If you think about some of the things that are being talked about by thoughtful, intelligent scientists, you realize that in 100 years the human race won't even be recognizable.

I don't think the human race will survive the next thousand years, unless we spread into space.

I am the entire human race compacted together. I have found that there is no ingredient of the race which I do not possess in either a small way or a large way.

Is the human race a universal constructor?

If much in the world were mystery the limits of that world were not, for it was without measure or bound and there were contained within it creatures more horrible yet and men of other colors and beings which no man has looked upon and yet not alien none of it more than were their own hearts alien in them, whatever wilderness contained there and whatever beasts.

Don't overestimate the decency of the human race.
