My favorite excerpt:
Human speech creates and destroys. With words we can paint unframed pictures that are only limited by the extent of our imagination. With words we create realities of emotion. Words generate love, fear, hatred and courage. Where desire does not exist words can often generate it.
Ambition and determination, success and failure, reputation and its undoing are all the products of words. With words we wound and with words we heal. War and peace can rise and fall on the power of words.
