Knowledge defined
Pre-Gettier and Post-Gettier we generally and more or less plausibly hold (1)
Knowledge is justified true belief. We might outline this as follows.
S knows P if and only if
Alone 1-3 are necessary and together they are sufficient for the predication of knowledge to S. Post-Gettier many epistemologists came to hold that some fourth property or condition need be provided, but we can ignore that for now.
- S believes P
- S has evidence for P
- and P is a true fact about the world
Skepticism defined (more or less)
Now, skepticism captures a broad range of theories which hold doubts about knowledge or its properties (1-3). Some might be
[INDENT]i. Doubt as to our our justification (evidence), that it is lacking in some particular cases (everyday, mundane, weak skepticism),
ii. Consists of (only) falsehoods (error theory about knowledge),
iii. Possible knowledge is doubtful (Pyrrhonian skepticism)
iv. Or is radically and systematically unjustified (Cartesian skepticism).
[/INDENT]Some derivative positions
I wish to clarify a few derivative positions which combine the properties of knowledge and skeptical approaches. We might approach these derivatives through this outline:
a. Do not exist
b. Is always inadequate or insufficient
c. Is always false
So, by combination of a. and 1. we get
a1: Beliefs do not exist
And so on...
a2: Evidence does not exist; Justification does not exist
a3: Facts do not exist; true and false facts do not exist
b1: Beliefs are always inadequate or insufficient (all beliefs are not really beliefs)
[INDENT]b1i. I might say, "You don't really belief that." Thus, I judge the adequacy or perhaps authenticity of your belief.
[/INDENT]b2: Evidence is always inadequate or insufficient; justification is always inadequate or insufficient
b3: Facts are always inadequate or insufficient
c1: Beliefs are always false
c2: Evidence always leads to false conclusions or can never have true conclusions
c3: Facts are always contingently false, even if they could (possibly) be true
Beliefs
Now in my exploration I stumbled onto a weird one. "Beliefs do not exist."
This is quite strange for it seems plausible that one might argue, "Look, your belief isn't really a belief."
So the same with our Knowledge defined section, we might outline belief as follows.
S believes Q if and only iff
[INDENT]...
[/INDENT]And that's where I get loopy. What are the necessary and sufficient conditions for belief or to say that S beliefs something? What are your thoughts on this particular issue or anything I've given above?
Knowledge is justified true belief.

C.S. Peirce held that to believe a proposition is to be willing to use that proposition in an argument. Another, somewhat different notion is that to believe that p is to accept p as true.
There is, btw, an ambiguity in the word, "belief". The word can refer either to a mental state of the acceptance of a proposition, or else, it may refer to the proposition that is accepted. So, if A believes that p, the term, "belief" may refer either to A's mental state, or to p itself.
One important thing is to distinguish between believing and knowing. There seem to be two main distinctions between the two.
1. We can have false beliefs. We cannot have false knowledge.
2. Belief may have little justification, or even none at all (faith). To know, the knower must have adequate justification, however that is to be analyzed.
Your 2 merely restates all that I have said. Whatever sense of "justification" one's conception of "belief" has, it's necessarily going to be a different kind of "justification" from one's conception of "knowledge," if that conception of "belief" factors into one's conception of "knowledge."[/qoute]
What is the difference between a belief's conception of justification and a knowledgeable conception of justification. Is it coherence? This seems to be what I find highly skeptical about this process. does this idea imply that knowledge can only be justified by other knowledge? If so, what's the point of it all?:muscle:

of what ('quality') is the 'knowledge' of which is spoken?
Well, those are very broad categories. I'm really not sure of the relevance, though.
If (in fact) S believes Q, has (sufficient) evidence for Q and Q is true, this is as supposed a sufficient condition for S's knowing Q. Whether S utters or performs a speech act involving Q does not seem to modify the "quality" of S's knowing. It might show that S has a poor ability to express Q verbally. It might say something about the expression of knowledge. What you seem to be saying is that knowledge is determined by whether or not a speaker utters statements corresponding to it.
But how might we ever confirm that S knows?
It seems that knowledge is essentially public in some way or other, and your quote is largely unhelpful.

Daniel Dennett attacked PMS Hacker, by way of expressing his own beliefs, in a very emotionally charged and frustrated and dogmatic manner.
Most analytic philosophers and neuroscientist agree with Dennett.
I certainly wouldn't want to say D.D. didn't expend much time on the subject. He's spent a majority of his career writing about consciousness, etc--even if I think he's wrong.
So what you've said seems false.
But this vein of that seems important it. Public criteria constitutes what it means to say that S believes Q.
Are you saying we should observe the agent and somehow that will give us one or all of the necessary conditions, and thus the sufficient condition, for saying that agent believes something?

Premise 1 is tautological.
How do you justify premise 2?
Certainly every thing can be viewed as in a context. But necessarily so?
This argument just looks like pissing in the wind.
Means nothing. Proves nothing. Another cognitive fallacy...
"The strength of a 'belief' is inversely proportional to the amount of critical thought expended on the subject of that 'belief'"
Knowledge is just a poor and obsolete term. All 'knowledge' is tentative and contextual. Public or otherwise.
A person says that he believes such and such, and that is all there is to it. It is his 'truth'. What has the 'public consensus of criteria' to do with it? Are you referring to 'language'?
We cannot. We can safely accept his assertion of what he thinks that he 'knows'.
S only thinks that he 'knows' something (most often a function of ego). S 'believes' that he 'knows' something ('knowing' sounding so much more comfy to the ego than 'believing'). It is not for me to confirm or deny what another thinks or believes. It is reality/truth for him, a feature of the greater Reality/Truth.
What can be verbally expressed is no more than metaphor, and is not the thing, not 'truth'. There are no words at that depth of understanding/experience'.
If Bob says that he believes something, or if Bob says that his nose itches, is sufficient for me. What possible reason would I have to argue with such a statement? His assertion is 'sufficient condition' for acceptance.
There is a social component to 'truth' - this is the public consensus of criteria referred. A person can say the sky is made of gold, but based on consensus, we can deduce what he speaks is not 'truth'. What one says is not "all there is to it". Clearly, there is a consensus factor based on many objective methods of rationalization (science, logic, etc.)
Knowledge is just a poor and obsolete term. All 'knowledge' is tentative and contextual.
I understand what you're saying: Each consciousness can only perceive subjectively, we cannot view from an objective lens. Meaning, each perception is an independent truth, "a feature" of the 'greater reality'. Fair enough, I can't refute that.
However, I don't think our perception is as nonsensical and detached as you make it sound. Clearly, there is universal consensus on some matters.
But who claims that knowledge is objective. Some proposition does not need to be objectively or necessarily true for someone to know it. You cannot refute that because there's nothing to refute, there's only an error.
If by universal you mean "inter-subjective." I'm sure you meant that. I don't mean to correct you, just to perhaps add another "word" so that someone might see it and not start thinking that you're talking about "God."
I was only assuming that our conception of belief presupposes justification for the purpose of showing you that even if belief does presuppose justification, it must be different from the kind of justification presupposed by our conception of knowledge.
I was not saying that belief presupposes or necessarily has justification. The difference, in large part, is that justification as presupposed by our conception of belief does not exist in any meaningful sense while justification as presupposed by our conception of knowledge does not.
We don't need to justify our beliefs in the since that we have to provided evidence for them.
But to say of someone that he believes this or that, there must be a few obvious necessary conditions. Or maybe there aren't. I'm looking for a position here.

Hm, this one really has me here.
I can think of quite a few examples in which I cannot find any necessary conditions. An abundance of critical thought does not have to precede a belief claim. Joe could shout one of your 'trivial beliefs', "Jane, I think your shirt is nice!", and believe it. Where is the necessary condition here? No critical thought was involved, it's just a preference, a *feeling*. A 'substantial belief' seems as though experience or critical thought, of some sort, must come before. Here I can find some necessary conditions, but language is so diverse, meanings so twisted, we'd have to quite literally look at each and every belief proposition to "make sure". And even then, what criteria would we follow? I mean, only the speaker knows for sure, right?
It gets even trickier if we speak of those with mental illness, such as schizophrenia. Where do hallucinations lie within belief?
So, for instance, people clinically diagnosed as mentally handicapped or psychotic seem to have beliefs, but certain classes of beliefs are generally denied to them as bearers of those beliefs. So, for instance, the belief that one is in a padded room might be legit while the belief that pluto has martians on it (uttered every other year) is not. A random sequence of utterance that happens to sound like "I believe X" would not be attributed to a person. For instance, we wouldn't attribute beliefs to a parrot.
On hallucination: Suppose you're induced into a coma and someone "injects" (by some means) into your brain "the belief that X"; I'd doubt that we'd say you legitimately or genuinely hold that belief. On the supposition, we'd simply say that you were induced to say it or you got it in the wrong way. There seems to be a "coherency in acquisition."
Even if God decided to tell you this or that, I'd still think it mysterious that you could even get a belief at all because God's supposed to be outside of the normal flow of things. Getting beliefs through flux seems suspect. We generally hold that people must get their beliefs through some standard and normal process.
So the reason for our believing something or having the belief at all seems to be necessarily within a certain class of possible reasons. And perhaps this is a necessary condition.
For instance, in order for me to genuinely say, at all, that I believe in God. I must go to church for some number of years, have religious parents, perhaps, etc etc
