So, what is peace? My simple answer is that peace is much more than the absence of war or violence. For someone, peace can be a walk in nature, and for another, a romantic dinner with your spouse, playing with children, doing yoga, or traveling to a new country and experiencing the local culture. There are as many peaces as there are people in the world.
My technical answer is that peace can be seen as the substance of any positive impact. This is enabled by the plurality and transrational nature of peace that transcends duality. Based on a wealth of studies and treatises in world literature, peace is believed to offer a guiding principle for the betterment of any aspect of human activity.
And, finally, in my elaborate answer, I define 1+3 levels of peace. Nonwar is the absence of physical systematic violence and Weak Peace is the absence of structural or cultural violence. This includes violence against nature, such as pollution. Strong Peace is the first level of peace that describes substantial peace rather than the absence of negative traits (what it actually is and not only what it is not), and it is the presence of any positive values, ideals, or virtues desired by society, such as justice, health, wealth, education, or sustainability. And finally, Holistic Peace is a transrational, spiritual vision for humanity, an ultimate higher purpose of human endeavor, and moral excellence. (These are inspired by the works of Johan Galtung and Wolfgang Dietrich.)
My concluding answer is that peace serves as an ultimate visionary yet reachable goal. Accordingly, peace is an amalgamation of those ideals that the thinkers of the world have identified as necessary, right, and beneficial for the advancement of human potential. It needs to be noted that each of the above-mentioned levels of peace has both an inner and an outer dimension. In other words, there can be an absence or presence of negative or positive states within one’s mind and/or within or between individuals, groups, organizations, societies, or nations. Yet, holistic peace can likely be achieved only through the extension of inner peace to outer peace.
