Freepers began a most engaging dialogue at the end of another thread! It is not only a fascinating subject - it also presents us with an opportunity to clarify ourselves and hopefully help us appreciate our differences and thus relieve some of the contention on various threads (most especially science and philosophy threads).
The subject is knowledge - which, as it turns out, means different things to different people. Moreover, we each have our own style of classifying knowledge and valuing the certainty of that knowledge. Those differences account for much of the differences in our views on all kinds of topics and the contentiousness which may derive from them.
Below are examples. First is PatrickHenrys offering of his classification and valuation followed by mine so that the correspondents here can see the difference. Below mine is js1138s offering.
Please review these and let us know how you classify and value knowledge! Wed appreciate very much your following the same format so itll be easier for us to make comparisons and understand differences.
PatrickHenrys types of knowledge and valuation of certainties:
1. Revelation: Spiritual understanding divinely communicated.

2. Prediction from scientific theory: I calculate there will be a partial solar eclipse this week.
3. Conclusion from evidence: I conclude from the verifiable evidence that ...
4. Sensory perception of something external to me: I see my dog is lying at my feet.
5. Acceptance of another's opinion: I provisionally accept the opinion of X (an individual or group) as knowledge because (a) I haven't worked it out for myself; and (b) I have what I regard as good reason for confidence in X.
6. Personal memory: I recall I had breakfast this morning.
7. Internal emotional state: I feel I'm happy, or I have empathy, compassion or sympathy for you.
Separate List for theological knowledge:
2. Faith: Belief in a revelation experienced by another.
2. Theological knowledge, indirect revelation: I believe in a revelation experienced by another, i.e. Scripture is confirmed to me by the indwelling Spirit.
4. Evidence/Historical fact, uninterpreted: I have verifiable evidence Reagan was once President.
5. Sensory perception of something external to me: I see my dog is lying at my feet.
6. Personal memory: I recall I had breakfast this morning.
7. Prediction from scientific theory: I calculate there will be a partial solar eclipse this week.
8. Trust in a Mentor: I trust this particular person to always tell me the truth, therefore I know
9. Internal emotional state: I feel I'm happy, or I have empathy, compassion or sympathy for you.
10. Evidence/Historical fact, interpreted: I conclude from the fossil evidence in the geologic record that
11. Determined facts: I accept this as fact because of a consensus or veto determination by others, i.e. I trust that these experts or fact finders know what they are talking about.
12. Imaginings: I imagine how things ought to have been in the Schiavo case.
2. Sensory perception of something external to me: I see my dog is lying at my feet. I am aware that this has limitations, but what choices do I have? I learn the limitations and live with them.
3. Personal memory: I recall I had breakfast this morning. Same limitations apply, except that they are more frequent and serious.
4. Logical conclusion: I can prove the Pythagorean theorem is valid and true. The trueness may be unassailable, but the conclusions of axiomatic reasoning are only as true as the axioms, which may be arbitrary. Outside of pure logic and pure mathematics, axiomatic reasoning drops quickly in my estimation of usefulness. People who argue politics and religion from a "rational" perspective are low on my list of useful sources.
5. Prediction from scientific theory: I calculate there will be a partial solar eclipse this week. I am not aware of any scientific theory that I understand which has failed in a major way. Some theories, of course, make sharper predictions than others. Eclipses are pretty certain.
6. Conclusion from evidence: I conclude from the verifiable evidence that ... Oddly enough, "facts" are less certain in my view than theories.
7. Acceptance of another's opinion: I provisionally accept the opinion of X (an individual or group) as knowledge because (a) I haven't worked it out for myself; and (b) I have what I regard as good reason for confidence in X.
I think skepticism is implied in the opening post of the thread, namely in its sorting of knowledge by degrees of certainty.
As a recovring behaviorist and amateur neuroscientist, I am aware that we quite literally don't know ourselves. I listed personal feelings at the top of my list of things I am certain of, but I did so with a touch of sarcasm. In the light of science, we are singularly unaware of what is going on in our heads, often to the point of not being aware of what we are feeling.
I note that this unawareness is seen by some as a virtue, leading them to assume that whatever is going on is not going on in their heads, but must be going on somewhere else. The construction of the brain doesn't lend itself to core dumps, so analysis of our inner workings is painfully slow and difficult.
Thinking about it doesn't solve the problem. Philosophers have been sayine "know thyself" for a long time, without much effect.
We are "designed" to make decisions and react quickly based on insufficient information. Our brains favor pattern recognition over detailed analysis. As you probably know, it is quite difficult to mimic this behavior with instruments. This is probably a good thing in the collection of data.
Thank you (uh, I mean thank me).
;)
For sure. But my current grumpiness is a big part of my charm.

I used to love cogitating about subjects like this. I need to see if all the tubes in my brain will warm up and let me participate.
Unsurprisingly invented by a minister, based on principles of alchemy, and popularized by an animistic physician...
Sesnse perception + comon sense (I see...)
Memory
Deductive - mathematic
Deductive - logical (same as above, plus macrocosm/microcosm fun)
Inductive/Inference based on past patterns ("It is Bill calling - he always calls at dinner time," "Bill will call at dinner time tomorrow")
Appeal to authority - "Experts say," "the history book says"
Revelation
Intuition
...And my least favorite, the statistical inference, i.e., "Americans feel the next Pope should be liberal" - the part-to-whole based on inference that the part is like the whole
As a side note, Asimov once wrote -- in one of his rare moments of saying anything favorable about theism -- that the development of Western science might be, at least partially, attributable to our tradition of monotheism. That is, among the Greeks, the observation of confusing or inconsistent facts could be shrugged off as due to conflicts among the gods. In the monotheistic worldview, however, there had to be only one answer, one cause, one explanation.

I cannot think of a single instance where the Greek philosophers shrugged off enigmas or paradoxes as the caprice of the gods. It would not have made much sense considering they did not regard the universe as ultimately contingent upon the gods. Maybe they just didn't bother writing about such perceptions, if they ever actually had them.
Wonder how Asimov would explain the Muslims stuck in the 14th century..
I think that the main difference between logical deduction and scientific theory is that logic is deductive whereas most conclusions or calculations from scientific theories are inductive in nature. For example, given the axioms of Euclidean geometry, it is deductively necessary that all right triangles will conform to the Pythagorean theorem. It is just as impossible to find a right triangle that varies from this theorem as it is to find a square circle. The concept of a right triangle in a Euclidean geometry that doesn't follow the Pythagorean theorem just doesn't make sense.
With regard to scientific theory, OTOH, an observation that contradicts the theory is at least sensible. That is, it is not impossible to find a counterexample to a theory; one just hasn't been found, which is why the theory is accepted. A good example would be the calculated force of gravity between two objects, as given by the theory of general relativity (or equivalently in most situations, Newton's law of gravity). According to theory, the calculation works no matter which two objects we use to measure the force of attraction. However, we haven't measured the attractive force between EVERY two pairs of objects in the universe. Logically, it is possible that if we somehow measure the attraction between two galaxies that are a couple billion light years away from us, that this will not adhere to the accepted scientific theory. This would have profound implications for our scientific understanding, but it is not impossible that our scientific understanding is incomplete or incorrect.
Plus a theory of why those regularities occur. It just so happens it doesn't matter whether your visualization is geocentric or heliocentric, but you can't easily find the regularities without a visualization.
For those inclined to attribute science to Western theism, I ask why Eastern theism isn't more suited to science. It is certainly more easily conformed to modern physics.
Thanks for the post AG. I saw your discussion on that other thread and thought it was interesting. Looking forward to reading through this thread on the weekend. Thanks for all that you have done.
Since I wrote the sentence you are responding to, let me explain. I was actually thinking of Newton when I inserted the phrase "major way." My writing isn't always clear when I'm in a hurry, but I was thinking that Newton still works perfectly well within a wide range of parameters. It certainly works perfectly within the range of what we can experience without instruments.
Good theories do not get proven wrong. They just get assigned or limited to a range of conditions.
