Please analyze the theme of the work Death Be Not Proud by John Gunther.

From the most fundamental of themes, the book takes the
Donne poem and applies it to the situation of Gunther's son's death.  In praising the
condition of the human spirit, Gunther is able to display the fortitude of courage when
facing the ultimate adversary.  He creates a memoir that acknowledges the power of
death, but refuses to acquiesce to the force of negation.  Rather, Gunther brings his
son alive to us, the reader, in the face of death.  In its presence, we understand how
special his son was to both father and to the world.  Death is not presented as a force
that takes away his son's life, but rather one that causes celebration of this brief
zeal that was associated with Johnny.  In recognizing his son in this manner, Gunther
feels that he is able to take one of the saddest images known to humanity and
appropriate it in the name of his son and as a representation of a parent's love.  The
primary theme in this process is not to mourn the loss of life and love in the face of
death, but rather treasure what is present in our own lives so that when it is taken
away, no regrets will be felt nor despair experienced.
