Closing Remarks
I think some of the problem I've found in arguing about epistemology comes down to people not really talking about the same thing. Maybe this comes from ignorance, or simply because people are working off of different presuppositions. As a Presuppositionalist, I tend to think this is more the case.
When I am speaking about epistemology, I have a very specific definition of knowledge in mind. I am not using the term to mean "things we are certain about", but things which we have a epistemic justification for believing true. An epistemology is a theory of knowledge. When we start thinking in-depth about our worldview - our philosophy - we need to answer questions like "how do I know" and "what is knowledge" and "why". These question can not be dismissed with pat answers like "seeing is believing" or I just know. Now you can live your whole life as a functional human being without addressing those questions, but you are still function under assumptions that answer them by implication.
So when we speak of epistemology - it is not asking simply what we a sure about, but what is true and believed and justified. Simple certainty applies to "if my car runs out of gas, the engine will stop". What is debatable, is if knowledge applies here. Can we know the future? Can we conclude that all crows are black because we have observed 10,000 black crows - or a lifetime of crows. Can one induce universal truths from particular occurrences. Plato tried to answer this over a thousands of years ago.
Another question is if knowledge is personal or impersonal. What I mean is this, can one person know A, and another person know not-A. This is personal knowledge. But if knowledge is truth, then can someone know something that is in-fact, false. One the other hand, if we say that knowledge is universal truths, it becomes much harder to justify knowing it. If we say the knowledge is just what one is reasonable certain about (like when I cross this bridge, it will not collapse), then knowledge is no longer universal. People can "know" contradictory things.
Also, if knowledge is truth, what is true. Not only do we need to understand what truth means - beyond a metaphor - but we need to say how we know a truth from an falsehood. Is the color blue true or false? Can we "know" the color blue? How do we justify this knowledge?
There are many difficult questions to answer if one is to have a cogent and rational epistemology. But we can always reject "rational" as being "rationalism" or idealistic. I suppose one could argue that knowledge is more than what we can think cogently about. We can do as some and embrace mysticism. But this rejection of rational knowledge is self defeating. If we can not speak of knowledge in terms of cogent ideas, then we can not give a logical defense truth. It's a mystery. And speaking of logic, who says the laws of logic are universal? In the eastern philosophies, they don't believe reality is so "black and white". To them, truth is a matter of grays.
Definitions are often the heart of disagreements. People like to think their definitions are true and other's are false. The problem with this is definitions are tautologies (if you assume logic), and it is more important to be consistent with your definitions, then have the "right" definitions. I define knowledge as "justified true belief" and justification as being deduced from a-priori truths (or justified by immediate enlightenment from God). But others will argue that I am literally wrong. The problem is that being wrong or right does not apply. There is not single definition of "knowledge" or "car" or "optimism". The issue is not a matter of right or wrong but of good or bad. A bad definition will not get the job done. Maybe it's self defeating or too vague. Maybe it contradicts how you use other terms. The point is to be specific and be consistent. And understand how other people are using terms. Ask them to define their terms, and be ready to define your's. Only then you can defend them as good and useful and coherent.
Do our terms have to conform to Scripture? Yes and no. Of course, when we are reading Scripture, we need to understand the terms as they are meant. Only then can you reason correctly. But when we are speaking
about Scripture, or about philosophy, we want terms that we understand and are clear. We don't need to restrict ourselves to using
only the words found in the Bible or even exactly as they are used in the Bible. Scripture doesn't use terms univocally throughout the text. And we can invent knew terms that help us explain our thoughts. Read any theologian to see examples. You won't find "archetypal" or "etypal" in the bible. These terms were invented to help explain some ideas about the relationship between God and man. These are certainly extra-biblical in that the ideas are not explicit in Scripture. So to is the idea of the Trinity. What matters is being clear, and avoiding equivocating.
Scripturalism is an answer to the questions of philosophy. It is not an answer to how we "know if our car is going to need gas tomorrow". That is a different beast all together. It answers the question of epistemic justification. So by definition, there are some things it will justify as knowledge, and other's will not. Other epistemology's will, by definition, produce a different knowledge set. By empiricism, one can know that a tree is brown, and man evolved from apes. It will say we can truly "know" how far it is to the moon, and how old the universe is. It can tell us what we had for dinner, and that there is no God. These are all equally valid bits of empirical knowledge. On the other hand Scripturalism can not justify what we had for dinner, but it will justify that God created the world, and Jesus died for the sins of the elect, and even that 2 + 2 = 4. It will tell you how best to love your neighbor - but not which color looks best on you. It doesn't justify knowing that George Bush is president, but it will justify David was the king of Israel.
The point is, that different epistemologies will justify different answers to what we can know. But we can not prove epistemologies based on the knowledge they justify. Effectively, it matters little that Scripturalism won't justify knowing where the best price of tomato soup will be found, it also doesn't justify that walking on water is impossible. I know Jesus walked on water, and, although this is based on epistemic
opinion, I'll still go to Safeway for tomato soup.
I'd love to edit this down and clean it up, but for now, I'll spell check it and wait for other opportunities to discuss these issues. Hopefully, people can keep things a little less personal and more rational. Me, I have a great deal of respect for things that are rational. Rationalism I can't abide.
And please read those articles on Wikipedia about epistemology and empiricism and rationalism. That will help you with the background information you need to keep things philosophical.
