This is very encouraging science for those of us not 20 years old.

But this was true with the old sciences as well.

For them, the old sciences were better left in peace.

While optics is an old science, new things are still being discovered in it.

Forgotten were the old sciences and their purpose in the world of man.

You see where we are headed, thanks to monstrous old science?

"Do your people know much of the old science?"

I chose the old sciences to learn, to recover in small part.

It only spread the disease of the old science to new worlds.

I didn't learn too much of the old science, but I know enough not to believe in such things.
