Faiths

Man will stand up to defend what he believes in. Religion, ideology, belief, faith - call it what you may. Early man was geographically spread across vast areas of land, separated by natural boundaries like mountains and oceans. The birth of ideologies in these distinct populations was naturally peaceful as all people of one geographical area subscribed to one thought, and there was no reason for conflict. With an increase in population, the urge to explore, conquer and rule swelled. This led to the clash of armies first and religions later on. The former was swift and brutal, but the latter wasn't. Because man will hold on to his faith and die rather than give in to an alien one. Because feelings like hunger and survival are physical, but religion and ideology stem from someplace more fundamental than the physical self.
