Put the question this way, what determines whether a given object is treated in accordance with sensibility or in accordance with pure speculative reason — Ludwig V
Now there are only two ways in which a necessary agreement of experience with the concepts of its objects can be thought: either the experience makes these concepts possible or these concepts make the experience possible. — CPR B165 to B167 underlined emphasis mine
The conditions of sensible intuition, which bring with them their own distinctions, he [Leibniz] did not regard as original; for sensibility was only a confused kind of representation for him, and not a special source of representations; for him appearance was the representation of the thing in itself, although distinguished from cognition through the understanding in its logical form, since with its customary lack of analysis the former draws a certain mixture of subsidiary representations into the concept of the thing, from which the understanding knows how to abstract. In a word, intellectualized the appearances, just as Locke totally sensitivized the concepts of understanding in accordance with his system of noogony (if I am permitted this expression), i.e., interpreted them as nothing but empirical or abstracted concepts of reflection. Instead of seeking two entirely different sources of representation in the understanding and the sensibility, which could judge about things with objective validity only in conjunction, each of these great men holds on only to one of them, which in his opinion is immediately related to things in themselves, while the other does nothing but confuse or order the representations of the first. — CPR A270/B326
The concept of the noumenon is therefore not the concept of an object, but rather the problem, unavoidably connected with the limitation of our sensibility, of whether there may not be objects entirely exempt from the intuition of our sensibility, a question that can only be given the indeterminate answer that since sensible intuition does not pertain to all things without distinction room remains for more and other objects; they cannot therefore be absolutely denied, but in the absence of a determinate concept (for which no category is serviceable) they also cannot be asserted as objects for our understanding. — ibid B344
On other words, the Critique does teach the twofold aspect, but not of the object. It is the two-fold aspect of the human intellectual system as laid out in transcendental philosophy. It is by means of that system that an object is treated as an appearance in accordance with sensibility on the one hand, or, an object is treated as a ding an sich on the other, in accordance with pure speculative reason. — Mww
We cannot think any object except through categories; we cannot cognize any object that is thought except through intuitions that correspond to those concepts. Now all our intuitions are sensible, and this cognition, so far as its object is given, is empirical. Empirical cognition,
however, is experience. Consequently no a priori cognition is possible for us except solely of objects of possible experience.* But this cognition, which is limited merely to objects of experience, is not on that account all borrowed from experience; rather, with regard to the pure intuitions as well as the pure concepts of the understanding, there are elements of cognition that are to be encountered in us a priori. Now there are only two ways in which a necessary agreement of experience with the concepts of its objects can be thought: either the experience makes these concepts possible or these concepts make the experience possible. The first is not the case with the categories (nor with pure sensible intuition; for they are a priori concepts, hence independent of experience (the assertion of an empirical origin would be a sort of generatio aequivoca [spontaneously generated]. Consequently only the second way remains (as it were a system of the epigenesis48 of pure reason): namely that the categories contain the grounds of the possibility of all experience in general from the side of the understanding. But more about how they make experience possible, and which principles of its possibility they yield in their application to appearances, will be taught in the following chapter on the transcendental use of the power of judgment.
From the footnote at the asterisk:
* So that one may not prematurely take issue with the worrisome and disadvantageous consequences of this proposition, I will only mention that the categories are not restricted in thinking by the conditions of our sensible intuition, but have an unbounded field, and only the cognition of objects that we think, the determination of the object, requires intuition; in the absence of the latter, the thought of the object can still have its true and useful consequences for the use of the subject's reason, which, however, cannot be expounded here, for it is not always directed to the determination of the object, thus to cognition, but rather also to that of the subject and its willing. — CPR B165 to B167 underlined emphasis mine
Understanding is, generally speaking, the faculty of cognitions. These consist in the determinate relation of given representations to an object." An object, however, is that in the concept of which the manifold of a given intuition is united. Now, however, all unification of representations requires unity of consciousness in the synthesis of them. Consequently the unity of consciousness is that which alone constitutes the relation of representations to an object, thus their objective validity, and consequently is that which makes them into cognitions and on which even the possibility of the understanding rests. — CPR B137
The first pure cognition of the understanding, therefore, on which the whole of the rest of its use is grounded, and that is at the same time also entirely independent from all conditions of sensible intuition, is the principle of the original synthetic unity of apperception. Thus the mere form of outer sensible intuition, space, is not yet cognition at all; it only gives the manifold of intuition a priori for a possible cognition. But in order to cognize something in space, e.g., a line, I must draw it, and thus synthetically bring about a determinate combination of the given manifold, so that the unity of this action is at the same time the unity of consciousness (in the concept of a line) and thereby is an object (a determinate space) first cognized. The synthetic unity of consciousness is therefore an objective condition of all cognition, not merely something I myself need in order to cognize an object but rather something under which every intuition must stand in order to become an object for me, since in any other way, and without this synthesis, the manifold would not be united in one consciousness. — ibid. B138 underlined emphasis mine
What may be the case with objects in themselves and abstracted from all this receptivity of our sensibility remains entirely unknown to us. — A42/B59–60
In some sense, human beings experience only appearances, not things in themselves. — ibid
We could strip Berkeley's dictum "To be is to be perceived" of its metaphysical weight about foundations and consider it as just a dictum about existential/social relevance. — Nils Loc
Space and time are big issues in philosophy, and I'm not an expert. But I do agree that we do not experience space as a phenomenon. I wouldn't say that it is a condition for sensibility, but rather a principle of interpretation of the phenomena.
I'm afraid, though, that I simply have no grasp of what he means by saying that it is an intuition. Is it something like a brute fact? — Ludwig V

The transcendental object that grounds both outer appearances and inner intuition is neither matter nor a thinking being in itself, but rather an unknown ground of those appearances that supply us with our empirical concepts of the former as well as the latter. — CPR A379
The principle that throughout dominates and determines my Idealism, is on the contrary: "All cognition of things merely from pure understanding or pure reason is nothing but sheer
illusion, and only in experience is there truth." — Prolegomena to Any Future Metaphysics, page 374, or page 69 in the linked document
The dictum of all genuine idealists from the Eleatic school to Bishop Berkeley, is contained in this formula: "All cognition through the senses and experience is nothing but sheer illusion, and only, in the ideas of the pure understanding and reason there is truth."
The principle that throughout dominates and determines my Idealism, is on the contrary: "All cognition of things merely from pure understanding or pure reason is nothing but sheer
illusion, and only in experience is there truth."
But this is directly contrary to idealism proper. How came I then to use this expression for quite an opposite purpose, and how came my reviewer to see it everywhere?
The solution of this difficulty rests on something that could have been very easily understood from the general bearing of the work, if the reader had only desired to do so. Space and time, together with all that they contain, are not things nor qualities in themselves, but belong merely to the appearances of the latter: up to this point I am one in confession with the above idealists. But these, and amongst them more particularly Berkeley, regarded space as a mere empirical presentation that, like the phenomenon it contains, is only known to us by means of experience or perception, together with its determinations. I, on the contrary, prove in the first place, that space (and also time, which Berkeley did not consider) and all its determinations a priori, can be known by us, because, no less than time, it inheres in our sensibility as a pure form before all perception or experience and makes all intuition of the same, and therefore all its phenomena, possible. It follows from this, that as truth rests on universal and necessary laws as its criteria, experience, according to Berkeley, can have no criteria of truth, because its phenomena (according to him) have nothing a priori at their foundation; whence it follows, that they are nothing but sheer illusion; whereas with us, space and time (in conjunction with the pure conceptions of the understanding) prescribe their law to all possible experience a priori, and at the same time afford the certain criterion for distinguishing truth from illusion therein. — Prolegomena to Any Future Metaphysics, page 374, or page 69 in the linked document
Thinking about this, it seems that Kant's (and Berkeley's) conception of space seems to be that it is something that exists as a vessel or a medium in which objects have their existence. I don't see that. The existence of objects in space and space itself are not two separate discoveries. Each depends on the other, conceptually speaking. — Ludwig V
In the sequel therefore we will understand by a priori cognitions not those that occur independently of this or that experience, but rather those that occur absolutely independently of all experience. Opposed to them are empirical cognitions, or those that are possible only a posteriori, i.e., through experience. Among a priori cognitions, however, those are called pure with which nothing empirical is intermixed. Thus, e.g., the proposition "Every alteration has its cause" is an a priori proposition, only not pure, since alteration is a concept that can be drawn only from experience. — CPR, B2
whereas with us, space and time (in conjunction with the pure conceptions of the understanding) prescribe their law to all possible experience a priori, and at the same time afford the certain criterion for distinguishing truth from illusion therein — ibid.
Idealism (I mean material idealism) is the theory that declares the existence of objects in space outside us to be either merely doubtful and indemonstrable, or else false and impossible; the former is the problematic idealism of Descartes, who declares only one empirical assertion (assertio), namely I am, to be indubitable; the latter is thedogmatic idealism of Berkeley, who declares space, together with all the things to which it is attached as an inseparable condition, to be something that is impossible in itself, and who therefore also declares things in space to be merely imaginary. Dogmatic idealism is unavoidable if
one regards space as a property that is to pertain to the things in themselves; for then it, along with everything for which it serves as a condition, is a non-entity. — CPR B274
The mere, but empirically determined, consciousness of my own existence proves the existence of objects in space outside me — B275
I, represented through inner sense in time, and objects in space outside me, are indeed specifically a wholly distinct appearances, but they are not thereby thought of as different things. The transcendental object that grounds both outer appearances and inner intuition is neither matter nor a thinking being in itself, but rather an unknown ground of those appearances that supply us with our empirical concepts of the former as well as the latter.
If, therefore, as the present critique obviously requires of us, we remain true to the rule established earlier not to press our questions beyond that with which possible experience and its object can supply us, then it will not occur to us to seek information about what the objects of our senses may be in themselves, i.e., apart from any relation to the senses. But if a psychologist takes appearances for things in themselves, then as a materialist he may take up matter into his doctrine, or as a spiritualist he may take up merely thinking beings (namely, according to the form of our inner sense) as the single and sole thing existing in itself, or as a dualist he may take up both; yet through misunderstanding he will always be confined to sophistical reasonings about the way in which that which is no thing in itself, but only the appearance of a thing in general, might exist in itself. — CPR A379
In the sequel therefore we will understand by a priori cognitions not those that occur independently of this or that experience, but rather those that occur absolutely independently of all experience. Opposed to them are empirical cognitions, or those that are possible only a posteriori, i.e., through experience. Among a priori cognitions, however, those are called pure with which nothing empirical is intermixed. Thus, e.g., the proposition "Every alteration has its cause" is an a priori proposition, only not pure, since alteration is a concept that can be drawn only from experience. — CPR, B2
If every human ever is always and only a first-person, doesn’t that make the first-/third-person dichotomy false?, — Mww
The proof that is demanded must therefore establish that we have experience and not merely imagination of outer things, which cannot be accomplished unless one can prove that even our inner experience, undoubted by Descartes, is possible only under the presupposition of outer experience. — CPR, B275
If intuition has to conform
to the constitution of the objects, then I do not see how we can know anything of them a priori — CPR, Bxvi
Hence let us once try whether we do not
get farther with the problems of metaphysics by assuming that the ob-
jects must conform to our cognition, which would agree better with the
requested possibility of an a priori cognition of them, which is to estab
lish something about objects before they are given to us. This would
be just like the first thoughts of Copernicus, who, when he did not
make good progress in the explanation of the celestial motions if he as-
sumed that the entire celestial host revolves around the observer, tried
to see if he might not have greater success if he made the observer re
volve and left the stars at rest. Now in metaphysics we can try in a sim-
ilar way regarding the intuition of objects. If intuition has to conform
to the constitution of the objects, then I do not see how we can know
anything of them a priori; but if the object (as an object of the senses)
conforms to the constitution of our faculty of intuition, then I can very
well represent this possibility to myself. Yet because I cannot stop with
these intuitions, if they are to become cognitions, but must refer them
as representations to something as their object and determine this object
through them, I can assume either that the concepts through which
I bring about this determination also conform to the objects, and then
I am once again in the same difficulty about how I could know anything
about them a priori, or else I assume that the objects, or what is the same
thing, the experience in which alone they can be cognized (as given ob-
jects) conforms to those concepts, in which case I immediately see an
easier way out of the difficulty, since experience itself is a kind of cog-
nition requiring the understanding, whose rule I have to presuppose in
myself before any object is given to me, hence a priori, which rule is ex-
pressed in concepts a priori, to which all objects of experience must
therefore necessarily conform, and with which they must agree. As for
objects insofar as they are thought merely through reason, and neces-
sarily at that, but that (at least as reason thinks them) cannot be given
in experience at all - the attempt to think them (for they must be capa-
ble of being thought) will provide a splendid touchstone of what we as-
sume as the altered method of our way of thinking, namely that we can
cognize of things a priori only what we ourselves have put into them.* — CPR, Bxvi
"Difficult" is a very mild description for this situation. It suggests that you think that "representation" is not really an inappropriate concept to apply here. But you also (seem to) accept that there is no real evidence for such an object "in the unexperienced bush". So I'm rather puzzled what to make of this. — Ludwig V
The synthetic unity of con-
sciousness is therefore an objective condition of all cognition, not
merely something I myself need in order to cognize an object but
rather something under which every intuition must stand in order to
become an object for me, since in any other way, and without this
synthesis, the manifold would not be united in one consciousness. — CPR, B138
The pure concepts of the understanding are free from this limitation
and extend to objects of intuition in general, whether the latter be sim-
ilar to our own or not, as long as it is sensible and not intellectual. But
this further extension of concepts beyond our sensible intuition does
not get us anywhere. For they are then merely empty concepts of ob-
jects, through which we cannot even judge whether the latter are pos-
sible or not - mere forms of thought without objective reality - since
we have available no intuition to which the synthetic unity of apper-
ception, which they alone contain, could be applied, and that could thus
determine an object. Our sensible and empirical intuition alone can
provide them with sense and significance.
Thus if one assumes an object of a non-sensible intuition as given,
one can certainly represent it through all of the predicates that already
lie in the presupposition that nothing belonging to sensible intuition
pertains to it: thus it is not extended, or in space, that its duration is
not a time, that no alteration (sequence of determinations in time) is to
be encountered in it, etc. But it is not yet a genuine cognition if I merely
indicate what the intuition of the object' is not, without being able to
say what is then contained in it; for then I have not represented the pos-
sibility of an object for my pure concept of the understanding at all,
since I cannot give any intuition that would correspond to it, but could
only say that ours is not valid for it. But what is most important here is
that not even a single category could be applied to such a thing, e.g., the
concept of a substance, i.e., that of something that could exist as a sub
ject but never as a mere predicate; for I would not even know whether
there could be anything that corresponded to this determination of
thought if empirical intuition did not give me the case for its applica-
tion. But more of this in the sequel. — ibid. B148
In the transcendental synthesis of the manifold of representations in
general, on the contrary, hence in the synthetic original unity of apper-
ception, I am conscious of myself not as I appear to myself, nor as I am
in myself, but only that I am. This representation is a thinking, not
an intuiting. Now since for the cognition of ourselves, in addition to
the action of thinking that brings the manifold of every possible intu-
ition to the unity of apperception, a determinate sort of intuition,
through which this manifold is given, is also required, my own existence
is not indeed appearance (let alone mere illusion), but the determina-
tion of my existence* can only occur in correspondence with the form
of inner sense, according to the particular way in which the manifold
that I combine is given in inner intuition, and I therefore have no cog-
nition of myself as I am, but only as I appear to myself. The con-
sciousness of oneself is therefore far from being a cognition of oneself,
regardless of all the categories that constitute the thinking of an object
in general through combination of the manifold in an apperception. — ibid. B159
If these representations are false, it may be the case that the person is not actually perceiving objects, despite believing oneself to be perceiving objects. — Metaphysician Undercover
The fact remains, Kant's system *does not work* unless there is an assumption that something causes our sensations. — AmadeusD
It therefore has subjective real-
ity in regard to inner experience, i.e., I really have the representation of
time and of my determinations in it. It is therefore to be regarded re-
ally not as object but as the way of representing myself as object But
if I or another being could intuit myself without this condition of sen-
sibility, then these very determinations, which we now represent to our-
selves as alterations, would yield us a cognition in which the represen-
tation of time and thus also of alteration would not occur at all. Its
empirical reality therefore remains as a condition of all our experiences. — CPR A36/B53

A man can also be an object of love, fear, or admiration even to astonishment and yet not be an object of respect. His jocular humor, his courage and strength, and his power of rank may inspire me with such feelings though inner respect for his is still lacking. Fontanelle says, "I bow to a great man, but my mind does not bow." I can add: to a humble plain man, in whom I perceive righteousness in a higher degree than I am conscious of in myself, my mind bows whether I choose or not, however high I carry my head that he may not forget my superior position. Why? His example holds a law before me which strikes down my self-conceit when I compare my own conduct with it; that it is a law which can be obeyed, and consequently is one that can actually be put into practice is proved to my eyes by the act. — Critique of Practical Reason, translated by Lewis White Beck page 77

The intuition of time is a condition of "all our experiences" therefore it is the essential aspect of the being which is I. — Metaphysician Undercover
Time is certainly something real/
namely the real form of inner intuition. It therefore has subjective real-
ity in regard to inner experience, i.e., I really have the representation of
time and of my determinations in it. It is therefore to be regarded re-
ally not as object but as the way of representing myself as object But
if I or another being could intuit myself without this condition of sen-
sibility, then these very determinations, which we now represent to our-
selves as alterations, would yield us a cognition in which the represen-
tation of time and thus also of alteration would not occur at all. Its
empirical reality therefore remains as a condition of all our experiences.
Only absolute reality cannot be granted to it according to what has been
adduced above. It is nothing except the form of our inner intuition. * If
one removes the special condition of our sensibility from it, then the
concept of time also disappears, and it does not adhere to the objects
themselves, rather merely to the subject that intuits them.
[Kant's footnote at "It is nothing except the form of our inner intuition. * is as follows]
I can, to be sure, say: my representations succeed one another; but that only
means that we are conscious of them as in a temporal sequence, i.e., accord
ing to the form of inner sense. Time is not on that account something in it
self, nor any determination objectively adhering to things.
[Kant's note on the manuscript is as follows]
"Space and time are not merely logical
forms of our sensibility, i.e., they do not consist in the fact that we represent actual re-
lations to ourselves confusedly; for then how could we derive from them a priori syn
thetic and true propositions? We do not intuit space, but in a confused manner; rather
it is the form of our intuition. Sensibility is not confusion of representations, but the
subjective condition of consciousness." — CPR A36/B53
