@igm,
Quote:Knowledge is justified belief therefore belief is unjustified
One criteria for an assertion to be called knowledge is that the assertion must have some accuracy and relevance in relation to "empirical reality". There must be a frame of reference that is shared by all, so that any assertion can be proven true or false by experiment.
This criteria does not apply to an assertion we can call a belief. Assertions we would put in this category are in no relation to our shared frame of reference, and so cannot be proven true of false by experiment. Justification doesn't enter into it, same as you don't need justification to dream about winning the lottery. It's just something some people do.
So, the way I see it, there is a big difference between what we might call 'uncertain knowledge' and 'belief'. Uncertain knowledge, theories we suspect are right, but don't know for sure yet, for instance, relate to "empirical reality", and so cannot be defined as beliefs.
And beliefs cannot be defined as 'wrong knowledge', simply because that is not what they are. There's no direct relation with knowledge at all, only creative imagination. That does not make beliefs unjustified. There may be many good reasons to believe in god, even if that belief can never become knowledge. The reasons just aren't scientific.
