Cicero's quote speaks to the concept that peace is a state of being that is accomplished through the presence of liberty and serenity. In other words, peace is not simply the absence of dispute, but rather a state of harmony and balance that is developed when liberty and tranquillity exist. Liberty is the capability to choose and act freely without fear of injustice or persecution. Tranquillity is a state of calmness and tranquility, free from interruption or disruption. Together, these two elements develop a serene environment where people can live and flourish without fear or concern. Peace is not simply the lack of war, but rather a state of consistency and balance that is developed when liberty and tranquillity are present. It is a state of being that permits people to live and prosper without worry or concern.
