You can answer my question for starters, does the pocket contain itself? does the universe contain itself?

I think that indeed it does.
U \subset U \subset U\subset \ldots ad infinitum, so nothing cannot really exist.

Does the pocket contain itself? :-)

There is always something... That's the magic of existence.

:-) I guess this is why you are called:"TheMadFool"...

There are no saints.
people will rape and kill if they weren't afraid of what would happen after they have done those deeds.

How did Michael Jackson say it :"tell them it's human nature".

Are we animals?
I guess so.

You can make the claim that the complicated and complex is made of easy and simple to comprehend ideas which as a whole make the complex and complicated easy to comprehend.

In that case it's like a point in geometry which is zero dimensional but the the whole line which is made of infinite number of these points is one dimensional...

I feel like I have already discussed this before... :-) Dejavu.

I am not sure that a university is not a bathhouse...
Anyway the context is the excerpt of tim wood's first post.
Obviously every x is different from y, but x has properties or qualities similar to y.
:-)
Anyway if something is too easy you lose interest in it, this is why life is so hard.
This is the case also in mathematics, if a problem you pose is too easy people won't be interested of course there's the saying of Feynman:
" According to the Nobel Prize-winning physicist Richard Feynman (Feynman 1997), mathematicians designate any theorem as "trivial" once a proof has been obtained--no matter how difficult the theorem was to prove in the first place. There are therefore exactly two types of true mathematical propositions: trivial ones, and those which have not yet been proven."

So perhaps all of math is uninteresting and boring, though I would like to think that the fact that there are difficult proofs is to the contrary to Feynman's anecdotal quote.

Well if you believe that "death comes to us all" you can't argue against the pessimist that argues that something bad is going to happen.
If you believe in an afterlife or some sort of defying death all the time then you are bound to be an optimist.

But it seems optimists do die, unless I am solipsistic and I am the only mind in existence; quite hard to believe in such an option.
