how we can know if something is unknowable in perpetuity? — Tom Storm
I think, once again, that this can only be a logical claim, which would stand insofar as if something is impossible to know, it will be unknowable for all time. Stuff like....can we know of an effect that has no cause, can we know a conception that does not immediately include its own negation....weird stuff like that, predicated merely on the kind of intellect in play.
On the other hand, and maybe even weirder, is “Rumsfeld’s Ditty”, which implies that of which we don’t know we don’t know, is already unknowable in any time. Technically, though, this reflects on the Kantian category of possibility, which states that a thing must be possible in order to be known, so if there is a thing for which we don’t know the possibility, that is exactly the thing for which there can never be any knowledge.
But still, to think any object is to presuppose its possibility, insofar as it is impossible to think an impossible object. Or, which is the same thing, to think an impossible object is a contradiction. It follows that an unknowable object is an impossible object, but we cannot think an impossible object, so how in the HELL did we ever come up with asking if we can know of something the thought of which can never happen?
Hence, the critique of pure reason. Humans do this kinda stuff all the time, but there's no answers in the doing, or, the answers are in conflict with the questions, rather than satisfying them.
“....Now the transcendental (subjective) reality at least of the pure conceptions of reason rests upon the fact that we are led to such ideas by a necessary procedure of reason. There must therefore be syllogisms which contain no empirical premisses, and by means of which we conclude from something that we do know, to something of which we do not even possess a conception, to which we, nevertheless, by an unavoidable illusion, ascribe objective reality. Such arguments are, as regards their result, rather to be termed sophisms than syllogisms, although indeed, as regards their origin, they are very well entitled to the latter name, inasmuch as they are not fictions or accidental products of reason, but are necessitated by its very nature. They are sophisms, not of men, but of pure reason herself, from which the Wisest cannot free himself. After long labour he may be able to guard against the error, but he can never be thoroughly rid of the illusion which continually mocks and misleads him....”
It’s fun to think about human thinking, but it’s soooooo much more fun, to think about how hay-wire it can go.
