If you hold a piece of
wood in your hand, you might wonder if it is too short, too long, or just
right. It of course depends on what you want it for. Nothing can show its true
value until you relate it to something else. A point of view for example is
determined by what the observer is relating to. The nature, the value, or the quality
of something can only be measured in relation to another object. Having the
Hope Diamond in your hands is useless if you are stranded on a remote island
and are desperate for a drink of fresh water.
