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
In consequence of the inevitably scattered and fragmentary nature of our thinking, which has been mentioned, and of the mixing together of the most heterogeneous representations thus brought about and inherent even in the noblest human mind, we really possess only *half a consciousness*. With this we grope about in the labyrinth of our life and in the obscurity of our investigations; bright moments illuminate our path like flashes of lighting. But what is to be expected generally from heads of which even the wisest is every night the playground of the strangest and most senseless dreams, and has to take up its meditations again on emerging from these dreams? Obviously a consciousness subject to such great limitations is little fitted to explore and fathom the riddle of the world; and to beings of a higher order, whose intellect did not have time as its form, and whose thinking therefore had true completeness and unity, such an endeavor would necessarily appear strange and pitiable. In fact, it is a wonder that we are not completely confused by the extremely heterogeneous mixture of fragments of representations and of ideas of every kind which are constantly crossing one another in our heads, but that we are always able to find our way again, and to adapt and adjust everything. Obviously there must exist a simple thread on which everything is arranged side by side: but what is this? Memory alone is not enough, since it has essential limitations of which I shall shortly speak; moreover, it is extremely imperfect and treacherous. The *logical ego*, or even the *transcendental synthetic unity of apperception*, are expressions and explanations that will not readily serve to make the matter comprehensible; on the contrary, it will occur to many that“Your wards are deftly wrought, but drive no bolts asunder.”Kant’s proposition: “The *I think* must accompany all our representations ,” is insufficient; for the “I” is an unknown quantity, in other words, it is itself a mystery and a secret. What gives unity and sequence to consciousness, since by pervading all the representations of consciousness, it is its substratum, its permanent supporter, cannot itself be conditioned by consciousness, and therefore cannot be a representation. On the contrary, it must be the *prius* of consciousness, and the root of the tree of which consciousness is the fruit. This, I say, is the *will*; it alone is unalterable and absolutely identical, and has brought forth consciousness for its own ends. It is therefore the will that gives unity and holds all its representations and ideas together, accompanying them, as it were, like a continuous ground-bass. Without it the intellect would have no more unity of consciousness than has a mirror, in which now one thing now another presents itself in succession, or at most only as much as a convex mirror has, whose rays converge at an imaginary point behind its surface. But it is *the will* alone that is permanent and unchangeable in consciousness. It is the will that holds all ideas and representations together as means to its ends, tinges them with the colour of its character, its mood, and its interest, commands the attention, and holds the thread of motives in its hand. The influence of these motives ultimately puts into action memory and the association of ideas. Fundamentally it is the will that is spoken of whenever “I” occurs in a judgement. Therefore, the will is the true and ultimate point of unity of consciousness, and the bond of all its functions and acts. It does not, however, itself belong to the intellect, but is only its root, origin, and controller."—from_The World as Will and Representation_. Translated from the German by E. F. J. Payne in two volumes: volume II, pp. 139-140
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_.

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_.

Metaphysics thinks about beings as beings. Wherever the question is asked what beings are, beings as such are in sight. Metaphysical representation owes this sight to the light of Being. The light itself, i.e., that which such thinking experiences as light, does not come within the range of metaphysical thinking; for metaphysics always represents beings only as beings. Within this perspective, metaphysical thinking does, of course, inquire into the being which is the source and originator of this light. But the light itself is considered sufficiently illuminated as soon as we recognize that we look through it whenever we look at beings.In whatever manner beings are interpreted―whether as spirit, after the fashion of spiritualism; or as becoming and life, or idea, will, substance, subject, or *energeia*; or as the eternal recurrence of the same events―every time, beings as beings appear in the light of Being. Wherever metaphysics represents beings, Being has entered into the light. Being has arrived in a state of unconcealedness (aletheia). But whether and how Being itself involves such unconcealedness, whether and how it manifests itself in, and as, metaphysics, remains obscure. Being in its revelatory essence, i.e., in its truth, is not recalled. Nevertheless, when metaphysics gives answers to its question concerning beings as such, metaphysics speaks out of the unnoticed revealedness of Being. The truth of Being may thus be called the ground in which metaphysics, as the root of the tree of philosophy, is kept and from which it is nourished.Because metaphysics inquires about beings as beings, it remains concerned with beings and does not devote itself to Being as Being. As the root of the tree, it sends all nourishment and all strength into the trunk and its branches. The root branches out in the soil to enable the tree to grow out of the ground and thus to leave it. The tree of philosophy grows out of the soil in which metaphysics is rooted. The ground is the element in which the root of the tree lives, but the growth of the tree is never able to absorb this soil in such a way that it disappears in the tree as part of the tree. Instead, the roots, down to the subtlest tendrils, lose themselves in the soil. The ground is ground for the roots, and in the ground the roots forget themselves for the sake of the tree...Metaphysics, insofar as it always represents only beings as beings, does not recall Being itself. Philosophy does not concentrate on its ground. It always leaves its ground―leaves it by means of metaphysics. And yet, it never escapes its ground...Insofar as a thinker sets out to experience the ground of metaphysics, insofar as the attempts to recall the truth of Being itself instead of merely representing beings as beings, his thinking has in a sense left metaphysics. From the point of view of metaphysics, such thinking goes back into the ground of metaphysics."―from_The Way Back to the Ground of Metaphysics_
