“...international solidarity can take new and more constructive forms as the great majority of the people of the world come to understand that their interests are pretty much the same and can be advanced by working together. There is no more reason now than there has ever been to believe that we are constrained by mysterious and unknown social laws, not simply decisions made within institutions that are subject to human will -- human institutions, that have to face the test of legitimacy and, if they do not meet it, can be replaced by others that are more free and more just, as often in the past.”
