”….not all things are alike, therefore not all things-in-themselves are alike, insofar as for any thing there is that thing-in-itself.”
-Mww
I agree and think this is true if we were speaking about what you can empirically know…. — Bob Ross
Yes, exactly. Knowledge or possible knowledge
a posteriori.
…..but how do you know metaphysically there are things-in-themselves and not a thing-in-itself? — Bob Ross
To know metaphysically is knowledge
a priori, as opposed to empirical knowledge. Knowledge
a priori as it applies to external reality, in Kant, is
impure a priori, insofar as it has empirical conditions contained in the syllogism, and is thereby an inductive inference, a logical function, hence, at least for convenience, is metaphysical knowledge. Which is all the thing-in-itself was ever meant to indicate.
So we don’t
know all things are appearances given from one thing-in-itself, or as many things-in-themselves as there are things that appear. Nevertheless, humans are capable of more than one sensation at a time, either from a single object or from a multiplicity of them. For single objects there’s no conflict, but for more than one sensation from more than one object, and knowledge of things-in-themselves is impossible anyway, we gain nothing by the one-for-all over the each-in-itself, which makes the all-for-one superfluous.
By your own concession, we aren’t supposed to know reality fundamentally is…. — Bob Ross
Not that we’re not supposed to, but that we are not equipped.
By my lights, you cannot be certain that there are things-in-themselves just as much as I can’t be certain that there is a Universal Mind. — Bob Ross
Maybe not, but the alternative is that I am necessary causality for the entire manifold of all that I perceive. Let the contradictions rampant in that scenario simmer awhile.
….if you want to go the truly skeptical route that we are barred from metaphysics (or at least ontology) then to be consistent I think you would have to also rebuke transcendental philosophy — Bob Ross
Absolutely**, but then, I don’t hold with being barred from metaphysical expositions. I just find ontology unnecessary as a discipline in transcendental philosophy, because the existence of things is never in question as is the manifestation of them in experience.
**”…. Thus, the critique of reason leads at last, naturally and necessarily, to science; and, on the other hand, the dogmatical use of reason without criticism leads to groundless assertions, against which others equally specious can always be set, thus ending unavoidably in scepticism….”
This is no different than inferring that the best explanation of what reality fundamentally is is a Universal Mind—there’s no certainty in that either. — Bob Ross
Such is the bane of all speculative metaphysics: there’s no empirical proofs, but only internal logical consistency and strict adherence to the LNC, the only form of certainty we have to guide our contemplations.

First off, appearances are not representations, they are affects on the senses.
-Mww
Appearances are perceptions, which are representations that your mind generated of the sensations. — Bob Ross
Break it down: Appearance = the input to the sensory device; perception = the activity of the sensory device; sensation = the output of the sensory device. The sensory device generates the sensation, which is the matter of the object that appears. Not yet a representation, for the mere matter of sensation has not been arranged into a determinable form. There are representations generated by the mind from sensation, but these are phenomena, in which the matter is arranged into a form by the reproductive imagination.
(Easier to comprehend if it be granted a perception is the reception of the whole object, all at once, which makes descriptive analysis of it impossible, and if the system can’t describe it, can’t analyze it, it won’t be able to cognize it, making knowledge of it impossible)
————
are you saying that the “appearance” is just the impression of the thing-in-itself on you and the representation is the formulation of it according to your mind’s abilities? — Bob Ross
Nope. Impression of the thing.
You are noting that there is an impression, an intuition, and then an understanding of the thing-in-itself…. — Bob Ross
Nope. Impression, intuition, understanding of the thing.
So Kant can’t say stuff like:
“….We have intended, then, to say that all our intuition is nothing but the representation of phenomena; that the things we intuite, are not in themselves the same as our representations of them in intuition….” — Bob Ross
Hey, give him a break. He’s a seriously-genius Enlightenment Prussian. He’s just reminding the readers, maybe half a dozen of whom are his intellectual peers, that the things of intuition are not things-in-themselves. And things-in-themselves, if they contain or are constituted by relations, such must be relations-in-themselves. Continuing with the passage…..
“…..if we take away the subject, or even only the subjective constitution of our senses in general, then not only the nature and relations of objects in space and time, but even space and time themselves disappear….”
The
subjective constitution of our senses in general, which is to say regardless of whatever appears to us, is imagination and the two pure intuitions. Take away imagination the synthesis of matter to form and therefore the phenomenon is impossible; take away the pure intuitions and objects that should have appeared won’t, insofar as there is nothing for object to extend into, therefore they have no shape, and if they have no shape the can contain no matter, and if they contain no matter, they are not objects at all, and if they are not objects at all, there wouldn’t be anything to appear, a blatantly inexcusable contradiction.
If the relations between the phenomena tell us nothing about the things-in-themselves, since they are just the “subjective constitution” of our senses…. — Bob Ross
Phenomena are not what is meant by subjective constitution of our senses in general. Subjective constitution is that within us which makes the transition from sensation, determined by the physiological constitution of the sensory apparatus, to phenomena, possible
The follow-up says it all:
“….. What may be the nature of objects considered as things in themselves and without reference to the receptivity of our sensibility is quite unknown to us…..”
Sensibility is that part of the human cognitive system that has to do with perception, covering the range from appearance to phenomena, technically, “….. The capacity for receiving representations through the mode in which we are affected by objects, is called sensibility….”. The mode in which we are affected means just which one or more of the five sense organs creates its sensation.
Notice, too, that the nature of objects considered as thing-in-themselves, presupposes their existence. I mean….how could the nature of a thing be considered, even if the thing is considered as having the nature of a thing-in-itself, if it didn’t exist? But I think you’ve acceded that point, if I remember right.
—————-
Because this is an extroplation of the relations of phenomena: you are saying that this phenomena relates to another in a manner that suggests they are representations of different things. Kant is barring this (as seen in the above quote). — Bob Ross
I don’t see where in the above quote anything is being barred. If you perceive a horse jumping over a fence as a whole appearance, the phenomenon of the horse is separate from but nonetheless related to the phenomenon of the fence. And this, by the way, is a good example of the intricacies of the system, insofar as motion, having neither matter not form, and therefore not a phenomenon, is provided
a priori as rules by the understanding, re: succession of times in conjunction with a plurality of spaces in a singular intuition.
If you think about it, you can see the validity in it. You may have experience with horses, and with fences, and with things that move, but you’ve never seen a horse jump a fence. But you an still connect a horse to jumping a fence even though you’ve never seen it happen, thus have no experience of it. In short, you can easily conceptually image the motion, a certain indication it must be possible without contradicting the natural order, which is a purely logical deduction, which only understanding can provide, exemplifying the prime dualism in human cognition:
“….. Understanding cannot intuite, and the sensuous faculty cannot think…..”
————-
I think that is what metaphysics is about—giving the best general account of reality. — Bob Ross
Yep, no dispute there at all.
