They are opened-eyed dreams. Within these dreams many people operate under the belief in personal objectivity. Some of them will then try to dazzle us with facts proving this belief. Acknowledging our subjectivity doesn't mean being unfair, and it isn't an excuse for a lack of clear judgement. It just means not claiming an absoluteness of viewpoint we really don't possess.
Objectivity is the result of beliefs that are mistaken for reality.
The great mistake of believing in the illusion of personal objectivity has made people blind to the reality experienced by others with differing beliefs. At times I have noticed that many of those operating under the illusion of objectivity think they are surrounded by stupidity. These standards while having many similarities will also have many differences. From these differences conflict will emerge in their viewpoints. When their worlds meet, their contrasting ideas will do battle in the physical world.
