I could never write about strange kingdoms. I could never do 'Harry Potter' or anything like that. Even when I did science-fiction, I didn't write about foreign planets and distant futures. I certainly never did fantasies about trolls living under bridges.
I would like to see us get this place right first before we have the arrogance to put significantly flawed civilizations out onto other planets, even though they may be utterly uninhabited.
Man is a microcosm, or a little world, because he is an extract from all the stars and planets of the whole firmament, from the earth and the elements; and so he is their quintessence.
Accordingly, since nothing prevents the earth from moving, I suggest that we should now consider also whether several motions suit it, so that it can be regarded as one of the planets. For, it is not the center of all the revolutions.
Planets are too dim to be detected with existing equipment, far away, except in these very special circumstances where they're seen by their gravitational effect.
The motions of the comets are exceedingly regular, and they observe the same laws as the motions of the planets, but they differ from the motions of vortices in every particular and are often contrary to them.
I believe that these extra-terrestrial vehicles and their crews are visiting this planet from other planets. Most astronauts were reluctant to discuss UFOs.
The planets are never the same twice, they're always different, so they could compare the markings I had drawn with their current photographs and they knew that I was drawing what I was really seeing and it wasn't copied from somewhere.
