adrianhaffner a dit:"you cant know anything, because anything you think you know could turn out to be merely falsely believed"
i agree. this statement is speaking about real events, not theoretical ones, and therefore i believe it applies.
this is ALL that i am saying, if you agree with this, then you agree with the whole point i am expressing on this thread
anything you think you know can turn out to be false in the future, and therefore you cannot know anything. This applies to ANY proposition 'p', you cannot know any proposition to be true
adrianhaffner a dit:so can we agree then, that:
1.*in theory* knowledge must require truth
2.*in reality* knowledge, by theoretical definition, can never happen because it can never be proven that that knowledge is true, or was even true to begin with, therefore any 'knowledge in reality' (i know this is contradicting) would or could be false, because nothing is true..
1. yes i agree, knowledge requires truth, every definition of knowledge that has ever been formulated, has made this absolutely explicit
if something isnt true, it can be (falsely) believed, but it cannot possibly be known
2. yes i agree, any proposition that is believed to be true, could turn out to be false, this is why knowledge is impossible
adrianhaffner a dit:now i know you're going to say that this is belief, because that is how it seems... but the difference is that knowledge is something that must have been witnessed (percieved) at some point, and a belief does not.
but even the fact that you have 'witnessed' something does not guarantee that it is true, your senses can lie to you, so whether you perceive something or not, either way you cannot know it
adrianhaffner a dit:please show me any definition of knowledge that you like (a link so i can see it is valid), and i will show you why knowledge is different than truth and belief..
the standard epistemological definition of 'knowledge' ever since Socrates, has been:
Justified, true, belief
there has been no other competitor for a definition of knowledge besides this one, so it follows, that in order to know that p:
1. you must believe that p
2. p must be true
3. your belief must be justified
adrianhaffner a dit:witnessing something that to the observer is concluded 'true' by way of 1 or more of the 5 senses. or in other words: introducing the notion of fallibility
this does not distinguish knowledge from mere belief
you can perceive something with all 5 senses, and 'conclude' that it is true, but it might still be false, your senses can trick you
