Yes, ideas shape the world!
How to understand the world? To understand the world, you have to have a philosophy! No philosophy, no world! Yes, as simple as that! But it took 2,000 or more years to reach that conclusion!
How to judge the present situation of the world? Optimistic? Or, pessimistic? What hopes for a more tolerant world, more enlightened and less repressive regimes across the nations and continents? There are tensions in large parts of the world. The Iraq war, the Israeli war-like events, the daily reports of deaths reported from the wars and terrorist attacks can’t make any sensitive person but get disturbed. These are the thoughts and occasions when you turn to some more fundamental quest. That is where philosophy comes in.
