We, who live in the present - day world, are proud to call ourselves civilized. It is because we live and dress better than our forefathers. Of course, we have the advantages of the inventions of modern science which our ancestors had never known. But let's search our hearts and ask ourselves, "Has science solved our problems?" Frankly speaking, the answer is, "No". In fact, science has added to our worries. Perhaps, now we can kill more easily and swiftly than ever before. And then, we have not given up the old habit of fighting. That is why we have wars after a decade or two. If we wish to be really civilized, let's learn to live in peace. Let's achieve brotherhood of man.
