I think there is a great danger in living in a sustained period of peace. 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 on a physical plain. There were times when their very lives were at stake. This is true of heroes from Washington to Gandhi.
I must beware that sustained peace does not create lethargy.
