The number of ideologies, cultures and religious throughout the world is continually on the increase, and there seems little chance that this tendency will be reversed. One can no longer adopt an attitude of mere tolerance when faced with such multiplicity, as one could have done in the past when such civilizations, cultures and religious were closed-in systems, independent of one another. Co existence or more exactly merely peaceful relations between them. But such an attitude is becoming daily less feasible. Today we should rather talk of frankly accepting other systems as they are and of opening ourselves up to them under our true colors, in order to seek beyond our differences, the points on which we agree and which can lead us to a higher unity than that which binds us to the members of our own particular group.
