There is an authentic biology of hope. Belief and expectation - the key elements of hope - can block pain by releasing the brain's endorphins and enkephalins, mimicking the effects of morphine.

Hope gives us the courage to confront our circumstances and the capacity to surmount them.

Hope, true hope, has proved as important as any medication I might prescribe or any procedure I might perform.

True hope is cleareyed. It sees all the difficulties that exist and all the potential for failure, but through that carves a realistic path to a better future.

Hope is the elevating feeling we experience when we see - in the mind's eye - a path to a better future.

To hope under the most extreme circumstances is an act of defiance that permits a person to live his life on his own terms. It is part of the human spirit to endure and give a miracle a chance to happen.

Help, then, is the ballast that keeps us steady, that recognizes where along the path are the dangers and pitfalls that can throw us off; hope tempers fear so we can recognize dangers and then bypass or endure them.
