moreThe original project of Kant's philosophy, as given in the Monadologia Physica of 1756, consists in establishing a metaphysica cum geometria iuncta. This project requires a foundation of both form and matter of knowledge. To access the origin of form and matter, Kant must find a new methodology, different from the procedure of classical metaphysics. This methodology is first shown in 1764, when Kant states that metaphysics must proceed according to the data of inner sense. However, inner sense does not express a merely passive faculty, but shows a certain activity in the demarcation of outer space, which ultimately proceeds from self-affection. Kant's new methodology then discovers that human reason projects the form of knowledge (space and time) on the basis of formal self-affection. This procedure contains the specific stamp of the transcendental model of reason as opposed to empiricism and rationalism, and constitutes the "hidden art" of the epigenesis of pure reason in the KrV (B 167). The momentum proper to epigenesis is, then, self-affection.
Many commentators have researched the movement of self-affection without having an adequate methodology. On the one hand, self-affection is discovered in inner sense. On the other hand, self-affection refers to an act of our spontaneity to affect the form of inner sense. In order for there not to be a causal connection between the empirical and the transcendental that would shatter the Kantian theory of subjectivity, we must conceive the movement of self-affection within a strictly transcendental sphere: neither self-affection can be the cause of empirical self-consciousness (such as attention), nor empirical representations can cause self-affection. The movement of formal self-affection consists of the following: the empirical affection, taken transcendental as an occasional cause (Gelegenheitsursache, KrV, A 86), offers the transcendental subject the epigenetic input for the demarcation of reality in his description of the sensible space, thus obtaining the geometric representation of space-time. For this reason, inner sense does not constitute an effect of self-affection, but only an example of what happens in our geometric-formal configuration of experience when we describe space, putting at the same time attention in the description act, and not in what is described.
Unfortunately, this methodology, better known as double aspect view, or two aspects view, has been applied by commentators only to the problem of the thing in itself and the affection. In that context, it is clear that the thing in itself that affects our senses only possesses an empirical condition. On the other hand, a transcendental thing in itself cannot affect our empirical sensibility. Nevertheless, the double aspect view also allows to conceive transcendental causes, in so far as its effects are understood from a transcendental perspective as well. For this reason, G. Prauss has pointed out that transcendental philosophy is a non-empirical science of the empirical. Despite this, none of the commentators have been able to give an immanent explanation to the passages of the Transcendental Dialectics where Kant refers to the transcendental object as ground of appearances (Grund der Erscheinungen). To explain this meaning of the transcendental object, it is necessary to resort to the Kantian concept of transcendental matter (transzendentale Materie, KrV, A 143), which fulfills diverse functions in the KrV, and serves as an epistemological imperative to explain the material-transcendental origin of our appearances. In this way, the transcendental object as ground of appearances, and the transcendental affection that it implies, does not mean more than a material-transcendental underside of empirical affection, where what is explained is not so much the passivity of our empirical sensibility, but the finitude of our transcendental sensibility. Our concept of transcendental-material object implicitly infiltrates almost all the Principles of Understanding, under different names: The Anticipations of Perception do not make sense without referring to a transcendental matter, so that this announces a dynamic condition in its differential relationship with the Anticipations of Perception. At the same time, the Analogies of Experience also reproduce the empirical-transcendental duality in relation to matter: from the corporal substance Kant moves himself towards a transcendental substratum, from causality towards force in general, and from the reciprocal action of substances towards the continuous influx of matter. Finally, the problem of judgements of experience also shows us the necessity to conceive a transcendental-material object that constitutes the true object of knowledge in physics. For this reason J. Vuillemin points out that “le jugement d’expérience [est] la projection transcendentale de cette intensité dans l’objet = X.” (J. Vuillemin, Physique et Métaphysique Kantiennes, p. 139) In this sense, the transcendental-material object not only assumes an intensive, but also a constitutive-regulative complexion in our scientific research of matter (Anticipation quoad materiale). All the difficulties that we have mentioned from the problem of the thing in itself, offer a still moving ground, but that prepares the way towards an overall solution in the idea of ether and epigenesis of matter.
The transcendental origin of the idea of ether is found in the chapter on the Transcendental Ideal, in the KrV. This concept has both a metaphysical and a practical function in the empirical use of reason. On the one hand, it is an omnitudo realitatis that serves as a principle of individuation of matter. On the other hand, it is an ideal with practical-regulative force, capable of leading our empirical investigation of matter. This is the most concrete antecedent of a transcendental ideal of ether that we possess in the KrV. However, the ideal of ether is disrupted by an amphiboly running through the whole Kantian doctrine of matter until the year 1799. In his Opus postumum, Kant undertakes a methodological-transcendental turn in his ether-conception, which he conceives as a postulate of reason in favor of experience. Only from this perspective is an ether-deduction possible that can reconstruct Kant's theory of experience through an epigenetic foundation of matter. For this to be possible, the ether must constitute a legitimate and active hypostatization of space that explains the different properties of matter. This concept makes possible a new articulation of the concept of experience as a system of perceptions, in which the empirical knowledge is guaranteed by a material-transcendental support capable of systematizing empirical physics. But even more important, this concept allows us to conceive an epigenesis of matter, through what we have called material self-affection. Kant points out that the material, as a thing in itself = X, is a mere representation of the subject's activity, through which it affects itself. Naturally, we are not dealing here with the formal self-affection of the KrV, but with a certain self-affection that involves the spontaneity of the subject understood as an active force of transcendental matter. This dark movement must be understood as follows: 1. The transcendental subject projects his activity as real opposition of moving forces that fill the space on the basis of ether (hypostatization of space). 2. From a transcendental point of view, the moving forces affect the subject in general in his encounter with matter. 3. Given that the ground of empirical affection presupposes a transcendental matter, and given that such matter finds the origin of its activity in the subject itself, the subject's self-affection through the thing in itself = X, is nothing more than a material self-affection. Along with offering clarity about the transcendental epigenesis of matter, this theory shows that the concept of the thing in itself has evolved from the KrV to the Opus postumum, assuming all the functions of both the transcendental matter and the substratum, of the transcendental force, of the transcendental ideal, etc. From here, Kant elaborates his outlines of a theory of metaphysical schematism (Styx interfusa), in which the scientific experimentation of matter acquires a categorical configuration in its asymptotic approach towards the omnitudo realitatis. Only this material-transcendental grounding of experience can finally justify the synthetic judgments a priori in physics, and concretize the original project of a metaphysica cum geometria iuncta. All this development, however, was already announced both in the prologues and at the end of the KrV (A 846) under the name of immanent physiology.
