(3) Viewing space and time, which condition external relation, as merely confused forms of apprehension, Leibniz further concluded that the reality of substance is purely internal. And ruling out position, shape, contact and motion, all of which involve external relations, he felt justified in endowing the monads with the sole remaining form of known existence, namely consciousness. The assertion that the monads are incapable of external relation leads to the further conclusion that they are incapable of interaction, and stand in systematic relation to one another, solely in virtue of a pre-established harmony.
(4) From the point of view of pure thought matter must precede form. The universal must precede the particular which is a specification of it.[1330] Unlimited reality is taken as being the matter of all possibility, and its limitation or form as being due to negation. Substances must antecedently exist in order that external relations may have something upon which to ground themselves. Space and time must be interpreted as confused apprehensions of purely intellectual orders, space representing a certain order in the reciprocal (pre-established) correspondence of substances, and time the dynamical sequence of their states. On the other hand, from the standpoint of sense and its intuitional forms the reverse holds. The world of appearance is conditioned by the forms of space and time; the objectively possible coincides with the actual; and the substantia phaenomenon has no independent essence, but reduces without remainder to external relations. For pure thought this world of given appearance is an utterly paradoxical form of existence; it is the direct opposite of everything that genuine reality ought to be. In this strange conclusion the problems of the Dialectic, in one of their most suggestive forms, at once loom up before us. As stated above, this entire discussion is an anticipation of questions which cannot be adequately treated within the limits of the Analytic.
The text of this section is highly composite. The entire content of the Appendix is twice reintroduced and restated at full length in the accompanying Note. These successive expositions of one and the same argument were doubtless independently written, and then later pieced together in this external fashion. A 277-8 = B 333-4, on the nature of the substantia phaenomenon, would by its references to the transcendental object seem to be of early origin.[1331] It has already been commented upon.[1332] A 285-9 = B 342-6, on the other hand, which supplements the chapter on Phenomena and Noumena,[1333] would seem to be of late origin. It is so dated by Adickes,[1334] owing to the reference to schemata in its opening sentence.
A 289-91 = B 346-9. Table of the division of the conception of nothing.—This curious and ingenious classification of the various meanings of the term ‘nothing’ is chiefly of interest through its first division: “empty conception without object, ens rationis.” The ens rationis can best be defined in its distinction from the fourth division: “empty object without conception, nihil negativum.” The former is a Gedankending; the latter is an Unding. The former indeed, though not contradictory, is mere fiction (bloss Erdichtung), and consequently must not be taken as falling within the field of the possible. The latter is a concept which destroys itself, and which therefore stands in direct conflict with the possible. The ens rationis includes, Kant explicitly states,[1335] the conception of noumena, “which must not be reckoned among the possibilities, although they must not for that reason be declared to be also impossible.” Kant must here be taking noumena in the positive sense.[1336] As usual Kant’s attempt to obtain parallels for the four classes of category breaks down. The so-called nihil privativum and the ens imaginarium do not properly come within the denotation of the term ‘nothing.’ This is very evident in the examples which Kant cites. Cold is as real as the opposite with which it is contrasted, while pure space and pure time are not negative even in a conventional sense.
TRANSCENDENTAL LOGIC

THE TRANSCENDENTAL DIALECTIC
INTRODUCTORY COMMENT UPON THE COMPOSITE ORIGIN AND CONFLICTING TENDENCIES OF THE DIALECTIC.
We have had constant occasion to observe the composite origin and conflicting tendencies of the Analytic. The Dialectic is hardly less composite in character, and is certainly not more uniform in its fundamental teaching.
The composite nature of the text, though bewildering to the unsophisticated reader, is not, however, without its compensations. The text, as it stands, preserves the record of the manifold influences which presided over its first inception, and of the devious paths by which Kant travelled to his later conclusions. It thus enables us to determine, with considerable accuracy, the successive stages through which it has passed in the process of settling into its present form. As we shall find, the sections on the antinomies contain the original argument, out of which by varied processes of supplementation and modification the other parts have arisen.
The conflict of doctrine has also its counter-advantages. The problems are impartially discussed from opposed standpoints; the difficulties peculiar to each of the competing possible solutions are frankly recognised, and indeed insisted upon; and the internal dialectic of Kant’s own personal thinking obtains dramatic expression. We are thus the better enabled to appreciate the open-minded pertinacity with which Kant set himself to do justice to every significant aspect of his many-sided problems, and are consequently in less danger of simplifying his argument in any arbitrary manner, or of ignoring the tentative character of the solutions at which he arrives.
I shall first define the main lines of conflict, and shall then attempt to trace those conflicts to the considerations in which they have their source. The two chief lines of thought traceable throughout the Dialectic are represented by its negative and by its positive tendencies respectively. From one point of view, Reason is merely the understanding in its self-limiting, self-regulative employment, and the main purpose of the Dialectic is to guard against the delusive power of fictitious principles. From the other point of view, Reason is a faculty distinct from understanding, and its problems run parallel with those of the Analytic, forming no less important a subject of philosophical reflection, and no less fruitful a source of positive teaching. The one line of argument connects with Kant’s more sceptical tendencies, the other with his deep-rooted belief in the ultimate validity of the absolute claims of pure thought.
When we approach the Dialectic from the standpoint of the Analytic, it is the negative aspect that is naturally most prominent. In the Analytic Kant has proved that all knowledge is limited to sense-experience, and that a metaphysical interpretation of reality is altogether impossible. But as the human mind would seem to be possessed by an inborn need of metaphysical construction, this conclusion cannot obtain its due influence until the sources of the metaphysical tendency have been detected and laid bare. The Dialectic must yield a psychology of metaphysics as well as a logic of illusion.
