The world we are living in now is a world of difference. There are differences of culture, religion, political creed, morality and ways of life. It is also a world of conflicts.
People fight because of the above.
Liberal thinkers claim that liberal toleration is the most desirable solution for conflict. Francis Fukuyama claims that the end of the Cold War equals the end of the history and the outcome is the final victory of the Western idea of liberal democracy. Samuel Huntington, on the other hand, opposes the idea of the end of history, saying that it is not the end but the start of conflicts mainly stemming from the clash of civilisation. John Gray rejects both theories. He claims that it is a utopian illusion to believe that the world will converge to a single ideology.
