On the way from the Renaissance to our days we have enriched our experience, but we have lost the concept of a Supreme Complete Entity which used to restrain our passions and our irresponsibility. We have placed too much hope in political and social reforms, only to find out that we were being deprived of our most precious possession: our spiritual life. In the East, it is destroyed by the dealings and machinations of the ruling party. In the West, commercial interests tend to suffocate it. This is the real crisis. The split in the world is less terrible than the similarity of the disease plaguing its main sections.
