You seem to say that something is justified if and only if the community agrees. How many members of the community need to agree? Isn't it possible that the community is irrational? Isn't it possible that they believe a poorly justified belief is well-justified, or that a well-justified belief is poorly justified? Or are you saying that "well-justified" is, by definition, whatever the community agrees on? Doesn't that strike you as obviously wrong? Also, what if someone justifies his case, and it is initially seen as unjustified, but after some time, even though no change has been made to the arguments, the community changes its mind? Does the belief go from unjustified to justified even though none of the justifications have changed? Wasn't it well-justified all along (given the justification hasn't changed at all), and it's just that people now realize it?

My point is we can't judge knowlege 'community standards aside', or it just becomes belief. If this man explains his position in full, and we (the community) do not agree that his reason for believing is a good one (justified), then to us (remember, were the community, and we set the standards by which knowledge is judged), we have knowledge, and he has false belief. I am saying that justification comes from the attempt to divorce our beliefs from subjectivity, by appealing and accepting a community as judge.

I agree with much of what you have written. I am however somewhat confused by the subjective part..
The justification I use for accepting a belief’ is dependent on my presupposing the belief to be true; (so it is that many inclinations toward belief’ do not become belief’) that is, in accordance with presupposing belief’...given that my presupposing is representative of the community from which I hail.

Following Wittgenstein; It is only by belief first and doubt later that learning can take place.





I wasn't sure how to take this, so I think charity dictates 'playfull irony'?

I promise you my wisdom is nothing but toilet paper.nod I'm just trying to wipe the crap away, and be left with a shiny, clean issue.

Isn't saying you believe something equivalent to saying you presuppose it is true? If that is the case, then justification=belief and knowledge=true believed belief, or true belief (and we can agree I think that this is problematic).

Makes sense to me.

Not exactly
Example...this time I will quote Wittgenstein. “As children we learn facts; e.g., that every human being has a brain, and we take them on trust. I believe that there is an island, Australia, of such and such a shape, and so on and so on; I believe that I had great-grandparents, and that the people who gave themselves out as my parents really were my parents, etc. This belief may never have been expressed; even the thought that it was so, never thought.”

So it is that when I say, “... dependent on my presupposing the belief to be true...” I am refering to those kinds of presupposing.

I amm saying that a point of view is required to set the question in. I can think of three possibilities.

1) Subjective: All beliefs are justified from a subjective point of view. If you didn't think you had justification to hold a belief, you wouldd believe something else.

2) Objective: By this I mean a 'God's eye veiw'. We can only imagine what this would entail.

3) Intersubjective: Within a certain group (which will vary according to the specific circumstance) there will be an explicit or implicit criterea for justification. Within the scientific community, there is the scientific method and peer reviews, for example.

I am suggesting that what we generally call knowledge is beliefs that meet the criterea of a particular community.

How many members of the community need to agree?


It's a baldman's paradox. The 'fuzzy' thinking we do tells us that X is enough, Y is too few, and Z is ambiguous/debatable. If you can give me an answer to the baldman's paradox, then apply it to your question, and it should be right.

Isn't it possible that the community is irrational?


How is rationality judged? By community standards. So unless you are judging by the standards of another community, then no.

Isn't it possible that they believe a poorly justified belief is well-justified, or that a well-justified belief is poorly justified?


Who is deciding that their poorly justified beliefs are well justified, or vice versa? Whomever it is, they are applying standards of justification. Typically, when we are speaking of knowledge, we imply a justification standard held by a community, not just an individual.

Or are you saying that "well-justified" is, by definition, whatever the community agrees on?


Within the context of that community.

Doesn't that strike you as obviously wrong?


No. Perhaps if you gave me an argument as to why it was wrong, I would understand.

Also, what if someone justifies his case, and it is initially seen as unjustified, but after some time, even though no change has been made to the arguments, the community changes its mind?


It happens all the time. Old knowledge is supplanted by new knowledge. It was known that the world was flat, but now it is know that it is round(ish).

Does the belief go from unjustified to justified even though none of the justifications have changed?


I don't understand this question at all. If the justfication hasn't changed then it hasn't changed. If it has then it has.

Wasn't it well-justified all along (given the justification hasn't changed at all), and it's just that people now realize it?


From what point of view? From a subjective POV, I'm sure the belief was perfectly justified by the holder of the belief from the moment he believed it. From the communities POV, it was not justified until the data or criterea changed.

Presuppositions without intent? Sure. I don't think that rationally chosen presuppositions are much different. We believe them because we have reason to. They are reasonable. Justification is the word we use to descibe the reasons that we have to presuppose something to be true. In discussions of knowledge, typically justification (as in JTB) refers to the reasons that 'we all' (society in general) agree are sufficient to presuppose something is true.

Suppose the argument remains the same, but the community's criteria change such that it is initially thought of as unjustified, but then later thought of as justified. If we are to accept your redefinition of "justified," then whether or not a belief is "justified" can change independent of the actual justifications. What's more important in determining whether something is justified is whether enough people believe that it's justified, not what the actual justifications are. To say something is "justified" tells us only what the community is willing to believe, it tells us nothing about the belief or the reasoning itself.
From what point of view? From a subjective POV, I'm sure the belief was perfectly justified by the holder of the belief from the moment he believed it. From the communities POV, it was not justified until the data or criterea changed.
Why does it depend on a point of view at all? Indeed, people and communities have their respective points of view, but is that all there is to it? The answers to some questions are entirely contingent on point of view. The value of things, the difficulty of tasks, etc. are such questions. The mass of an object (neglecting relativistic effects) is not. People might have different points of view about such things, but that doesn't mean that all we can say is what a person's point of view is. We can also say which points of view are wrong, and which are correct. You're telling us that justification is of the former kind. That to say something is justified is really just to say that it is justified from a certain point of view. I can see no reason as to why this is though. People who believed that a flat-earth belief was justified were wrong, such a belief is not justified. To them, yes it was justified, but they'd be wrong. They're not just wrong according to us, they're wrong, plain and simple.

Suppose I liked chocolate as a child, but now don't. I would never say that I was wrong about whether chocolate tastes good. Back then it did, now I feel differently. As a child, a certain task may have been difficult for me, now it's not. I wasn't wrong back then, I was just different. On the other hand, when we look back at previous standards of justification that we've scrapped (I'm talking about a person's own standards that he himself has scrapped in his lifetime), we don't say that those were just different standards, we say that those were wrong standards. Whereas we would never look back and say that we were wrong for liking chocoloate, we can and do look back and realize we were wrong for believing in X simply because Y told us; we realize that "because Y says so" is an incorrect standard for justification.
It happens all the time. Old knowledge is supplanted by new knowledge. It was known that the world was flat, but now it is know that it is round(ish).
You mean it was believed that the world was flat. Unless you mean to say that we can know things that are false, in which case why call it knowledge at all?

Could you describe this 'actual justification'? What are the criteria for it? and why?

Why does it depend on a point of view at all?


I thought that was described in Morrie's first post.

Indeed, people and communities have their respective points of view, but is that all there is to it? The answers to some questions are entirely contingent on point of view. The value of things, the difficulty of tasks, etc. are such questions. The mass of an object (neglecting relativistic effects) is not. People might have different points of view about such things, but that doesn't mean that all we can say is what a person's point of view is. We can also say which points of view are wrong, and which are correct.


We can say it, but we are judging it so by a set of criteria. Where did this criteria come from?

You're telling us that justification is of the former kind. That to say something is justified is really just to say that it is justified from a certain point of view.


Yes.

I can see no reason as to why this is though.


I can see no alternative.

People who believed that a flat-earth belief was justified were wrong,


We belive so. It is a justified belief.

such a belief is not justified.


Not anymore.

To them, yes it was justified, but they'd be wrong. They're not just wrong according to us, they're wrong, plain and simple.


When did you gain the power to supervene you own beliefs? You believe they were wrong. I agree. Most everyone I know does too.

Suppose I liked chocolate as a child, but now don't. I would never say that I was wrong about whether chocolate tastes good. Back then it did, now I feel differently. As a child, a certain task may have been difficult for me, now it's not. I wasn't wrong back then, I was just different.


Yes. Good analogy. I ask you "does chocolate taste good?" and you must answer (if you are honest) "no". I ask you the same question when you are a child and you must answer "yes". Both are correct answers, within the historic context they are placed. Now, until you criteria for judging chocolate changes (you personal tastes), the answer must always remain "no".



On the other hand, when we look back at previous standards of justification that we've scrapped (I'm talking about a person's own standards that he himself has scrapped in his lifetime), we don't say that those were just different standards, we say that those were wrong standards. Whereas we would never look back and say that we were wrong for liking chocoloate, we can and do look back and realize we were wrong for believing in X simply because Y told us; we realize that "because Y says so" is an incorrect standard for justification.


What is the difference between a taste for chocolate, and the belief that the earth is round? No one tells you the you like chocolate or not (I hope), but people tell you that the earth is round. They also tell you what the appropriate way of experimenting, so you can find out yourself. They teach you the formulas, build you the telescopes, tell you that logic is to be relied on as opposed to fancy. You couldn't do this youself. If you could, then we would have no need for the concept of knowledge. Belief would be good enough.

You mean it was believed that the world was flat. Unless you mean to say that we can know things that are false, in which case why call it knowledge at all?


The word truth can be intentional (conceptual) or extentional (with referents). Intentional takes us back to beliefs. Stating that we have any access to extentional truth is ludicrous. Both historically and rationally. We don't have knowledge of extentional truth's.

No so. We cannot prove knowledge directly, but its not the same as having no knowledge. Some fact have never changed. Physical shapes, for instance, for as long as any marking were made to the fact have been represented very similarly. Is it not than an external truth that we've always (supposing the existence of history, of course) percieved humans to have two arms and two legs?

"With no relation to class or social background, whether it suits them or not, people yearn for a dream. Sustained by a dream, hurt by a dream, revived by a dream, killed by a dream. And even after being abandoned by a dream, it continues to smolder from the bottom of one's heart... probably until the verge of death. A man should envision such a lifetime once. A life spent as a martyr to the god named "dream."

I never said we had no knowldge, I said we had no access to extentional truth. Big difference.
