Mrtennis. I will use your proper name when you start using mine. Until then

let me try to escape from the paradox, byron, which you stated in a syloogism.
i make the assumption that only that which is either true or false is subject to proof.
statements of an analytic-apriori nature fall within the set of that which can be proven.
for example, in euclidian geometry, one can prove base angles of an isoceles triangle are equal. the proof does not involve the senses.
when you perceive, the result has some probability of being true and a probability of being false. thus perceptions cannot be proven true or false.
in the empirical world (experience) absolute proof is not possible.
in the world of the abstract, it is possible.
there are many other examples in trigonometry, boolean algebra, calculus, number theory, which are subject to proof.
None of this is under dispute. I completely agree that it is impossible to prove empirical statements with the same kind of certainty that mathematical and logical statements can be proved. That is a widely held view. In fact, it is the PREVAILING view among both contemporary philosophers and scientists. There is nothing iconoclastic in it, as you seem to believe.

the problem with perception is that one can never say the perception is true, with certainty.
one may have confidence in one's perceptions and act on them, but one can never be sure that one's perceptions are true.
confirmation by others, if the sample is large, can lead to confidence, but not truth.
Where to start? To begin with, it doesnt make one dent in the Paradox of Skepticism I presented to you in my earlier post. But lets ignore that for the moment.
The problem with perception, as you call it, is not nearly the problem you make it out to be. To begin with, science has innumerable examples of successfully explaining entities, properties, and laws of the physical universe that CANNOT BE PERCEIVED by the senses. You need look no further than
Wikis page on Elementary Particles to see a huge array of entities, properties, and laws that cannot be perceived (except very indirectly through instrumentation). That is an indisputable illustration that human knowledge has advanced far beyond the limits of human perception.
The fact that scientific theories are fallible, revisable, provisional in a word, uncertain, is not cause for Radical Skepticism of the kind you routinely endorse here on Audiogon. Science has generated the greatest succession of explanatory triumphs in recorded history, in spite of being uncertain. To deny the whole of science the status of knowledge on the basis of its uncertainty is like denying the polio vaccine the status of medical cure on the basis that it has only a 99% success rate.
By equating knowledge with certainty, you have created a concept of knowledge that is woefully out of touch with any ordinary, philosophical, or scientific understanding of what knowledge is, making your repeated statements about the limits of knowledge either incomprehensible or irrelevant. As for your comment that...
...confirmation by others, if the sample is large, can lead to confidence, but not truth...
...it is a mistake to conflate certainty with truth. Certainty is a characteristic of KNOWLEDGE, namely the absence of any possible doubt. Truth is a characteristic of REPRESENTATIONS, namely their correspondence to reality. The denial of CERTAINTY leads to intellectual humility, the exploration of ideas, and the progress of knowledge. The denial of TRUTH leads to intellectual arrogance, the stagnation of ideas, and the perversion of knowledge.
There are real challenges to the progress of science and human knowledge, but the absence of certainty is NOT one of them. It is a pseudo-problem, one that captures the imagination of people who are already resistant to the progress of knowledge.
Hostility toward knowledge has been a feature of the American landscape for decades. By advancing your form of Radical Skepticism, you are throwing your lot in with a group of people whose ideological and often fanatical hostility toward knowledge is a hostility toward civilization itself. Hostility toward knowledge stalls the progress of ideas, stifles efforts to reduce human suffering, and threatens the very survival of our species. Yes, literally.
It aint just about audio, MrPingPong.
