Ive just finished flipping through and re-read pages of 'Battles: the art and science of modern warfare' (edited by Lewis, J.E 1995). What I like most about the book is how it is introduced.
Lewis says, "If war is not an inevitable part of human nature, it is an enduring one."
Paused for while, I am quite certain that life is fairly an arena that is full of challenges. It is.
