Dear Marina,
I just read your essay and would like to provide my feedback.
First, the title: It strikes me as perhaps the most lyrical of all the entries, but that by itself is not a big deal; (most) anyone can come up with lyrical expressions of some sort or another. To make it lyrical and to have it precisely sum up the body of the essay is to me a form of art, and you did it.
Second, the body: The approach followed in your essay is consistent with the informal tone you set at the beginning. But informal does not mean that there are not some important insights to be shared. I gleaned three major ones:
1) "...each kind of creature perceives the world through its own set of narrow bands on various spectra of available information..." How true! I have sometimes tried to imagine what the world would be like if I could perceive it as some of the animals you mentioned (and others) do. Surely it would be very different. You can see just from astronomical pictures that the world looks quite different at different wavelengths. If the temperature of the sun were a just a bit different, we would have probably evolved sight within a visible spectrum that is different from our actual one. Perhaps, instead of using Magnesium to make chlorophyll, plants would have used iron to make hemoglobin-like compounds to perform photosynthesis (This is actually a research subject). Then plants would be red instead of green. I'm sure your friend wouldn't mind, though.
But seriously, the fact that this is so often forgotten is just another reflection of the the anthropocentric aspect that is imperceptibly interwoven in our worldview, which brings me to the second insight
2) "It [i.e. Wheeler's purported scheme whereby everything is reducible to the apparatus-elicited answer of a yes or no question] is limiting because it presupposes an a priori knowledge about both the universe at large and every specific thing in it..." I have now read many entries to this contest, and a fair number of them mentioned Wheeler's scheme, but none pointed out this implication, it did not even occur to me. But you are absolutely right, one can't ask yes or no questions about things about which one has no inkling and I agree that this is a serious limitation of his scheme. I think you have uncovered an anthropocentric facet that goes beyond the talk about measurement devices and questions because it makes plain that his scheme depends in an unmitigable manner on the observer's prior knowledge.
3) "From here it is natural to infer that it [i.e. participation] must also hold true for each and every thing in existence." I think this is a profound thought. Consider how many philosophers have tried to (unsuccessfully) define "existence". For example, if you look at the entry in the Stanford Encyclopedia of philosophy, you will find a lengthy article which fails to come to a conclusion. I have myself pondered the question for a long time (in fact, I have an essay in preparation which is tentatively titled "Quantum Mechanics and Existence"). If your approach works, then it can be used as a working definition for physical existence. The main question I would have is in what ways you would differentiate between 'participation' and a physical interaction. You have presented a cyclic schema, but it seems to me that one could label the steps also as components of interactions, though your discussion of the applicability of this schema in quantum mechanics suggests an approach for differentiating between them.
In any event, thinking of participation in this generalized sense seems to me immensely more sensible and fruitful than thinking of it in terms of the anthropic principle (you can probably tell that I am not a fan of it).
Here are some other short comments:
-the phrase "Grappling in the dark..." sounds vaguely familiar, where did I encounter this before?
-I also like the humor in your essay. I'm curious about the Russian expression, because I thought hamburgers were an American invention
-I think I got the general idea behind the fractal waves, but I think as you stated it, it may easily give one the impression that you are raising the possibility of superluminal signal transmission or information transfer. I would probably have been better to flesh out the idea some more. It may well be that there are locally causal chains of which we are not aware at a conscious level, but which we recognize subconsciously , and which would therefore, upon encounter with the effects of the first few members of the chain, trigger the kind of reaction that you mentioned.
I enjoyed your insightful and fun essay very much and wish you all the best,
Armin
