"… ninety-one membranes are more effective in stopping photons than ninety, ninety are more effective than eighty-nine, and so on back to one membrane, which is more effective than zero. This is the kind of thing I mean when I say that there is a smooth gradient up Mount Improbable. We would be dealing with an abrupt precipice if, say, any number of membranes above forty-five was very effective while any number below forty-five was totally ineffective. Neither common sense nor the evidence leads us to support any such discontinuity".
Yet a child can see the fallacy of this reasoning! Any number of pigment layers are useless without the connecting nerve ‘wire’ to carry current to the brain, which are ***bundled together*** in human eyes to form the optic nerve, and without a part of the brain to process such information. It is only the combination of all components which makes ‘sense’ of the integral whole—the entire machine.
