David,
Can somebody forward this on to Mike Daly, whose email I can NEVER recover? I was taught this fascinating trope in graduate school... yes, THAT long ago. There is a second shoe, however. Yes the retina (cochlea, etc.) is that sensitive BUT the neural noise is much louder than that. So ... I think this is the right language ... even though the elements are sensitive to the smallest stimuli possible, the whole system cannot resolve stimuli that small ... anywhere near. To do what it does, it needs to weed out its own noise. So accuracy in vision is not a question of accuracy of the elements, but of the ingenuity of construction. Note, for instance that we wear our retinas "backwards": we actually see THOUGH the many layers of the retina because the light sensitive elements ... the rods and cones ... are at the back of the retina. So all that sensitivity of light sensing elements is rudely cast away in the organization of the retina. It's like we are a football players who wear our jerseys inside out but boast about the precision, detail, and color of our logos. Hope you are well. Where are you well? All my Peirce books were lost in the mail coming here, so I have been focusing on my garden. Mild, calm June. May be the best garden ever. But my mind? Not so sure about that. Nick Nicholas S.

David,
I will see your "bushwash" and raise you a hornswaggle. Why, my feathered friend, if quantum accuracy is so important, do you wear your retina backwards? Why do you see through your ganglion cells.

Ah Nick,
because they finely tune the carrier wave (that which you perceive as neural noise) in such a way that my quantum signal, being the delicate creature it is, can survive multiple synaptic shocks as it moves from neuron to neuron — the way you would want a well padded barrel when going over Niagara Falls. davew (I assume you are wearing your hip boots as standard gear in the MIB.)

Deep philosophical question: I don't think the nervous system is interested in accuracy, per se. It is interested in prediction. So, an "inaccurate" system that give a better prediction of future events would be favored overran accurate one. The deep question, which I suspect you Wise Guys are in a position to answer for me is: to what degree is predictive accuracy dependent on accuracy of input. Now the first intuition is "entirely." In meteorology, they talk about the "initiation of models", which I take to mean how good were the measurements that they plugged in for today's observations on which they based their predictions of future ones. I wonder what sort of tradesoff exist between getting the original points right and getting the model right.
But I note, even as I drown here, how come we wear our retina's backwards. Seems awfully careless of us, doesn't it?

In reply to this post by Nick Thompson
re: "deep philosophical questions:
Two (at least) quite different answers depending on the philosophical school answering. One, the Rationalists among us will agree with your "entirely" comment. Precision is required for both the model and the inputs — subject of course to the odd butterfly or two. Process philosophers (e.g. Whitehead, Heidegger, Korzibski, Heraclitus, some Postmodernists, Alan Watts and most Buddhists) would assume inaccuracy in both model and input. A 'process' is highly dynamic and constantly changing, at least in 'detail'. What appears to be 'consistency' and 'predictability' is more akin to a kind of momentum. I have to take a ferry each morning and evening across the IJ river and the process of steering a multi-ton, 35-meter, ferry to align with a 5-meter opening at the dock on each side requires constant imperfect measurements of dynamic forces of varying degrees - river current, wakes from passing ships, wind, etc. - and imperfect or 'gross' adjustments via engines and rudder is a process. There is not model, except a transient and constantly changing one in the captain's head and measurements / adjustments arise from another process - constant adjustment of heuristic observations synthesized (overlay fashion) with memories. The assumption for a process philosopher is that the world provides nothing but messy inputs to the ability to deal with them would be the advantage. To bring the sensitivity question back into play: the real messiness of the external world arises from the quantum level - the fundamental 'process' occurs within (below, underneath, at different level) the apparent stability and predictability of the Newtonian world. The latter is illusion and attempts to conform to it lead to silliness like wearing retinas backwards, attachment, karma, rebirth, politics, etc. etc. Luckily we have sensitivity to the quantum and therefore have the potential for enlightenment.

Dave West Wrot: To bring the sensitivity question back into play: the real messiness of the external world arises from the quantum level - the fundamental 'process' occurs within (below, underneath, at different level) the apparent stability and predictability of the Newtonian world. The latter is illusion and attempts to conform to it lead to silliness like wearing retinas backwards, attachment, karma, rebirth, politics, etc. etc. Luckily we have sensitivity to the quantum and therefore have the potential for enlightenment. The Monist replyeth, I care not for your quantum or Newtonian world. All I care for is experience. I care not at all if it is experience OF anything, except insofar as such constructions help me to regulate my experience. But the Monist still wonders why the design of my retina does not introduce unnecessary turbulence in the prediction and control of my experience. Why go to all the trouble to have a quantum-sensitive system, and then throw it away by the design of the retina? Nick Nicholas S.

Nick, I think I remember, from my time as a psych student, an experiment in which the reversal of the retina was undone by special lenses and the subjects adapted perfectly surprisingly quickly.
