I don't like this argument. Well, its really just a statement I guess. What makes you know beyond any doubt that we will never live in a world without violence? Just because it seems like we never have, doesnt mean we never will. Thats merely an opinion, albeit a common one, but to me it has not been proven that we cannot create a world without violence. I actually think it is inevetible as we learn from our mistakes and evolve over time. Why is it not possible? One of the first hurtles to overcome is this idea that it is impossible!
