I think you’re on the wrong side of the question now. Of course it is detatched from reality: it is only representing it. But what is a representation, then, if all we have are representations? In what sense could something not represent?
I should like to say: something can fail to represent only inasmuch as something can perfectly represent. And what is a perfect representation? —not a measure of certainty per se, but an element of knowledge.
But in what sense does a perfect representation really represent anything? Do we instead only have a representation of a perfect representation? When is a concept ever clear?
We took a measurement tack before, so let’s stick with that. We can say that an inch, meter, or rod is an arbitrary form of measurement. Which unit we choose is more or less only a matter of practicality. But saying an object is an inch long, is this still arbitrary?
I have no familiarity with the Celcius scale of temperature measurement, for example. You tell me it is 24 Celcius degrees outside. That sentence represents, to me, a phrasing of Farenhieght measurement which I do not understand. If the thermometer reads 75 then it is 75, not 24. And it isn’t seeming to be 75, I am not “reading it as” 75. Point of fact, though my system is arbitrary, it is necessary. If you remove the Farenhieght scale I have to relearn temperature.
But now: was it ever in question that there was a temperature to measure? Why is the scale the representation? Shouldn’t, in fact, even “temperature” be a representation? If you say “yes”, then don’t you have to answer: “…of what?” Because that’s the core question. I know something epistemologically… is this knowledge a representation of the thing known? Then what is a representation itself that I may contrast it with things that are not representations?
If everything is a representation, then there is nothing to represent, there is no thing that is represented. That being the case, there can be no empirical standard for assigning truth and falsity to a proposition, there is only what is done, and even that can’t be stated.
The null-epistemology.
