Greetings.
So you have read some of the most interesting Lem-Books.
The giant-ant colonies.
They had been a great miracle for me, but there are two theories, which I have got.
1. This should be a indirect way to proclaim the inhabitans of the quinta.
Lem won't explain them directly, and so he choose the indirect way. That's a way of psycho-analysis and could be wrong, naturally.
But I think Lem's thought was (please don't damn me, for saying I know what he think.
I don't, but I try to construct )
"I can't describe an Alien, because if there will be a contact, my describe is surely wrong.
So I am not allowed to describe, if I won't fail."
These Story is maybe a symbol for the search for contact with extraterrestrial intelligence.
In the End, it fails, after all difficulties the box is empty.
A little bit negative, but perhaps right.
