The great danger of living in a sustained period of peace is that it creates a mental fog. One begins to operate within an artificial world.
Typically, a period of sustained peace is relative to one’s geography. It becomes difficult to comprehend the act of surviving amidst life and death dangers. Most of history’s titans fought not just from an intellectual plain but also on a physical plain. Their very lives were often at stake. This is true of heroes from Washington to Gandhi.
I must be wary that sustained peace does not create lethargy.
