Hello friend,

I agree whole-heartedly with your idea that maybe we are both
ascending one hill and descending another at the same time.
Maybe it’s a cheerful nihilism, and I know I’m an idealist and maybe
someday I’ll crash, but I think all of this figuring out has to
happen in its two simplest parts simultaneously - the speculating
and the doing. You need to do the lab with the scratchwork, and I
like that perhaps these two parts have to face in two different directions,
as you would say. The idea of an ’answer’ doesn’t satisfy me really,
because answers aren’t real. Sure, they’re practical, but they’re
not It. In all of these absurd gestures, I’m trying to make
something else matter. What I like about thinking of my hypothetical
urban wind trajectories, for example, is that the maps ignore an
order of importance. Yeah, there are a million variables that
effect the wind, but what happens if I arbitrarily isolate a
couple and grant someone’s whisper the same power as a building’s
demolition? Rather than directly disempowering dominant
things, I like giving a voice to small, seemingly negligible
things. It’s my small way of kicking down hierarchy. So
here we are at the other end of the spectrum, not keying in
on one variable at a time but trying to effectively include
Everything. Yikes. To assume a definitive answer to this
is to assume quite a command of Reality - whatever that is!
Perhaps the project started as a response to a certain
discontentment with assumed reality, assumed limitations,
assumed boundaries and separateness, and a desire to enter an occult
alternative into the realm of the reasonable. While stubborn and absurd,
I do consider myself a practical girl, a poetical pragmatist, if you
will. But, oh dear, the closer I get to Reality, the further I am from
being sure of anything at all. Now the project is a playful crisis, really.
So, we ask, why bother? But what else are we to do - wait around for a
more agreeable reality?

’We have no idea how long we’d have to continue until we have a chance
of even knowing what our chances are.’ Yep, that sounds about right.
Except, I want to make clear that there exists a chance. It’s
important to me that I believe in these things.

yours,
Liz
