeling of universal brotherhood and sisterhood, and an understanding and belief that we really are part of one big human family, we cannot hope to overcome the dangers to our very existence – let alone bring about peace and happiness.

One nation's problems can no longer be satisfactorily solved by itself alone; too much depends on the interest, attitude, and cooperation of other nations. A universal humanitarian approach to world problems seems the only sound basis for world peace. What does this mean? We begin from the recognition mentioned previously that all beings cherish happiness and do not want suffering. It then becomes both morally wrong and pragmatically unwise to pursue only one's own happiness oblivious to the feelings and aspirations of all others who surround us as members of the same human family. The wiser course is to think of others also when pursuing our own happiness. This will lead to what I call 'wise self-interest', which hopefully will transform itself into 'compromised self-interest', or better still, 'mutual interest.'

Although the increasing interdependence among nations might be expected to generate more sympathetic cooperation, it is difficult to achieve a spirit of genuine cooperation as long as people remain indifferent to the feelings and happiness of others.
