The introjection of symboling into primate social life was revolutionary. Everything was transformed, everything acquired new meaning; the symbol added a new dimension to primate—now human—existence. An ax was no longer merely a tool with which to chop; it could become a symbol of authority. Mating became marriage, and all social relationships between parents and children and brothers and sisters became moral obligations, duties, rights, and privileges. The world of nature, from the stones beside the path to the stars in their courses, became alive and conscious spirits. “And all that I beheld respired with inward meaning” (Wordsworth). The anthropoid had at last become a man.

Don't you understand? I got even this story from Ender's mind. It's his. And he got the seed of it from somebody else, something he read, and combined it with things he thought of until it made sense to him. It's all there in his head. While we are like you. We have a clear view of the world. I have no trouble finding my way through your mind. Everything orderly and sensible and clear. You'd be as much at ease in mine. What's in your head is reality, more or less, as best you understand it. But in Ender's mind, madness. Thousands of competing contradictory impossible visions that make no sense at all because they can't all fit together but they do fit together, he makes them fit together, this way today, that way tomorrow, as they're needed. As if he can make a new idea-machine inside his head for every new problem he faces. As if he conceives of a new universe to live in, every hour a new one, often hopelessly wrong and he ends up making mistakes and bad judgements, but sometimes so perfectly right that it opens things up like a miracle and I look through his eyes and see the world his new way and it changes everything. Madness, and illumination. We knew everything there was to know before we met these humans, before we built our connection with Ender's mind. Now we discover there are so many ways of knowing the same things that we'll never find them all.

In the end, humanity is nothing more than a meat sandwich between heaven and Earth.
