"There also exists a constant tension between ideas and realities. Realities simply are, whereas ideas are worked out. There has to be continuous dialogue between the two, lest ideas become detached from realities. It is dangerous to dwell in the realm of words alone, of images and rhetoric. So a third principle comes into play: realities are greater than ideas. This calls for rejecting the various means of masking reality: angelic forms of purity, dictatorships of relativism, empty rhetoric, objectives more ideal than real, brands of ahistorical fundamentalism, ethical systems bereft of kindness, intellectual discourse bereft of wisdom."
