With regard to knowledge and doubt in On Certainty:
6. Now, can one enumerate what one knows (like Moore)? Straight off like that, I believe not. - For otherwise the expression "I know" gets misused. And through this misuse a queer and extremely
important mental state seems to be revealed.
What is this mental state? — Fooloso4
Knowledge claims are epistemological. Justification does not mark a distinction between epistemological and non-epistemological knowledge claims. — Fooloso4
Science is a form of knowing in a participatory and a practical sense. We know the world, in the sense of participating in it, via science. It is practical too in the that it is a practice, a know-how. Propositional knowledge though, it seems to me, requires observation. I know I have hands because I can see them, observe myself using them and so on. I know it is raining when I am out and I feel the rain on my body and see the drops falling. In those kinds of cases, of which there are countlessly many in our lives, we cannot be mistaken, barring faux-doubt and bizarre thought-experiment scenarios, which I don't believe deserve our concern. — Janus
When you say "So, I could say without sounding weird that I have good reasons to believe I know X, but that there is a small chance I could be mistaken." I have no problem agreeing with you because it is not a claim that I know, but a claim to have good reason to believe that I know. And this highlights the strangeness of saying that I could know, without knowing that I know. For me, if I don't know that I know, as I say I do in cases like 'I am a human being' 'my body is bilaterally symmetrical (more or less)', I have hands and feet'. 'My head sits on my shoulders' and so on endlessly, then I would say instead that I don't know, but I believe or don't believe this or that, or I reserve judgement. — Janus
I see, not knowing and doubting, but believing and doubting as more inextricably tied. The problem I have with the idea that knowing involves uncertainty or defeasibility, is that it seems weird, inconsistent or incoherent. to say that you know, but that you could be mistaken. — Janus
Epistemological considerations may come much later but knowing and doubting do not. It is not clear what the distinction you are making between knowing and doubting and their epistemological uses. If the point is that epistemology as an branch of philosophy arises later then yes, of course. — Fooloso4
Since hinges can and do change, even if only rarely and slowly, epistemological considerations are not off the table — Fooloso4
But recall that Wittgenstein regarded the ordinary meaning of "to know" to not imply infallibility, in the sense that even if a fact P necessarily implies another fact Q, "knowing that P" does not necessarily imply Q. — sime
This stems from his epistemic consideration that in a literal sense nothing is knowable in the sense demanded by a philosopher. And yet he appreciated that everyone including himself ordinarily use the verb "to know" all the time. Therefore he concluded that the ordinary meaning of "to know" isn't an insinuation of ideal knowledge. — sime
What I am emphasizing here is what Wittgenstein says in On Certainty in the following:
110 “….As if giving grounds did not come to an end sometime. But the end is not an ungrounded presupposition: it is an ungrounded way of acting.” — Richard B
The "belief" that I have hands does not arise from an inherited background but from the activities of using our hands. Sticking them in my mouth, grasping things, and so on. — Fooloso4
Hinge propositions are regarded as true, but the question of their truth does not usually arise, except for some philosophers or when we can no longer hold to propositions such as, the sun revolves around the earth. — Fooloso4
Why is it that Wittgenstein can have a pass to riff off his own thoughts, but others cannot in relation to Wittgenstein? Odd. Being how ahistorical Wittgenstein was, I would think even the reading of Wittgenstein would invite more caprice than that of a more systemic philosopher. — schopenhauer1
I tend to agree. Of course there is some interpretation involved in what counts as 'serious study' of a subject. it seems to me that most members here autodidacts and hobbyist philosophers. — Tom Storm
If you feel unable or unwilling to have a textual discussion in a textual thread, I don't know what to say! — fdrake
Practicing a religion could gain you divine favor in the afterlife. — Scarecow
