All knowledge is false. As one man has said, "it (knowledge) is like so many ropes of sand." Why would I make such a seemingly false and reprehensible statement? I feel that example will elucidate the problem far easier than explanation.
Let us ask the question:
"What is an apple?"
To put the question mathematically, we would write it out as 'A = ?' where 'A = apple' and '? = desire to know'.
You might say to yourself, "ah, that is simple. An apple is a round fruit."
Or mathematically, 'A = B + C' where 'B = round' and 'C = fruit'.
But that answer really shows that you have already fallen into the trap which is knowledge, because it only brings up more questions:
"What then is round?"
"What is a fruit?"
Or, 'B = ?' & 'C = ?'.
Come the answers, "well, round is the state of having quantifiable dimension, but no sides. And fruit is a seed-containing ovary which is produced by certain plants." (Or something along those lines, for the example these are adequate descriptions.)
Otherwise, 'B = D + E + F' & 'C = G + H + I + J', where 'D = state', 'E = dimension', 'F = sides', 'G = seed', 'H = ovary', 'I = produced', and 'J = plants'.
Very wise these answers will seem to you, surely they give the solutions that are sought. However, a bit of scrutiny will show that this is not so, for we now must ask:
"Well then, what is a state?"
"And what is a dimension?"
"What are sides?"
"What is a seed?"
"What is an ovary?"
"What does produced mean?"
"What are plants?"
All of these questions, of course, COULD be answered with more variables. But I hope that by now you can see how truly spurious that would ultimately be, given that you could continue to insert variables until you are blue in the face and still not come up with a simple, definitive answer. All that you will turn up is MORE QUESTIONS and MORE VARIABLES; back and forth and back and forth, ad nauseum...
Knowledge is merely the symbolization of wisdom and understanding, ie. experience, for the purpose of convenience in communication (yes, this statement too falls victim to the above form of investigation). We could say that knowledge comes about when we seek to go beyond pure intuition.
Now, let it not be said that knowledge is without merit. On the contrary, only a fool would assume such. I am just suggesting that everyone should recognize the boundaries and limitations of every tool in his/her repertoire.
