The most perfect and satisfactory knowledge is that of perception but this is limited to the absolutely particular, to the individual. The comprehension of the many and the various into *one* representation is possible only through the *concept*, in other words, by omitting the differences; consequently, the concept is a very imperfect way of representing things. The particular, of course, can also be apprehended immediately as a universal, namely when it is raised to the (Platonic) *Idea*; but in this process, which I have analysed in the third book, the intellect passes beyond the limits of individuality and therefore of time; moreover, this is only an exception.These inner and essential imperfections of the intellect are further increased by a disturbance to some extent external to it but yet inevitable, namely, the influence that the *will* exerts on all its operations, as soon as that will is in any way concerned in their result. Every passion, in fact every inclination or disinclination, tinges the objects of knowledge with its colour. Most common of occurrence is the falsification of knowledge brought about by desire and hope, since they show us the scarcely possible in dazzling colours as probable and well-nigh certain, and render us almost incapable of comprehending what is opposed to it. Fear acts in a similar way; every preconceived opinion, every partiality, and, as I have said, every interest, every emotion, and every predilection of the will act in an analogous manner.Finally, to all these imperfections of the intellect we must also add the fact that it grows old with the brain; in other words, like all physiological functions, it loses its energy in later years; in this way all its imperfections are then greatly increased.”—from_The World as Will and Representation_.

~ Arthur Schopenhauer

To clarify the existentiality of the Self, we take as our ‘natural’ point of departure Dasein’s everyday interpretation of the Self. In *saying* “*I*,” Dasein expresses itself about ‘itself’. It is not necessary that in doing so Dasein should make any utterance. With the ‘I’, this entity has itself in view. The content of this expression is regarded as something utterly simple. In each case, it just stands for me and nothing further. Also, this ‘I’, as something simple, is not an attribute of other Things; it is not *itself* a predicate, but the absolute ‘subject’. What is expressed and what is addressed in saying “I,” is always met as the same persisting something. The characteristics of ‘simplicity’, ‘substantiality’, and ‘personality’, which Kant, for instance, made the basis for his doctrine ‘of the paralogisms of pure reason’, arise from a genuine pre-phenomenological experience. The question remains whether that which we have experienced ontically in this way may be Interpreted ontologically with the help of the ‘categories’ mentioned.Kant, indeed, in strict conformity with the phenomenal content given in saying “I,” shows that the ontical theses about the soul-substance which have been inferred [*erschlossenen*] from these characteristics, are without justification. But in so doing, he merely rejects a wrong *ontical* explanation of the “I”; he has by no means achieved an *ontological* Interpretation of Selfhood, nor has he even obtained some assurance of it and made positive preparation for it. Kant makes a more rigorous attempt than his predecessors to keep hold of the phenomenal content of saying “I”; yet even though in theory he has denied that the ontical foundations of the ontology of the substantial apply to the “I,” he still slips back into *this same* inappropriate ontology. This will be shown more exactly, in order that we may establish what it means ontologically to take saying “I” as the starting point for the analysis of Selfhood. The Kantian analysis of the ‘I think’ is now to be added as an illustration, but only so far as is demanded for clarifying these problems.―from_Being and Time_. Translated by John Macquarrie & Edward Robinson, p. 366

~ Martin Heidegger

The ‘I’ is a bare consciousness, accompanying all concepts. In the ‘I’, ‘nothing more is represented than a transcendental subject of thoughts’. ‘Consciousness in itself (is) not so much a representation…as it is a form of representation in general.’ The ‘I think’ is ‘the form of apperception, which clings to every experience and precedes it.’Kant grasps the phenomenal content of the ‘I’ correctly in the expression ‘I think’, or—if one also pays heed to including the ‘practical person’ when one speaks of ‘intelligence’—in the expression ‘I take action’. In Kant’s sense we must take saying “I” as saying “I think.” Kant tries to establish the phenomenal content of the “I” as *res cogitans*. If in doing so he calls this “I” a ‘logical subject’, that does not mean that the “I” in general is a concept obtained merely by way of logic. The “I” is rather the subject of logical behavior, of binding together. ‘I think’ means ‘I bind together’. All binding together is an ‘*I* bind together’. In any taking-together or relating, the “I” always underlies—the ὑποκείμενον [hypokeimenon; subjectum; subject]. The *subjectum* is therefore ‘consciousness in itself’, not a representation but rather the ‘form’ of representation. That is to say, the “I think” is not something represented, but the formal structure of representing as such, and this formal structure alone makes it possible for anything to have been represented. When we speak of the “form” of representation, we have in view neither a framework nor a universal concept, but that which, as εἶδος [eidos], makes every representing and everything represented be what it is. If the “I” is understood as the form of representation, this amounts to saying that it is the ‘logical subject’.Kant’s analysis has two positive aspects. For one thing, he sees the impossibility of ontically reducing the “I” to a substance; for another thing, he holds fast to the “I” as ‘I think’. Nevertheless, he takes this “I” as subject again, and he does so in a sense which is ontologically inappropriate. For the ontological concept of the subject *characterizes not the Selfhood of the “I” qua Self, but the self-sameness and steadiness of something that is always present-at-hand*. To define the “I” ontologically as “*subject*” means to regard it as something always present-at-hand. The Being of the “I” is understood as the Reality of the *res cogitans*.―from_Being and Time_. Translated by John Macquarrie & Edward Robinson, pp. 366-367

~ Martin Heidegger

But how does it come about that while the ‘I think’ gives Kant a genuine phenomenal starting-point, he cannot exploit it ontologically, and has to fall back on the ‘subject’—that is to say, something *substantial*? The “I” is not just an ‘I think’, but an ‘I think something’. And does not Kant himself keep on stressing that the “I” remains related to its representations, and would be nothing without them?For Kant, however, these representations are the ‘empirical’, which is ‘accompanied’ by the “I”—the appearances to which the “I” ‘clings’. Kant nowhere shows the kind of Being of this ‘clinging’ and ‘accompanying’. At bottom, however, their kind of Being is understood as the constant Being-present-at-hand of the “I” along with its representations. Kant has indeed avoided cutting the “I” adrift from thinking; but he has done so without starting with the ‘I think’ itself in its full essential content as an ‘I think something’, and above all, without seeing what is ontologically ‘presupposed’ in taking the ‘I think something’ as a basic characteristic of the Self. For even the ‘I think something’ is not definite enough ontologically as a starting-point, because the ‘something’ remains indefinite. If by this “something” we understand an entity *within-the-world*, then it tacitly implies that the *world* has been presupposed; and this very phenomenon of the world co-determines the state of Being of the “I,” if indeed it is to be possible for the “I” to be something like an ‘I think something’. In saying “I,” I have in view the entity which in each case I am as an ‘I-am-in-a-world’. Kant did not see the phenomenon of the world, and was consistent enough to keep the ‘representations’ apart from the *a priori* content of the ‘I think’. But as a consequence the “I” was again forced back to an *isolated* subject, accompanying representations in a way which is ontologically quite indefinite.*In saying “I,” Dasein expresses itself as Being-in-the-world*. But does saying “I” in the everyday manner have *itself* in view *as* being-in-the-world [*in-der-Welt-seiend*]? Here we must make a distinction. When saying “I,” Dasein surely has in view the entity which, in every case, it is itself. The everyday interpretation of the Self, however, has a tendency to understand itself in terms of the ‘world’ with which it is concerned. When Dasein has itself in view ontically, it *fails to see* itself in relation to the kind of Being of that entity which it is itself. And this holds especially for the basic state of Dasein, Being-in-the-world.―from_Being and Time_. Translated by John Macquarrie & Edward Robinson, pp. 367-370

~ Martin Heidegger

What is the motive for this ‘fugitive’ way of saying “I”? It is motivated by Dasein’s falling; for as falling, it *flees* in the face of itself into the “they.” When the “I” talks in the ‘natural’ manner, this is performed by the they-self. What expresses itself in the ‘I’ is that Self which, proximally and for the most part, I am *not* authentically. When one is absorbed in the everyday multiplicity and the rapid succession [*Sich-jagen] of that with which one is concerned, the Self of the self-forgetful “I am concerned” shows itself as something simple which is constantly selfsame but indefinite and empty. Yet one *is* that with which one concerns oneself. In the ‘natural’ ontical way in which the “I” talks, the phenomenal content of the Dasein which one has in view in the I gets overlooked; but this gives *no justification for our joining in this overlooking of it*, or for forcing upon the problematic of the Self an inappropriate ‘categorial’ horizon when we Interpret the “I” ontologically.Of course by thus refusing to follow the everyday way in which the “I” talks, our ontological Interpretation of the ‘I’ has by no means *solved* the problem; but it has indeed *prescribed the direction* for any further inquiries. In the “I,” we have in view that entity which one is in ‘being-in-the-world’.Being-already-in-a-world, however, as Being-alongside-the-ready-to-hand-within-the-world, means equiprimordially that one is ahead of oneself. With the ‘I’, what we have in view is that entity for which the *issue* is the Being of the entity that it is. With the ‘I’, care expresses itself, though proximally and for the most part in the ‘fugitive’ way in which the “I” talks when it concerns itself with something. The they-self keeps on saying “I” most loudly and most frequently because at bottom it *is not authentically* itself, and evades its authentic potentiality-for-Being. If the ontological constitution of the Self is not to be traced back either to an “I”-substance or to a ‘subject’, but if, on the contrary, the everyday fugitive way in which we keep on saying “I” must be understood in terms of our *authentic* potentiality-for-Being, then the proposition that the Self is the basis of care and constantly present-at-hand, is one that still does not follow. Selfhood is to be discerned existentially only in one’s authentic potentiality-for-Being-one’s-Self—that is to say, in the authenticity of Dasein’s Being *as care*. In terms of care the *constancy of the Self*, as the supposed persistence of the *subjectum*, gets clarified. But the phenomenon of this authentic potentiality-for-Being also opens our eyes for the *constancy of the Self*, in the double sense of steadiness and steadfastness, is the *authentic* counter-possibility to the non-Self-constancy which is characteristic of irresolute falling. Existentially, “*Self-constancy*” signifies nothing other than anticipatory resoluteness. The ontological structure of such resoluteness reveals the existentiality of the Self’s Selfhood.―from_Being and Time_. Translated by John Macquarrie & Edward Robinson, pp. 368-369

~ Martin Heidegger

Dasein *is authentically itself* in the primordial individualization of the reticent resoluteness which exacts anxiety of itself. *As something that keeps *silent*, authentic *Being*-one’s-Self is just the sort of thing that does not keep on saying ‘I’; but in its reticence it ‘*is*’ that thrown entity as which it can authentically be. The Self which the reticence of resolute existence unveils is the primordial phenomenal basis for the question as to the Being of the ‘I’. Only if we are oriented phenomenally by the meaning of the Being of the authentic potentiality-for-Being-one’s-Self are we put in a position to discuss what ontological justification there is for treating substantiality, simplicity, and personality as characteristics of Selfhood. In the prevalent way of saying “I,” it is constantly suggested that what we have in advance is a Self-Thing, persistently present-at-hand; the ontological question of the Being of the Self must turn away from any such suggestion.*Care does not need to be founded in a Self. But existentiality, as constitutive for care, provides the ontological constitution of Dasein’s Self-constancy, to which there belongs, in accordance with the full structural content of care, its Being-fallen factically into non-Self-constancy*. When fully conceived, the care-structure includes the phenomenon of Selfhood. This phenomenon is clarified by Interpreting the meaning of care; and it is as care that Dasein’s totality of Being has been defined.”―from_Being and Time_. Translated by John Macquarrie & Edward Robinson, pp. 369-370

~ Martin Heidegger

Our conduct of the ontological investigation in the first and second parts opens up for us at the same time a view of the way in which these phenomenological investigations proceed. This raises the question of the character of method in ontology. Thus we come to the third part of the course: the scientific method of ontology and the idea of phenomenology. The method of ontology, that is, of philosophy in general, is distinguished by the fact that ontology has nothing in common with any method of any of the other sciences, all of which as positive sciences deal with beings. On the other hand, it is precisely the analysis of the truth-character of Being which shows that Being also is, as it were, based in a being, namely, in the Dasein. Being is given only if the understanding of Being, hence the Dasein, exists. This being accordingly lays claim to a distinctive priority in ontological inquiry. It makes itself manifest in all discussions of the basic problems of ontology and above all in the fundamental question of the meaning of Being in general. The elaboration of this question and its answer requires a general analytic of the Dasein. Ontology has for its fundamental discipline the analytic of the Dasein. This implies at the same time that ontology cannot be established in a purely ontological manner. Its possibility is referred back to a being, that is, to something ontical―the Dasein. Ontology has an ontical foundation, a fact which is manifest over and over again in the history of philosophy down to the present. For example, it is expressed as early as Aristotle's dictum that the first science, the science of Being, is theology. As the work of the freedom of the human Dasein, the possibilities and destinies of philosophy are bound up with man's existence, and thus with temporality and with historicality, and indeed in a more original sense than is any other science. Consequently, in clarifying the scientific character of ontology, *the first task is the demonstration of its ontical foundation* and the characterisation of this foundation itself.―from_The Basic Problems of Phenomenology_

~ Martin Heidegger

Thus with the question of the Being of truth and the necessity of presupposing it, just as with the question of the essence of knowledge, an 'ideal subject' has generally been posited. The motive for this, whether explicit or tacit, lies in the requirement that philosophy should have the '*a priori*' as its theme, rather than 'empirical facts' as such. There is some justification for this requirement, though it still needs to be grounded ontologically. Yet is this requirement satisfied by positing an 'ideal subject'? Is not such a subject *a fanciful idealization*? With such a conception have we not missed precisely the *a priori* character of that merely 'factual' subject, Dasein? Is it not an attribute of the *a priori* character of the factical subject (that is, an attribute of Dasein's facticity) that it is in the truth and in untruth equiprimordially?The ideas of a 'pure I' and of a 'consciousness in general' are so far from including the *a priori* character of 'actual' subjectivity that the ontological characters of Dasein's facticity and its state of being are either passed over or not seen at all. Rejection of a 'consciousness in general' does not signify that the *a priori* is negated, any more than the positing of an idealized subject guarantees that Dasein has an *a priori* character grounded upon fact.Both the contention that there are 'eternal truths' and the jumbling together of Dasein's phenomenally grounded 'ideality' with an idealized absolute subject, belong to those residues of Christian theology within philosophical problematics which have not as yet been radically extruded.The Being of truth is connected primordially with Dasein. And only because Dasein is as constituted by disclosedness (that is, by understanding), can anything like Being be understood; only so is it possible to understand Being.―from_Being and Time_. Translated by John Macquarrie & Edward Robinson, p. 272

~ Martin Heidegger

Human existence can relate to beings only if it holds itself out into the nothing. Going beyond beings occurs in the essence of Dasein. But this going beyond is metaphysics itself. This implies that metaphysics belongs to the nature of man. It is neither a division of academic philosophy nor a field of arbitrary notions. Metaphysics is the basic occurrence of Dasein. It is Dasein itself. Because the truth of metaphysics dwells in this groundless ground it stands in closest proximity to the constantly lurking possibility of deepest error. For this reason no amount of scientific rigor attains to the seriousness of metaphysics. Philosophy can never be measured by the standard of the idea of science.If the question of the nothing unfolded here has actually questioned us, then we have not simply brought metaphysics before us in an extrinsic manner. Nor have we merely been transposed to it. We cannot be transposed there at all, because insofar as we exist we are always there already. For by nature, my friend, man's mind dwells in philosophy (Plato, Phaedrus, 279a). So long as man exists, philosophizing of some sort occurs. Philosophy―what we call philosophy―is metaphysics getting under way, in which philosophy comes to itself and to its explicit tasks. Philosophy gets under way only by a peculiar insertion of our own existence into the fundamental possibilities of Dasein as a whole. For this insertion it is of decisive importance, first, that we allow space for beings as a whole; second, that we release ourselves into the nothing, which is to say, that we liberate ourselves from those idols everyone has and to which he is wont to go cringing; and finally, that we let the sweep of our suspense take its full course, so that it swings back into the basic question of metaphysics which the nothing itself compels: 'Why are there beings at all, and why not rather nothing?'―from_What is Metaphysics?_

~ Martin Heidegger

Our critique is not opposed to the *dogmatic procedure* of reason in its pure knowledge as science (for science must always be dogmatic, that is, derive its proof from secure *a priori* principles), but only to *dogmatism*, that is, to the presumption that it is possible to make any progress with pure (philosophical) knowledge from concepts according to principles, such as reason has long been in the habit of using, without first inquiring in what way, and by what right, it has come to posses them. Dogmatism is therefore the dogmatic procedure of pure reason, *without a preceding critique of its own powers*; and our opposition to this is not intended to defend that loquacious shallowness which arrogates to itself the name of popularity, much less that skepticism which makes short work of the whole of metaphysics. On the contrary, our critique is meant to form a necessary preparation in support of metaphysics as a thorough science, which must necessarily be carried out dogmatically and strictly systematically, so as to satisfy all the demands, no so much of the public at large, as of the Schools. This is an indispensable demand for it has undertaken to carry out its work entirely *a priori*, and thus to carry it out to the complete satisfaction of speculative reason. In the execution of this plan, as traced out by the critique, that is, in a future system of metaphysics, we shall have to follow the strict method of the celebrated Wolff, the greatest of all dogmatic philosophers. He was the first to give an example (and by his example initiated, in Germany, that spirit of thoroughness which is not yet extinct) of how the secure course of a science could be attained only through the lawful establishment of principles, the clear determination of concepts, the attempt at strictness of proof and avoidance of taking bold leaps in our inferences. He was therefore most eminently qualified to give metaphysics the dignity of a science, if it had only occurred to him to prepare his field in advance by criticism of the organ, that is, of pure reason itself―an omission due not so much to himself as to the dogmatic mentality of his age, about which the philosophers of his own, as well as of all previous times, have no right to reproach one another. Those who reject both the method of Wolff and the procedure of the critique of pure reason can have no other aim but to shake off the fetters of *science* altogether, and thus to change work into play, certainty into opinion and philosophy into philodoxy. ―from_Critique of Pure Reason_.

~ Martin Heidegger

Metaphysics, a completely isolated and speculative branch of rational knowledge which is raised above all teachings of experience and rests on concepts only (not, like mathematics, on their application to intuition), in which reason therefore is meant to be its own pupil, has hitherto not had the good fortune to enter upon the secure path of a science, although it is older than all other sciences, and would survive even if all the rest were swallowed up in the abyss of an all-destroying barbarism. Reason in metaphysics, even if it tries, as it professes, only to gain *a priori* insight into those laws which are confirmed by our most common experience, is constantly being brought to a standstill, and we are obliged again and again to retrace our steps, as they do not lead us where we want to go. As to unanimity among its participants, there is so little of it in metaphysics that it has rather become an arena that would seem especially suited for those who wish to exercise themselves in mock fights, where no combatant has as yet succeeded in gaining even an inch of ground that he could call his permanent possession. There cannot be any doubt, therefore, that the method of metaphysics has hitherto consisted in a mere random groping, and, what is worst of all, in groping among mere concepts.What, then, is the reason that this secure scientific course has not yet been found? Is this, perhaps, impossible? Why, in that case, should nature have afflicted our reason with the restless aspiration to look for it, and have made it one of its most important concerns? What is more, how little should we be justified in trusting our reason, with regard to one of the most important objects of which we desire knowledge, it not only abandons us, but lures us on by delusions, and in the end betrays us! Or, if hitherto we have only failed to meet with the right path, what indications are there to make us hope that, should we renew our search, we shall be more successful than others before us?―from_Critique of Pure Reason_. Preface to the Second Edition. Translated, edited, and with an Introduction by Marcus Weigelt, based on the translation by Max Müller, p. 17

~ Immanuel Kant

A similar experiment may be tried in metaphysics as regards the *intuition* of objects. If the intuition had to conform to the constitution of objects, I would not understand how we could know anything of them *a priori*; but if the object (as object of the senses) conformed to the constitution of our faculty of intuition, I could very well conceive such a possibility. As, however, I cannot rest in these intuitions if they are to become knowledge, but have to refer them as representations, to something as their object, and must determine this object through them, I can assume either that the *concepts* through which I arrive at this determination also conform to the object, and I would again be as perplexed about how I can know anything about it *a priori*; or else that the objects, or what is the same thing, the *experience* in which alone they are known (as objects that are given to us), conform to those concepts. In the latter case, I recognize an easier solution because experience itself is a kind of knowledge that requires understanding; and this understanding has its rules which I must presuppose as existing within me even before objects are given to me, and hence *a priori*. These rules are expressed in *a priori* concepts to which all objects of experience must necessarily conform, and with which they must agree. With regard to objects, insofar as they are thought merely through reason and thought indeed as necessary, and which can never, at least not in the way in which reason thinks them, be given in experience, the attempts at thinking them (for they must admit of being thought) will subsequently furnish an excellent touchstone of what we are adopting as our new method of thought, namely, that we know of things *a priori* only that which we ourselves put into them.―from_Critique of Pure Reason_. Preface to the Second Edition. Translated, edited, and with an Introduction by Marcus Weigelt, based on the translation by Max Müller, pp. 18-19

~ Immanuel Kant

This experiment succeeds as hoped and promises to metaphysics, in its first part, which deals with those *a priori* concepts to which the corresponding objects may be given in experience, the secure course of a science. For by thus changing our point of view, the possibility of *a priori* knowledge can well be explained, and, what is still more, the laws which *a priori* lie at the foundation of nature, as the sum total of the objects of experience, may be supplied with satisfactory proofs, neither of which was possible within the procedure hitherto adopted. But there arises from this deduction of our faculty of knowing *a priori*, as given in the first part of metaphysics, a somewhat startling result, apparently most detrimental to that purpose of metaphysics which has to be treated in its second part, namely the impossibly of using this faculty to transcend the limits of possible experience, which is precisely the most essential concern of the science of metaphysics. But here we have exactly the experiment which, by disproving the opposite, establishes the truth of the first estimate of our *a priori* rational knowledge, namely, that it is directed only at appearances and must leave the thing in itself as real for itself but unknown to us. For that which necessarily impels us to to go beyond the limits of experience and of all appearances is the *unconditioned*, which reason rightfully and necessarily demands, aside from everything conditioned, in all things in themselves, so that the series of conditions be completed. If, then, we find that, under the supposition that our empirical knowledge conforms to objects as things in themselves, the unconditioned *cannot be thought without contradiction*, while under the supposition that our representation of things as they are given to us does not conform to them as things in themselves, but, on the contrary, that these objects as appearance conform to our mode of representation, then *the contradiction vanishes*; and if we find, therefore, that the unconditioned cannot be encountered in things insofar as we are acquainted with them (insofar as they are given to us), but only in things insofar as we are not acquainted with them, that is, insofar as they are things in themselves; then it becomes apparent that what we at first assumed only for the sake of experiment is well founded. However, with speculative reason unable to make progress in the field of the supersensible, it is still open to us to investigate whether in reason's practical knowledge data may not be found which would enable us to determine that transcendent rational concept of the unconditioned, so as to allow us, in accordance with the wish of metaphysics, to get beyond the limits of all possible experience with our *a priori* knowledge, which is possible in practical matters only. Within such a procedure, speculative reason has always at least created a space for such an expansion, even if it has to leave it empty; none the less we are at liberty, indeed we are summoned, to fill it, if we are able to do so, with practical *data* of reason.―from_Critique of Pure Reason_. Preface to the Second Edition. Translated, edited, and with an Introduction by Marcus Weigelt, based on the translation by Max Müller, pp. 19-21

~ Immanuel Kant

The purpose of this critique of pure speculative reason consists in the attempt to change the old procedure of metaphysics, and to bring about a complete revolution after the example set by geometers and investigators of nature. This critique is a treatise on the method, not a system of the science itself; but nevertheless it marks out the whole plan of this science, both with regard to its limits and with regard to its inner organization. For it is peculiar to pure speculative reason that it is able, indeed bound, to measure its own powers according to the different ways in which it chooses its objects for thought, and to enumerate exhaustively the different ways of choosing its problems, thus tracing a complete outline of a system of metaphysics. This is due to the fact that, with regard to the first point, nothing can be attributed to objects in *a priori* knowledge, except what the thinking subject takes from within itself; while, with regard to the second point, pure reason, as far as its principles of knowledge are concerned, forms a separate and independent unity, in which, as in an organized body, every member exists for the sake of all the others, and all the others exist for the sake of the one, so that no principle can be safely applied in *one* relation unless it has been carefully examined in *all* its relations to the whole use of pure reason. Hence, too, metaphysics has this singular advantage, an advantage which cannot be shared by any other rational science which has to deal with objects (for *logic* deals only with the form of thought in general), that if by means of this critique it has been set upon the secure course of a science, it can exhaustively grasp the entire field of knowledge pertaining to it, and can thus finish its work and leave it to posterity as a capital that can never be added to, because it has to deal only with principles and with the limitations of their use, as determined by these principles themselves. And this completeness becomes indeed an obligation if metaphysics is to be a fundamental science, of which we must be able to say, *nil actum reputants, si quid superesset agendum* [to think that nothing was done for as long as something remained to be done]. ―from_Critique of Pure Reason_. Preface to the Second Edition. Translated, edited, and with an Introduction by Marcus Weigelt, based on the translation by Max Müller, pp. 21-22

~ Immanuel Kant

What is gained by the transcendence of the object is the identifiability of the object in a plurality of acts and the identifiability of what is thought by several individuals. This identifiability is not restricted to ideal objects, which are generated according to a definite operational law and are therefore producible by everyone out of the same material of intuition which is given prior to any particular sense-experience. The identifiability obtains in precisely the same way for objects of myth and folklore, of belief and artistic fantasy. Goethe’s Faust, Apollo, and Little Red Riding Hood can be identified by several individuals and are the objects of common, universally valid statements. Indeed, exact identity of the nature of the object in question and evidential knowledge of this identity can occur *only* in the case of ideal objects. Our certainty that we all think the same number 3 in the strictest identity of its nature is much more evident than that we all think the same real object, a tree, for instance. In the case of real objects we can actually prove that it is impossible for the momentary content in which the object is represented and thought to be exactly the same in a plurality of acts and for many individuals. The only other contribution made by the fact of the consciousness of transcendence, so long overlooked in recent philosophy, to the problem of reality is this: the acts in which this consciousness is present can bring the givenness of reality, of which we shall speak later, into “objective” form, and can therefore elevate that which is given in this way as real to the status of a real “object.” But with this, the contribution of the consciousness of transcendence to the problem of reality is at an end.

Hartmann made the same point with respect to Paul Linke’s otherwise shrewd and pertinent comments on his doctrine of reality, still we should emphasize that the transcendence of the object does not *exclude* the reality of the object, not even of the *same* object in the strict sense of “same.” ―from_Idealism and Realism_

There appears to be a fifth way, that of eminence. According to this I argue that it is incompatible with the idea of a most perfect being that anything should excel it in perfection (from the corollary to the fourth conclusion of the third chapter) . Now there is nothing incompatible about a finite thing being excelled in perfection; therefore, etc. The minor is proved from this, that to be infinite is not incompatible with being; but the infinite is greater than any finite being. Another formulation of the same is this. That to which intensive infinity is not repugnant is not all perfect unless it be infinite, for if it is finite, it can be surpassed, since infinity is not repugnant to it. But infinity is not repugnant to being, therefore the most perfect being is infinite.The minor of this proof, which was used in the previous argument, [1] cannot, it seems, be proven *a priori*. For, just as contradictories by their very nature contradict each other and their opposition cannot be made manifest by anything more evident, so also these terms [viz. being and infinite] by their very nature are not repugnant to each other. Neither does there seem to be any way of proving this except by explaining the meaning of the notions themselves. Being cannot be explained by anything better known than itself. Infinite we understand by means of finite. I explain infinite in a popular definition as follows: The infinite is that which exceeds the finite, not exactly by reason of any finite measure, but in excess of any measure that could be assigned.—[2] The following persuasive argument can be given for what we intend to prove. Just as everything is assumed to be possible if its impossibility is not apparent, so also all things are assumed to be compatible if their incompatibility is not manifest. Now there is no incompatibility apparent here, for it is not of the nature of being to be finite; nor does finite appear to be an attribute coextensive with being. But if they were mutually repugnant, it would be for one or the other of these reasons. The coextensive attributes which being possesses seem to be sufficiently evident.—[3] A third persuasive argument is this. Infinite in its own way is not opposed to quantity (that is, where parts are taken successively); therefore, neither is infinity, in its own way, opposed to entity (that is, where perfection exists simultaneously) .—[4] If the quantity characteristic of power is simply more perfect than that characteristic of mass, why is it possible to have an infinity [of parts] in mass and not an infinite power? And if an infinite power is possible, then it actually exists (from the fourth conclusion of the third chapter).—[5] The intellect, whose object is being, finds nothing repugnant about the notion of something infinite. Indeed, the infinite seems to be the most perfect thing we can know. Now if tonal discord so easily displeases the ear, it would be strange if some intellect did not clearly perceive the contradiction between infinite and its first object [viz. being] if such existed. For if the disagreeable becomes offensive as soon as it is perceived, why is it that no intellect naturally shrinks from infinite being as it would from something out of harmony with, and even destructive of, its first object?—from_A Treatise on God as First Principle_, 4.63-4.64

It will be seen how there can be the idea of a special science, the *critique of pure reason* as it may be called. For reason is the faculty which supplies the *principles* of *a priori* knowledge. Pure reason therefore is that which contains the principles of knowing something entirely *a priori*. An *organon* of pure reason would be the sum total of the principles by which all pure *a priori* knowledge can be acquired and actually established. Exhaustive application of such an organon would give us a system of pure reason. But as this would be a difficult task, and as at present it is still doubtful whether indeed an expansion of our knowledge is possible here at all, we may regard a science that merely judges pure reason, its sources and limits, as the *propaedeutic* to the system of pure reason. In general, it would have to be called only a *critique*, not a *doctrine* of pure reason. Its utility, in regard to speculation, would only be negative, for it would serve only to purge rather than to expand our reason, and, which after all is a considerable gain, would guard reason against errors. I call all knowledge *transcendental* which deals not so much with objects as with our manner of knowing objects insofar as this manner is to be possible *a priori*. A system of such concepts would be called *transcendental philosophy*. But this is still, as a beginning, too great an undertaking. For since such a science must contain completely both analytic and synthetic *a priori* knowledge, it is, as far as our present purpose is concerned, much too comprehensive. We will be satisfied to carry the analysis only so far as is indispensably necessary in order to understand in their whole range the principles of *a priori* synthesis, with which alone we are concerned. This investigation, which properly speaking should be called only a transcendental critique but not a doctrine, is all we are dealing with at present. It is not meant to expand our knowledge but only to correct it, and to become the touchstone of the value, or lack of value, of all *a priori* knowledge. Such a critique is therefore the preparation, as far as possible, for a new organon, or, if this should turn out not to be possible, for a canon at least, according to which, thereafter, the complete system of a philosophy of pure reason, whether it serve as an expansion or merely as a limitation of its knowledge, may be carried out both analytically and synthetically. That such a system is possible, indeed that it need not be so comprehensive as to cut us off from the hope of completing it, may already be gathered from the fact that it would have to deal not with the nature of things, which is inexhaustible, but with the understanding which makes judgments about the nature of things, and with this understanding again only as far as its *a priori* knowledge is concerned. The supply of this *a priori* knowledge cannot be hidden from us, as we need not look for it outside the understanding, and we may suppose this supply to prove sufficiently small for us to record completely, judge as to its value or lack of value and appraise correctly. Still less ought we to expect here a critique of books and systems of pure reason, but only the critique of the faculty of pure reason itself. Only once we are in possession of this critique do we have a reliable touchstone for estimating the philosophical value of old and new works on this subject. Otherwise, an unqualified historian and judge does nothing but pass judgments upon the groundless assertions of others by means of his own, which are equally groundless.

~ Immanuel Kant

It is precisely because the principle of the transcendence of the object is completely independent of the existential status of the objects themselves and, thus, independent of the question whether they are produced by us or subsist on their own―whether they are fictions or real beings―that the fact of the consciousness of transcendence is not even remotely qualified to solve the problem of reality. This has been misunderstood equally by W. Freytag, Edith Landmann, P. Linke, and even by Husserl himself. Indeed, people have wanted to speak of an intentional realism (E. Landmann) in contrast to Critical Realism and to all other forms of realism. N. Hartmann was quite correct in emphasizing, in opposition to this, that the projection [*Hinausragen*] of the intentional object beyond the content of consciousness and its act cannot make the least contribution to solving the problem of realism. If something is an intentional object, we cannot recognize from this fact alone, whether it is real or not. If the perceived cherry, the conceived triangle, a friend’s visit anticipated in a dream, Little Red Riding Hood, a freely planned project, or a felt value, have entirely different characteristics and predicates than do the mental processes and the actual contents in which these objects appear, then the distinction between intentional and mental holds equally of both the real and the irreal. *Thus, the problem of what is real is not touched by the fact of the transcendence of the object*, and *percipi est esse*, in Berkeley’s psychologistic sense, is laid to rest. This also frustrates attempts, such as Hume’s in his *Treatise*, to derive being-an-object in general―an object as distinguished from an idea―from a psychogenetic process in which the very ideas through which this psychogenetic process is supposed to be accomplished are themselves reified [*verdinglicht*].―from_Idealism and Realism_

~ Max Scheler

Science and philosophy have for centuries been sustained by unquestioning faith in perception. Perception opens a window on to things. This means that it is directed, quasi-teleologically, towards a *truth in itself* in which the reason underlying all appearances is to be found. The tacit thesis of perception is that at every instant experience can be co-ordinated with that of the previous instant and that of the following, and my perspective with that of other consciousnesses—that all contradictions can be removed, that monadic and intersubjective experience is one unbroken text—that what is now indeterminate for me could become determinate for a more complete knowledge, which is as it were realized in advance in the thing, or rather which is the thing itself. Science has first been merely the sequel or amplification of the process which constitutes perceived things. Just as the thing is the invariant of all sensory fields and of all individual perceptual fields, so the scientific concept is the means of fixing and objectifying phenomena. Science defined a theoretical state of bodies not subject to the action of any force, and *ipso facto* defined force, reconstituting with the aid of these ideal components the processes actually observed. It established statistically the chemical properties of pure bodies, deducing from these those of empirical bodies, and seeming thus to hold the plan of creation or in any case to have found a reason immanent in the world. The notion of geometrical space, indifferent to its contents, that of pure movement which does not by itself affect the properties of the object, provided phenomena with a setting of inert existence in which each event could be related to physical conditions responsible for the changes occurring, and therefore contributed to this freezing of being which appeared to be the task of physics. In thus developing the concept of the thing, scientific knowledge was not aware that it was working on a presupposition. Precisely because perception, in its vital implications and prior to any theoretical thought, is presented as perception of a being, it was not considered necessary for reflection to undertake a genealogy of being, and it was therefore confined to seeking the conditions which make being possible. Even if one took account of the transformations of determinant consciousness, even if it were conceded that the constitution of the object is never completed, there was nothing to add to what science said of it; the natural object remained an ideal unity for us and, in the famous words of Lachelier, a network of general properties. It was no use denying any ontological value to the principles of science and leaving them with only a methodical value, for this reservation made no essential change as far as philosophy was concerned, since the sole conceivable being remained defined by scientific method. The living body, under these circumstances, could not escape the determinations which alone made the object into an object and without which it would have had no place in the system of experience. The value predicates which the reflecting judgment confers upon it had to be sustained, in being, by a foundation of physico-chemical properties. In ordinary experience we find a fittingness and a meaningful relationship between the gesture, the smile and the tone of a speaker. But this reciprocal relationship of expression which presents the human body as the outward manifestation of a certain manner of being-in-the-world, had, for mechanistic physiology, to be resolved into a series of causal relations.”—from_Phenomenology of Perception_.
