Plague has hung over human history. The biggest human extinction was after 1492 in North and South America when the mortality rate was 95 per cent, which is enormous. But again, I'm actually giving you grounds for optimism: There were enough to continue. The five per cent who made it through are what you need to survive a bottleneck, which we have been through before.

Potential has a shelf life.

If we read books all the time we would be very unhealthy, as we would not get any fresh air, exercise, or contact with nature. Also we would not spend time with other people. There are a lot of plusses to reading - it's an interactive brain workout - but like everything else that's beneficial in moderation, overdoses can be dangerous.

By telling you anything at all I'm at least believing in you, believe you're there, I believe you into being. Because I'm telling you this story I will your existence. I tell, therefore you are. So I will go on. So I will myself to go on.

Even an obvious fabrication is some comfort when you have few others.

If I pick up a book with vampires on the cover, I want there to be vampires. If I pick up a book with spaceships on the cover, I want spaceships. If I see one with dragons, I want there to be dragons inside the book. Proper labeling. Ethical labeling.

What a lost person needs is a map of the territory, with his own position marked on it so he can see where he is in relation to everything else. Literature is not only a mirror; it is also a map, a geography of the mind. Our literature is one such map, if we can learn to read it as our literature, as the product of who and where we have been. We need such a map desperately, we need to know about here, because here is where we live. For the members of a country or a culture, shared knowledge of their place, their here, is not a luxury but a necessity. Without that knowledge we will not survive.
