Is it possible to attain world peace while Christianity, Islam, Hinduism, Judaism and so forth exist side-by-side.
My idea of world peace is such that there is a global feeling of oneness, of connectedness. That none think higher of him/herself then of others. That every person has deep awe, respect and reverence for nature as a whole. If these things be found in reality it would automatically follow that mankind would give it her best to please every single person. To fulfill that desire at that moment only technical know-how and enough raw materials are needed.
World peace viewed in this sense, according to me, can never co-exist with the belief systems named above. I believe this because there'll always be a feeling of 'us and them' in a world where at least two different sets of belief systems reign.
I do agree that world peace shouldn't necessarily be viewed this way, if I alter my view of world peace in a view that focuses solely on the situational condition of man (does he have food, water, shelter, does he live in a safe and stable environment) and not as well on his sensation or experience of the world (his philosophical attitude to the world), then it is theoretically possible to attain world peace without a unification of religion and belief systems.
