In my outline of book ideas posted recently (see previous posting) specifically in the brief outline of 'Mobile Home,' I mentioned a character called Trevor: "a being who can perceive only two dimensions and lives on a shovel." This rather brief description may have confused or hopefully intrigued you; it may even have amused you; but I feel that Trevor needs a little more introduction if you're to appreciate what a remarkable lifeform he really is, (and why the surface of a shovel could possibly be an adequate domicile for him.)
I've dug out an introduction to Trevor that I wrote years ago, even before the ideas for 'Mobile Home' occurred to me, but while I was pottering around with the concept of writing about a species that was only aware of two dimensions, just as we're only aware of three (or possibly four, if you're a physicist of that particular persuasion.)
It's rather short and also incomplete. It's in exactly the same form as I wrote it about three years ago, so it could probably benefit from some editing, but I've presented it here unchanged. Reading it recently, I was even mildly amused myself, so I hope it manages to at least raise a smile with you too.
Trevor and Nigel lived in a multi-dimensional universe: a fact that they were only partly aware of; that was to say that they had a bit of a blind spot when it came to the 'multi' bit of the 'multi-dimensional' idea, in that the number of dimensions they were conscious of was only two.
It wasn't that they were stupid: On the contrary, they were two of the more intelligent members of their species; but their species consisted of beings whose bodies were only a few cells deep. They had all of the usual sensory organs, but each of their senses was only receptive on a single plane. They had no problem with left or right, and forwards and backwards held no mysteries for them either. Up and down on the other hand, meant absolutely nothing to them. They were 'surface dwellers' in the
absolute sense of the term.
In spite of their apparent limitations in perception, the species had developed into the most intelligent on their planet. OK, so they were the
only sentient species on their planet, but nevertheless the extent to which their intellects had advanced beyond that of the moss, grasses and assorted microbes who shared their world was incredible. Trevor was one of a number of profound thinkers among his people (if 'profound' is a word to use for someone who's unaware of the concept of depth,) and he would have been amazed at just how far above the lesser species his people had evolved. At least he would have, had he known what 'above' meant. To be honest, he may have had a bit of a problem grasping the concept of 'evolved' as well; when your species is the only one around, developing a theory to explain how you came to be, is not really on the to-do list of even the most philosophical of individuals.
There was however, limitless scope for philosophy in Trevor's world. Existing in a two-dimensional world left many questions unanswered; questions whose solutions would have been obvious in a world of three (or even more) dimensions.
Trevor mentally studied his list of questions. Leftmost in his list (since lists had to be written sideways for obvious reasons, and starting at the left seemed as adequate as the alternative) was the question of the light. There were periods of dark followed by periods of light; they varied in duration, but one thing he'd always noticed was that when the light-time began, things were always illuminated to one side of him first; always the same side as well, unless he was facing the other way; and when the dark-time was beginning, the last things to stop being visible were always at the opposite side.
"It's as if the light is a sort of force passing through our world in waves, always in the same direction, flowing around us as it goes," he said to Nigel. This was of course, though totally inaccurate, an interesting theory for someone with a 2-D outlook. The fact that he was able to share his thoughts with his companion was no less interesting: A body that's only a few cells deep doesn't leave much scope for a decent set of vocal chords. Trevor didn't need vocal chords: like all of his species, he'd evolved to communicate via a sort of thought transference. He 'spoke' to Nigel by sending concepts and ideas, not words; they didn't use words at all, in fact Trevor and Nigel weren't even their real names, but since we can't communicate by sending concepts and ideas, we have to call them something.
'Light' and 'dark' were two concepts that they understood; they were things that happened, even if they couldn't get their thoughts around the mechanism as to why they happened. 'Wet' and 'dry' were another two that were easy to grasp: Trevor and Nigel could sense moisture as well as light and there were times when they sensed that it was wet and times when it was dry; these times weren't as regular as the periods of light and dark, and it had been known to be wet in one place at the same time as it was dry in another. Some places that they knew of were always wet and never dry.
"If it's a force like the current and it's flowing like we know the current does," said Nigel, continuing the discussion about the light, "why doesn't it affect us like the current does?"
"It's a different force, so it'd probably have a different effect," answered Trevor, "The light flows
around us and it's everywhere; the current pushes
against us and is only present in some places."
The 'current' was how Trevor's people chose to explain the curious one-way discrepancies between 'fast' and 'slow', which were two other facts of life in a 2-D world. Just like there were times of light & dark and times & places of wet & dry, there were also places where moving took a lot less effort than others and these were the fast and the slow; the fact that the fast places were covered with moss and the surface of the slow places was coarse sand was a connection that had never presented itself.
For some reason some areas took less effort to move in one direction than in the other; in a 3-D world these areas would have been called 'slopes' or possibly 'inclines', but in two dimensions this phenomenon was explained as an effect called 'current.' Under the influence of the current, both the fast and the slow got faster in one direction but slower in the other.
As ever, remarks, comments and criticisms are welcome and invited. Your feedback is important to me.
Thanks.
