“The power of language to color one's view of reality is profound. In many instances, the most significant factor determining how an object will be perceived is not the nature of the object itself, but the words employed to characterize it. Operating through the lenses of contrasting linguistic symbols, two persons looking at the same phenomenon are likely to come up with sharply divergent observations. Words can also act as a force for justice or a weapon of repression, an instrument of enlightenment or a source of darkness.”
