After reading the following message, you should have a basic understanding of civilization on Earth. By dint of long toil and creativity, the human race has built a splendid civilization, blossoming with a multitude of diverse cultures. We have also begun to understand the laws governing the natural world and the development of human societies. We cherish all that we have accomplished.

But our world is still flawed. Hate exists, as does prejudice and war. Because of conflicts between the forces of production and the relations of production, wealth distribution is extremely uneven, and large portions of humanity live in poverty and misery.
