In Iain M. Banks's newest novel of Science Fiction, The Algebraist, the main character, on two different occasions is afflicted with a peculiar psychological problem.

In order to explain this phenomenon I shall have to explain the setting. The story takes place in the forty-first century or so and humanity, with the 'help' of the over-arching galactic hegemony, the Mercatoria, has become a part of that expansion. Humans have spread across the cosmos and in some minor ways have become important for a number of seemingly minor functions. The main character in this book is something of a backwards ethnologist; he and a number of families of humans are the Seers, the few who are allowed to commune personally with the one of the galaxy's oldest and most widespread civilizations. These Seers have been deigned entry into the most poorly organized libraries in the galaxy, picking through to try to find small kernels of knowledge which they can turn into serious cultural enhancements.

So thousands of years in the future, slices of humanity are embroiled deeply in galactic politics. Vast armies of alien species clash and many humans fight along side them. And at the center of it all, every now and again, especially when drunk, humans will experience the feeling they've dubbed "Swim." It's a sort of nostalgia mixed with not a small amount of horror and paranoia. A feeling of detachment and homelessness. A sort of vertigo developed from being many hundreds or thousands of light-years away from what nearly every generation of your ancestors thought of as 'the ground.'

It begins with the wandering of thoughts, late at night, or what passes for it, staring up at the stars, drinking. It can be triggered by any number of things: imported genuine French wines, a glance over a star map that alights upon Sol, a post-card on a book-shelf from some great aunt's pilgrimage/vacation. The mind slips quietly toward whatever connections exist between you and that blue-green sphere in that, oh so, unfashionable spiral arm of the galaxy. And you let yourself think, "What. Am. I. DOING HERE?!" Here amongst a million different alien species, in a gigantic galactic government where every few million years the entire system is thrown into chaos and misery by vast, ancient and powerful civilizations. Here I am, a poor, pink, squishy, vulnerable human amongst a myriad alien monsters, thousands of light-years away from Home. And it all comes crashing down on you at once: all the struggles and tiresome burdens that humanity must carry, all of mind-crushing bigness of the galaxy, all of it focuses in on how small and pathetic and short lived humans are and all of it is crashing down on your ears. You look at the universe and see how futile trying to succeed as a species when nearly every other species can expect perhaps ten or a hundred thousand years before they're completely wiped out by this galactic war or that genocidal group of aliens convinced that humanity is going to start the next galactic war.

It all happens in a split second and you shake your head, probably fuzzy with alcohol. And if you are among friends you can admit to them that you just got "Swim" and you'll feel their sympathy. You'll sleep and the next day you wake up and breath in the air on a world or ship that has not seen light produced by human means and look up at a sky that's the wrong color of blue with a sun whose light is just a shade on the bluer or redder side.
