work is to express these forms of thought in all their modifications. They are the instrument and the clothing of the forms of thought, and must be accurately adapted to the structure of the latter, so that it may be recognised in them.
(3.) These real, unalterable, original forms of thought are certainly _those of Kant’s logical table of judgments_; only that in this table are to be found blind windows for the sake of symmetry and the table of the categories; these must all be omitted, and also a false arrangement.
Thus:— (_a._) _Quality_: affirmation and negation, _i.e._, combination and separation of concepts: two forms. It depends on the copula.
(_b._) _Quantity_: the subject-concept is taken either in whole or in part: totality or multiplicity. To the first belong also individual subjects: Socrates means “all Socrateses.” Thus two forms. It depends on the subject.
(_c._) _Modality_: has really three forms. It determines the quality as necessary, actual, or contingent. It consequently depends also on the copula.
These three forms of thought spring from the laws of thought of contradiction and identity. But from the principle of sufficient reason and the law of excluded middle springs— (_d._) _Relation._ It only appears if we judge concerning completed judgments, and can only consist in this, that it either asserts the dependence of one judgment upon another (also in the plurality of both), and therefore combines them in the _hypothetical_ proposition; or else asserts that judgments exclude each other, and therefore separates them in the _disjunctive_ proposition. It depends on the copula, which here separates or combines the completed judgments.
The _parts of speech_ and grammatical forms are ways of expressing the three constituent parts of the judgment, the subject, the predicate, and the copula, and also of the possible relations of these; thus of the forms of thought just enumerated, and the fuller determinations and modifications of these. Substantive, adjective, and verb are therefore essential fundamental constituent elements of language in general; therefore they must be found in all languages. Yet it is possible to conceive a language in which adjective and verb would always be fused together, as is sometimes the case in all languages. Provisionally it may be said, for the expression of the _subject_ are intended the substantive, the article, and the pronoun; for the expression of the _predicate_, the adjective, the adverb, and the preposition; for the expression of the _copula_, the verb, which, however, with the exception of the verb to be, also contains the predicate. It is the task of the philosophy of grammar to teach the precise mechanism of the expression of the forms of thought, as it is the task of logic to teach the operations with the forms of thought themselves.
_Note._—As a warning against a false path and to illustrate the above, I which is an utterly abortive attempt to construct the categories out of the grammatical forms. He has entirely confused thought with perception, and therefore, instead of the categories of thought, he has tried to deduce the supposed categories of perception from the grammatical forms, and consequently has placed the grammatical forms in direct relation to perception. He is involved in the great error that _language_ is immediately related to _perception_, instead of being directly related only to thought as such, thus to the _abstract concepts_, and only by means of these to perception, to which they, however, have a relation which introduces an entire change of the form. What exists in perception, thus also the relations which proceed from time and space, certainly becomes an object of thought; thus there must also be forms of speech to express it, yet always merely in the abstract, as concepts. Concepts are always the primary material of thought, and the forms of logic are always related to these, never _directly_ to perception. Perception always determines only the material, never the formal truth of the proposition, for the formal truth is determined according to the logical rules alone.
I return to the Kantian philosophy, and come now to the _Transcendental Dialectic_. Kant opens it with the explanation of _reason_, the faculty which is to play the principal part in it, for hitherto only sensibility and understanding were on the scene. When considering his different explanations of reason, I have already spoken above of the explanation he gives here that “it is the faculty of principles.” It is now taught here that all the _a priori_ knowledge hitherto considered, which makes pure mathematics and pure natural science possible, affords only _rules_, and no _principles_; because it proceeds from perceptions and forms of knowledge, and not from mere conceptions, which is demanded if it is to be called a principle. Such a principle must accordingly be knowledge _from pure conceptions_ and yet _synthetical_. But this is absolutely impossible. From pure conceptions nothing but _analytical_ propositions can ever proceed. If conceptions are to be synthetically and yet _a priori_ combined, this combination must necessarily be accomplished by some third thing, through a pure perception of the formal possibility of experience, just as synthetic judgments _a posteriori_ are brought about through empirical perception; consequently a synthetic proposition _a priori_ can never proceed from pure conceptions. In general, however, we are _a priori_ conscious of nothing more than the principle of sufficient reason in its different forms, and therefore no other synthetic judgments _a priori_ are possible than those which proceed from that which receives its content from that principle.
However, Kant finally comes forward with a pretended principle of the reason answering to his demand, yet only with this _one_, from which others afterwards follow as corollaries. It is the principle which Chr.
Wolf set up and explained in his “_Cosmologia_,” sect. i. c. 2, § 93, and in his “_Ontologia_,” § 178. As now above, under the title of the Amphiboly, mere Leibnitzian philosophemes were taken for natural and necessary aberrations of the reason, and were criticised as such, so here precisely the same thing happens with the philosophemes of Wolf. Kant still presents this principle of the reason in an obscure light, through indistinctness, indefiniteness, and breaking of it up (p. 307; V. 361, and 322; V. 379). Clearly expressed, however, it is as follows: “If the conditioned is given, the totality of its conditions must also be given, and therefore also the _unconditioned_, through which alone that totality becomes complete.” We become most vividly aware of the apparent truth of this proposition if we imagine the conditions and the conditioned as the links of a suspended chain, the upper end of which, however, is not visible, so that it might extend _ad infinitum_; since, however, the chain does not fall, but hangs, there must be above _one_ link which is the first, and in some way is fixed. Or, more briefly: the reason desires to have a point of attachment for the causal chain which reaches back to infinity; it would be convenient for it. But we will examine the proposition, not in figures, but in itself. Synthetic it certainly is; for, analytically, nothing more follows from the conception of the conditioned than that of the condition. It has not, however, _a priori_ truth, nor even _a posteriori_, but it surreptitiously obtains its appearance of truth in a very subtle way, which I must now point out.
Immediately, and _a priori_, we have the knowledge which the principle of sufficient reason in its four forms expresses. From this immediate knowledge all abstract expressions of the principle of sufficient reason are derived, and they are thus indirect; still more, however, is this the case with inferences or corollaries from them. I have already explained above how _abstract_ knowledge often unites a variety of _intuitive_ cognitions in _one_ form or _one_ concept in such a way that they can no longer be distinguished; therefore abstract knowledge stands to intuitive knowledge as the shadow to the real objects, the great multiplicity of which it presents through one outline comprehending them all. Now the pretended principle of the reason makes use of this shadow. In order to deduce from the principle of sufficient reason the unconditioned, which directly contradicts it, it prudently abandons the immediate concrete knowledge of the content of the principle of sufficient reason in its particular forms, and only makes use of abstract concepts which are derived from it, and have value and significance only through it, in order to smuggle its unconditioned somehow or other into the wide sphere of those concepts. Its procedure becomes most distinct when clothed in dialectical form; for example, thus: “If the conditioned exists, its condition must also be given, and indeed all given, thus completely, thus the totality of its conditions; consequently, if they constitute a series, the whole series, consequently also its first beginning, thus the unconditioned.” Here it is false that the conditions of a conditioned can constitute a _series_. Rather must the totality of the conditions of everything conditioned be contained in its _nearest_ ground or reason from which it directly proceeds, and which is only thus a _sufficient_ ground or reason. For example, the different determinations of the state which is the cause, all of which must be present together before the effect can take place. But the series, for example, the chain of causes, arises merely from the fact that we regard what immediately before was the condition as now a conditioned; but then at once the whole operation begins again from the beginning, and the principle of sufficient reason appears anew with its claim. But there can never be for a conditioned a properly successive _series_ of conditions, which exist merely as such, and on account of that which is at last conditioned; it is always an alternating series of conditioneds and conditions; as each link is laid aside the chain is broken, and the claim of the principle of sufficient reason entirely satisfied, it arises anew because the condition becomes the conditioned. Thus the principle of _sufficient_ reason always demands only the completeness of the _immediate or next condition_, never the completeness of a _series_. But just this conception of the completeness of the condition leaves it undetermined whether this completeness should be simultaneous or successive; and since the latter is chosen, the demand now arises for a complete series of conditions following each other. Only through an arbitrary abstraction is a series of causes and effects regarded as a series of causes alone, which exists merely on account of the last effect, and is therefore demanded as its _sufficient_ reason.
From closer and more intelligent consideration, and by rising from the indefinite generality of abstraction to the particular definite reality, it appears, on the contrary, that the demand for a _sufficient_ reason extends only to the completeness of the determinations of the _immediate_ cause, not to the completeness of a series. The demand of the principle of sufficient reason is completely extinguished in each sufficient reason given. It arises, however, immediately anew, because this reason is again regarded as a consequent; but it never demands directly a series of reasons. If, on the other hand, instead of going to the thing itself, we confine ourselves to the abstract concepts, these distinctions vanish.
Then a chain of alternating causes and effects, or of alternating logical reasons and consequents, is given out as simply a chain of causes of the last effect, or reasons of the last consequent, and the _completeness of the conditions_, through which alone a reason becomes _sufficient_, appears as the completeness of that assumed _series_ of reasons alone, which only exist on account of the last consequent. There then appears the abstract principle of the reason very boldly with its demand for the unconditioned. But, in order to recognise the invalidity of this claim, there is no need of a critique of reason by means of antinomies and their solution, but only of a critique of reason understood in my sense, an examination of the relation of abstract knowledge to direct intuitive knowledge, by means of ascending from the indefinite generality of the former to the fixed definiteness of the latter. From such a critique, then, it here appears that the nature of the reason by no means consists in the demand for an unconditioned; for, whenever it proceeds with full deliberation, it must itself find that an unconditioned is an absurdity.
The reason as a faculty of knowledge can always have to do only with objects; but every object for the subject is necessarily and irrevocably subordinated to the principle of sufficient reason, both _a parte ante_ and _a parte post_. The validity of the principle of sufficient reason is so involved in the form of consciousness that we absolutely cannot imagine anything objective of which no _why_ could further be demanded; thus we cannot imagine an absolute absolute, like a blind wall in front of us.
That his convenience should lead this or that person to stop at some point, and assume such an absolute at pleasure, is of no avail against that incontestable certainty _a priori_, even if he should put on an air of great importance in doing so. In fact, the whole talk about the absolute, almost the sole theme of philosophies since Kant, is nothing but the cosmological proof _incognito_. This proof, in consequence of the case brought against it by Kant, deprived of all right and declared outlawed, dare no longer show itself in its true form, and therefore appears in all kinds of disguises—now in distinguished form, concealed under intellectual intuition or pure thought; now as a suspicious vagabond, half begging, half demanding what it wants in more unpretending philosophemes. If an absolute must absolutely be had, then I will give one which is far better fitted to meet all the demands which are made on such a thing than these visionary phantoms; it is matter. It has no beginning, and it is imperishable; thus it is really independent, and _quod per se est et per se concipitur_; from its womb all proceeds, and to it all returns; what more can be desired of an absolute? But to those with whom no critique of reason has succeeded, we should rather say— “Are not ye like unto women, who ever Return to the point from which they set out, Though reason should have been talked by the hour?”
That the return to an unconditioned cause, to a first beginning, by no means lies in the nature of reason, is, moreover, practically proved by the fact that the primitive religions of our race, which even yet have the greatest number of followers upon earth, Brahmanism and Buddhaism, neither know nor admit such assumptions, but carry the series of phenomena conditioning each other into infinity. Upon this point, I refer to the note appended to the criticism of the first antinomy, which occurs further on; and the reader may also see Upham’s “Doctrine of Buddhaism” (p. 9), and in general all genuine accounts of the religions of Asia. Judaism and reason ought not to be identified.
Kant, who by no means desires to maintain his pretended principle of reason as objectively valid, but merely as subjectively necessary, deduces it even as such only by means of a shallow sophism, p. 307; V. 364. He says that because we seek to subsume every truth known to us under a more general truth, as far as this process can be carried, this is nothing else than the pursuit of the unconditioned, which we already presuppose. But, in truth, in this endeavour we do nothing more than apply reason, and intentionally make use of it to simplify our knowledge by enabling us to survey it—reason, which is that faculty of abstract, general knowledge that distinguishes the reflective, thinking man, endowed with speech, from the brute, which is the slave of the present. For the use of reason just consists in this, that we know the particular through the universal, the case through the rule, the rule through the more general rule; thus that we seek the most general points of view. Through such survey or general view our knowledge is so facilitated and perfected that from it arises the great difference between the life of the brutes and that of men, and again between the life of educated and that of uneducated men. Now, certainly the series of _grounds of knowledge_, which exist only in the sphere of the abstract, thus of reason, always finds an end in what is indemonstrable, _i.e._, in an idea which is not further conditioned according to this form of the principle of sufficient reason, thus in the _a priori_ or _a posteriori_ directly perceptible ground of the first proposition of the train of reasoning. I have already shown in the essay on the principle of sufficient reason, § 50, that here the series of grounds of knowledge really passes over into grounds of becoming or of being. But one can only desire to make this circumstance hold good as a proof of an unconditioned according to the law of causality, or even of the mere demand for such an unconditioned, if one has not yet distinguished the forms of the principle of sufficient reason at all, but, holding to the abstract expression, has confounded them all. Kant, however, seeks to establish that confusion, through a mere play upon words, with _Universalitas_ and _Universitas_, p. 322; V. 379. Thus it is fundamentally false that our search for higher grounds of knowledge, more general truths, springs from the presupposition of an object unconditioned in its being, or has anything whatever in common with this. Moreover, how should it be essential to the reason to presuppose something which it must know to be an absurdity as soon as it reflects? The source of that conception of the unconditioned is rather to be found only in the indolence of the individual who wishes by means of it to get rid of all further questions, whether his own or of others, though entirely without justification.
Now Kant himself denies objective validity to this pretended principle of reason; he gives it, however, as a necessary subjective assumption, and thus introduces an irremediable split into our knowledge, which he soon allows to appear more clearly. With this purpose he unfolds that principle of reason further, p. 322; V. 379, in accordance with the method of architectonic symmetry of which he is so fond. From the three categories of relation spring three kinds of syllogisms, each of which gives the clue for the discovery of a special unconditioned, of which again there are three: the soul, the world (as an object in itself and absolute totality), and God. Now here we must at once note a great contradiction, of which Kant, however, takes no notice, because it would be very dangerous to the symmetry. Two of these unconditioneds are themselves conditioned by the third, the soul and the world by God, who is the cause of their existence.
Thus the two former have by no means the predicate of unconditionedness in common with the latter, though this is really the point here, but only that of inferred being according to the principles of experience, beyond the sphere of the possibility of experience.
Setting this aside, we recognise in the three unconditioneds, to which, according to Kant, reason, following its essential laws, must come, the three principal subjects round which the whole of philosophy under the influence of Christianity, from the Scholastics down to Christian Wolf, has turned. Accessible and familiar as these conceptions have become through all these philosophers, and now also through the philosophers of pure reason, this by no means shows that, without revelation, they would necessarily have proceeded from the development of all reason as a production peculiar to its very nature. In order to prove this it would be necessary to call in the aid of historical criticism, and to examine whether the ancient and non-European nations, especially the peoples of Hindostan and many of the oldest Greek philosophers, really attained to those conceptions, or whether it is only we who, by quite falsely translating the Brahma of the Hindus and the Tien of the Chinese as “God,” good-naturedly attribute such conceptions to them, just as the Greeks recognised their gods everywhere; whether it is not rather the case that theism proper is only to be found in the religion of the Jews, and in the two religions which have proceeded from it, whose followers just on this account comprise the adherents of all other religions on earth under the name of heathen, which, by the way, is a most absurd and crude expression, and ought to be banished at least from the writings of the learned, because it identifies and jumbles together Brahmanists, Buddhists, Egyptians, Greeks, Romans, Germans, Gauls, Iroquois, Patagonians, Caribbeans, Otaheiteans, Australians, and many others. Such an expression is all very well for priests, but in the learned world it must at once be shown the door: it can go to England and take up its abode at Oxford. It is a thoroughly established fact that Buddhism, the religion which numbers more followers than any other on earth, contains absolutely no theism, indeed rejects it. As regards Plato, it is my opinion that he owes to the Jews the theism with which he is periodically seized. On this account Numenius (according to Clem. Alex., _Strom._, i. c. 22, Euseb. _præp.
evang._, xiii. 12, and Suidas under Numenius) called him the _Moses græcisans_: Τι γαρ εστι Πλατων, η Μωσης αττικιζων; and he accuses him of having stolen (αποσυλησας) his doctrine of God and the creation from the Mosaical writings. Clemens often repeats that Plato knew and made use of 10, and iii. 11; also in the _Cohortatio ad gentes_, c. 6, where, after he has bitterly censured and derided the whole of the Greek philosophers in the preceding chapter because they were not Jews, he bestows on Plato nothing but praise, and breaks out into pure exultation that as Plato had learnt his geometry from the Egyptians, his astronomy from the Babylonians, magic from the Thracians, and much also from the Assyrians, so he had learnt his theism from the Jews: Οιδα σου τους διδασκαλους, καν αποκρυπτειν εθελῇς,...δοξαν την του θεου παρ᾽ αυτων ωφελησει των Εβραιων (_Tuos magistros novi, licet eos celare velis,...illa de Deo sententia suppeditata tibi est ab Hebræis_). A pathetic scene of recognition. But I see a remarkable confirmation of the matter in what follows. According to Plutarch (_in Mario_), and, better, according to Lactantius (i. 3, 19), Plato thanked Nature that he had been born a human being and not a brute, a man and not a woman, a Greek and not a barbarian. Now in Isaac Euchel’s “Prayers of the Jews,” from the Hebrew, second edition, 1799, p. 7, there is a morning prayer in which God is thanked and praised that the worshipper was born a Jew and not a heathen, a free man and not a slave, a man and not a woman. Such an historical investigation would have spared Kant an unfortunate necessity in which he now becomes involved, in that he makes these three conceptions spring necessarily from the nature of reason, and yet explains that they are untenable and unverifiable by the reason, and thus makes the reason itself a sophisticator; for he says, p.
339; V. 397: “There are sophistications, not of man, but of pure reason itself, from which even the wisest cannot free himself, and although after much trouble he may be able to avoid error, yet he never can escape from the illusion which unceasingly torments and mocks him.” Therefore these Kantian “Ideas of the Reason” might be compared to the focus in which the converging reflected rays from a concave mirror meet several inches before its surface, in consequence of which, by an inevitable process of the understanding, an object presents itself to us there which is a thing without reality.
But the name “Idea” is very unfortunately chosen for these pretended necessary productions of the pure theoretical reason, and violently appropriated from Plato, who used it to denote the eternal forms which, multiplied through space and time, become partially visible in the innumerable individual fleeting things. Plato’s “Ideas” are accordingly throughout perceptible, as indeed the word which he chose so definitely signifies, for it could only be adequately translated by means of perceptible or visible things; and Kant has appropriated it to denote that which lies so far from all possibility of perception that even abstract thought can only half attain to it. The word “Idea,” which Plato first introduced, has, moreover, since then, through two-and-twenty centuries, always retained the significance in which he used it; for not only all ancient philosophers, but also all the Scholastics, and indeed the Church Fathers and the theologians of the Middle Ages, used it only in that Platonic sense, the sense of the Latin word _exemplar_, as Suarez expressly mentions in his twenty-fifth Disputation, sect. 1. That Englishmen and Frenchmen were later induced by the poverty of their languages to misuse this word is bad enough, but not of importance. Kant’s misuse of the word idea, by the substitution of a new significance introduced by means of the slender clue of not being object of experience, which it has in common with Plato’s ideas, but also in common with every possible chimera, is thus altogether unjustifiable. Now, since the misuse of a few years is not to be considered against the authority of many centuries, I have always used the word in its old, original, Platonic significance.
The refutation of _rational psychology_ is much fuller and more thorough in the first edition of the “Critique of Pure Reason” than in the second and following editions, and therefore upon this point we must make use of the first edition exclusively. This refutation has as a whole very great merit and much truth. Yet I am clearly of the opinion that it was merely from his love of symmetry that Kant deduced as necessary the conception of the soul from the paralogism of substantiality by applying the demand for the unconditioned to the conception _substance_, which is the first category of relation, and accordingly maintained that the conception of a soul arose in this way in every speculative reason. If this conception really had its origin in the presupposition of a final subject of all predicates of a thing, one would have assumed a soul not in men alone, but also just as necessarily in every lifeless thing, for such a thing also requires a final subject of all its predicates. Speaking generally, however, Kant makes use of a quite inadmissible expression when he talks of something which can exist only as subject and not as predicate (_e.g._, Critique of Pure Reason, p. 323; V. 412; Prolegomena, § 4 and 47); though a precedent for this is to be found in Aristotle’s “Metaphysics,” iv. ch.
8. Nothing whatever exists as subject and predicate, for these expressions belong exclusively to logic, and denote the relations of abstract conceptions to each other. Now their correlative or representative in the world of perception must be substance and accident. But then we need not look further for that which exists always as substance and never as accident, but have it directly in matter. It is the substance corresponding to all properties of things which are their accidents. It is, in fact, if one wishes to retain the expression of Kant which has just been condemned, the final subject of all predicates of that empirically given thing, that which remains after the abstraction of all its properties of every kind. And this holds good of man as of a brute, a plant, or a stone, and is so evident, that in order not to see it a determined desire not to see is required. That it is really the prototype of the conception substance, I will show soon. But subject and predicate are related to substance and accident rather as the principle of sufficient reason in logic to the law of causality in nature, and the substitution or identification of the former is just as inadmissible as that of the latter. Yet in the “Prolegomena,” § 46, Kant carries this substitution and identification to its fullest extent in order to make the conception of the soul arise from that of the final subject of all predicates and from the form of the categorical syllogism. In order to discover the sophistical nature of this paragraph, one only needs to reflect that subject and predicate are purely logical determinations, which concern abstract conceptions solely and alone, and that according to their relation in the judgment. Substance and accident, on the other hand, belong to the world of perception and its apprehension in the understanding, and are even there only as identical with matter and form or quality. Of this more shortly.
The antithesis which has given occasion for the assumption of two fundamentally different substances, body and soul, is in truth that of objective and subjective. If a man apprehends himself objectively in external perception, he finds a being extended in space and in general merely corporeal; but if, on the other hand, he apprehends himself in mere self-consciousness, thus purely subjectively, he finds himself a merely willing and perceiving being, free from all forms of perception, thus also without a single one of the properties which belong to bodies. Now he forms the conception of the soul, like all the transcendental conceptions called by Kant Ideas, by applying the principle of sufficient reason, the form of all objects, to that which is not an object, and in this case indeed to the subject of knowing and willing. He treats, in fact, knowing, thinking, and willing as effects of which he seeks the cause, and as he cannot accept the body as their cause, he assumes a cause of them entirely different from the body. In this manner the first and the last of the dogmatists proves the existence of the soul: Plato in the “Phædrus” and also Wolf: from thinking and willing as the effects which lead to that cause. Only after in this way, by hypostatising a cause corresponding to the effect, the conception of an immaterial, simple, indestructible being had arisen, the school developed and demonstrated this from the conception of _substance_. But this conception itself they had previously constructed specially for this purpose by the following artifice, which is worthy of notice.
With the first class of ideas, _i.e._, the real world of perception, the idea of matter is also given; because the law governing this class of ideas, the law of causality, determines the change of the states or conditions, and these conditions themselves presuppose something permanent, whose changes they are. When speaking above of the principle of the permanence of substance, I showed, by reference to earlier passages, that this idea of matter arises because in the understanding, for which alone it exists, time and space are intimately united, and the share of space in this product exhibits itself as the permanence of matter, while the share of time appears as the change of states. Purely in itself, matter can only be thought _in abstracto_, and not perceived; for to perception it always appears already in form and quality. From this conception of _matter_, _substance_ is again an abstraction, consequently a higher _genus_, and arose in this way. Of the conception of matter, only the predicate of permanence was allowed to remain, while all its other essential properties, extension, impenetrability, divisibility, &c., were thought away. Like every higher _genus_, then, the concept _substance_ contains _less in itself_ than the concept _matter_, but, unlike every other higher _genus_, it does not contain _more under it_, because it does not include several lower _genera_ besides matter; but this remains the one true species of the concept substance, the only assignable thing by which its content is realised and receives a proof. Thus the aim with which in other cases the reason produces by abstraction a higher conception, in order that in it several subordinate species may be thought at once through common determinations, has here no place; consequently that abstraction is either undertaken idly and entirely without aim, or it has a secret secondary purpose. This secret purpose is now brought to light; for under the conception substance, along with its true sub-species matter, a second species is co-ordinated—the immaterial, simple, indestructible substance, soul. But the surreptitious introduction of this last concept arose from the fact that the higher concept _substance_ was framed illogically, and in a manner contrary to law. In its legitimate procedure the reason always frames the concept of a higher genus by placing together the concepts of several species, and now comparing them, proceeds discursively, and by omitting their differences and retaining the qualities in which they agree, obtains the generic concept which includes them all but has a smaller content. From this it follows that the concepts of the species must always precede the concept of the genus. But, in the present case, the converse is true. Only the concept matter existed before the generic concept _substance_. The latter was without occasion, and consequently without justification, as it were aimlessly framed from the former by the arbitrary omission of all its determinations except one. Not till afterwards was the second ungenuine species placed beside the concept matter, and so foisted in. But for the framing of this second concept nothing more was now required than an express denial of what had already been tacitly omitted in the higher generic concept, extension, impenetrability, and divisibility. Thus the concept _substance_ was framed merely to be the vehicle for the surreptitious introduction of the concept of the immaterial substance. Consequently, it is very far from being capable of holding good as a category or necessary function of the
