What I’m thinking of, here, is the person who says that “observation” or “measurement” is sufficient for knowledge, but “intuition” is not. From this, they say that only things that can (in principle, at least) be measured or inferred from measurement can be said to exist. Of course, observation and measurement [and inferences from these] are forms of intuition; this is much like saying that textbooks are a good educational tools, but books are not. You can make a distinction, I suppose, but how is it not arbitrary?
Okay, so you’re thinking of a person who is just confused about their own practice, not someone who actually excludes intuitions from their ontology somehow?
I think there is a powerful difference between the two, but I’m still wrapping my mind around it. Certainly the direction you said is true, but I don’t think it’s quite as fundamental. “Our ideas about the world conform to the world” is Hume’s issue – they ought to conform to the world, because all our ideas come from the world. And yet there are insuperable problems even here, the problems of induction.
Insuperable problems? I wonder if that’s true. I tend to think Hume discovers big problems with induction because he has a naive and artificial view about what induction is.
But “all our ideas come from the world” is clearly incomplete; for our existence is a historical fact, and “what kind of being we are” obviously sets parameters for our ability to think. One such parameter is that we cannot comprehend what it would mean for something not to be itself. Is that evidence of its truth? I think we will all agree that it is a necessary assumption, but it is based on the structure of the mind, not on anything we can objectively evaluate.
It depends what is meant by world here. World, as I conceive of it, is something that is intrinsically related to our historical being. Speaking of an abstract world apart from the historical situation of some beings or other who possess some form or other of world-historical consciousness is not really intelligible. Berkeley’s
esse est percipi has a great deal more truth in it than its “common sense” refuters would like to admit.
Since we’re quoting Wittgenstein, how’s this: “The facts in logical space are the world.” The empiricist begins by saying that these all facts are somehow about the physical reality, which (I would claim) is a *subset *of the world.
But not all empiricists are physicalists, right?
Well, this is a deeper question. **If **our understanding of the world can be justified, it must be through intuition. But can it be justified?
If we do justify it, then it can be justified. But the question then just shifts to one about what justification is. But this is just a question about seeing correctly what our practice of justification consists of; and it would be silly to further try to
justify that
this should count as a justification. We have to defer to sth like a Lebensform. A form of life can only be pointed to - if someone refuses to look and to see (or to
come and see, in the words of our Lord), and instead insists that we justify our basic practices, or arbitrarily pretends that he
can justify some, while arbitrarily refusing to apply the same procedure of ‘justification’ to others, he is choosing to blind himself to the (‘objective’) nature of (‘subjective’) reality.
Interesting. I agree with the idea that epistemology is essentially involved in rationalization of behavior after the fact. I find it very interesting that Wittgenstein says that we are justified in the practice of a belief – this is how we do x – but not in its content. If he is wrong, I can only take it to be that epistemology is a discipline without a foundation (in order to make any sense, it must first deal with the metaphysical issue of connecting mind and world**).
Only if it was already burdened with that issue to begin with. But if it was, then it was never just epistemology. And in fact, that is correct: epistemology is never just epistemology, it is always also metaphysics, and vice versa. (People who dismiss metaphysics in favor of epistemology are simply confused about what they’re doing.)
If he is right, however, then all (honest) epistemological claims seem to be true, but trivial. “I know there is a table here” simply means that I act as if this phenomenon is a table; the action justifies the belief.
I think I would want to say that the action is the
substance of the belief, but that the belief is not one of those for which reasonable (sane) people offer justifications. And I would want to emphasize that action and behavior includes linguistic acts and behaviors. So I wouldn’t want to say that the (conceptual/linguistic) content of a belief is
not justified, since it is somehow
not ‘the practice of a belief.’
So is epistemology utterly unjustified or just trivial?
Epistemology is as epistemology does.
