Is the concept of heroism in Western culture under attack?

As the Chief of Awards and Decorations for the 9th Infantry Division in Vietnam I had plenty of occasions to think about the nature of heroism, especially when I investigated and reported on acts of valor rising to consideration for the Medal of Honor. In later years I taught my son and his fellow Cub Scouts that valor was to do whatever was necessary or right in spite of fear. Thus, without fear there could be no heroism (at least that was my opinion). All soldiers are frequently called upon to do their duty regardless of the fear they felt. However, some act above and beyond the call of duty. These are the ones we most often equate with heroism.

Obviously, others have different interpretations. Also, the definition of heroism has evolved over the centuries. It can mean many things in different places and different times. Modern Americans apply the term loosely to athletes and celebrities whose only fear was failure, and the "hero" has lost its traditional significance.

Tod Linberg, PhD and Fellow at Stanford Univesity's Hoover Institution, has gone so far as to postulate that heroism itself is being diluted and that its loss imperils society. What do you think?
