Personal anecdotes and conclusions!
Well, after perusing your post, I have to "spew forth a definition" so we can know

what we are talking about.
Epistemology is the branch of philosophy that studies knowledge. It attempts to answer the basic question: what distinguishes true (adequate) knowledge from false (inadequate) knowledge? Practically, this questions translates into issues of scientific methodology: how can one develop theories or models that are better than competing theories? It also forms one of the pillars of the new sciences of cognition, which developed from the information processing approach to psychology, and from artificial intelligence, as an attempt to develop computer programs that mimic a human's capacity to use knowledge in an intelligent way.
But you wanted anecdotes and general conclusions!

It seems to me that what you are asking for is an education in epistemology. Now, I am certainly not qualified to serve up such a thing as I do not hold the "anecdotes and conclusions" of professional philosophers in too high a regard. However, I am prepared to serve up my anecdotes and conclusions for your entertainment. (In all honesty, I first caution you that the professional physics community holds that I am a crackpot and has refused to publish almost every paper I have ever written.)

But we can lay that aside as unimportant.
From my perspective, the first problem is that philosophers assume that the human language they use in their studies of knowledge is the fundamental medium within which to express differentiation between those categories of knowledge: i.e., I hold that they are assuming validity of their own knowledge of communication. It makes it difficult to consider the question if you assume you know the answer (even if you argue it is only a small piece of the answer - which it isn't). Now I have a Ph.D. in theoretical physics but left the professional academy because, by the the time I obtained my degree, I had become fully convinced that the physics community had totally dropped the ball on this very issue. They had put no serious thought into how one distinguishes true (adequate) knowledge from false (inadequate) knowledge; they simply presumed they knew.

You don't want to be a Solipsist do you?

(That's an anecdote!)
Now, let's add the definition of Ontology:
Ontology is the theory of objects and their ties. The unfolding of ontology provides criteria for distinguishing various types of objects (concrete and abstract, existent and non-existent, real and ideal, independent and dependent) and their ties (relations, dependences and predication).
And how "pray tell" are we to describe "objects" without a solution to epistemology. Some professional philosophers have told me that these are separate fields of philosophy.

Another anecdote!
It is my position that the only starting point in this mess has to be abstract as we must assume we "know" nothing for sure while, on the other hand, our knowledge (valid or invalid) changes all the time. It is my opinion that the only mechanism under which we can discuss things which we have not yet defined involves the idea of sets. So I thought I came up with an excellent way of expressing this start point. That starting point is introduced in the thread
"Can Everything be Reduced to Pure Physics?" but I have not seemed to interest anyone except "saviormachine". (You asked for anecdotes didn't you?)
So, from that starting point, I proved that the following equation must be valid.
<br />
\left\{\sum_i\vec{\alpha_i}\,\cdot\,\vec{\nabla_i}\,+\,<br />
\sum_{i\not=j}\beta_{ij}\delta(\vec{x_i}\,-{\vec{x_j}})\right\}<br />
\vec{\Psi}\,\,=\,\,K\frac{\partial}{\partial t}\vec{\Psi}\,=<br />
\,iKm\vec{\Psi}
I first proved (if you accept the idea of "proof"

) the above relationship had to be true sometime in the late sixties, but I couldn't solve it. (An updated version of my proof can be seen in the
"Nuts are us" forum.) Not being able to find solutions to it left me somewhat in a quandary (note that the index range has to be infinite which complicates the problem considerably). When I finally did comprehend how to find solutions (1982), the whole thing became almost trivially obvious so I wrote up a paper for publication. I was turned down by every journal I submitted it to. I don't think a referee ever saw it. Everyone of them said it was not within the subject matter of their journal; the physicists told me it was philosophy, the philosophers told me it was mathematics and the mathematicians told me it was physics.

:rolf: rofl:
In 2002, my son in law suggested I learn HTML and self publish on the world wide web. So the solutions are there if you want to see them. The problem is that I don't think anyone on this forum has either the education or the attention span to follow what is there. And that brings me down to my conclusion: I think I have solved the problem of the fundamental nature of reality and have produced the only valid derivation of Quantum Mechanics extant. And it raises some very interesting issues not even dreamt of by our "great thinkers".
But I am a crackpot and not to be listened to by Novices. When I was a graduate student I brought up some of my observation to the chairman of the Department of Physics. When I showed him some of the relationships I had realized (in coming to the conclusion my equation had to be valid) he said, "What you have done makes sense, but don't show it to any of the other students, it will just confuse them!" That was when I realized I was attending a religious institution.

But I have to admit he was right. If you want to see a current version of exactly that same discussion and see the confusion it generates, check out
"A Thought Experiment" (also on the "Nuts are us" forum.) And, hypnagogue, if you object to my use of that reference to the forum as uncivil or insulting, I would like to point out that I did not come up with it. It was used by a number of mentors posting to that forum.
Talk to me and I will talk to you.
Have fun -- Dick
