    中文摘要 康德式的“哥白尼革命”要求对象依照先验知识,这类知识可以在经验显象(Erscheinung,appearance)被给予之前就对对象有所断定;而且关于对象的知识必须是先天综合的。为了完成这样的任务,我们就需要设定一种对象,它既能够先天地代替经验显象,又能够在先验知识的各种能力的联结中发挥作用,以使关于显象的先天综合判断得以可能。正是在这样的理论背景下,先验对象的重要作用被凸显出来。 但学界似乎并未对先验对象概念之含义予以足够重视。在通常的理解中,先验对象(das transzendentale Gegenstand)与先验客体(das transzendentale Objekt)被等同起来,进而与自在之物(Ding an sich selbst)的含义相同。 针对这样的解读,本文坚持应尊重《纯批》原意,并充分地将此概念与意义相近的诸概念之异同予以厘定。在H.J.Paton,Graham Bird,Henry Allison等康德专家的相关思想指引下,本文围绕着澄清先验对象概念之含义的中心任务,分别从A版纯粹知性概念的主观演绎、先验观念论、经验实在论以及B版纯粹知性概念的演绎四个方面开展概念辨析工作。 康德在A版纯粹知性概念的主观演绎中对先验对象概念予以详细介绍。其中,该概念被理解为一个先天的表象的对象,它提示着对可能的经验杂多所施加的一种先天的综合统一作用。先验对象与先验统觉的联结使对可能的经验杂多的综合统一作用得以可能,并同时为经验性杂多带来客观性。另一方面,先验对象作为一个先天的对象概念,它不包含任何经验感性杂多,它是非经验的,但不能据此就将先验对象误解为自在之物。 先验对象概念的重心在于“先验”。康德意义上“先验”概念强调了“认识先天可能对象”的知识。再联系康德的先验知识和先验反思,本文主张在认识论、而非本体论立场上理解“先验”概念。在此意义上,先验对象并不是指称了一种本体论中实存的对象;相反,该概念是一种理论上的设定,它帮助我们认识与先验知识相关的诸能力,让我们厘定了先验知识的范围、界限、客观有效性等重要认识论问题。 先验观念论的背景中的先验对象概念,与自在之物和先验客体等概念有了更多的纠葛。在此部分中,本文首先驳斥了传统中“自在之物是感性刺激的来源”这个命题;再根据认识论中“两个方面解释”(the two-aspect view)将自在之物的核心意义理解为消极意义上本体概念。要言之,先验观念论中自在之物与显象并不是两个不同的、实存(Existenz/existieren)着的对象。它们只是我们对同一个经验显象(Erscheinung)的两种不同设想。自在之物概念警示我们:先验知识不能脱离经验显象的限制,而进入到有关自在对象的讨论中。在澄清了自在之物的含义后,它与先验对象的差别就明晰地厘定出来。 另外,先验客体概念包括两层含义。一方面,先验客体与先验对象相近,表示了一种与先验统觉相关联、能够对可能的感性直观杂多起到综合作用的概念。另一方面,尤其是根据先验辩证论中的相关表述,先验客体又可以被解读为积极意义上的自在之物概念,即作为经验显象的先验基础或原因。面对这样悖论性的解释,本文主张以康德意义上的理性的构成性原则与调节性原则为解释依据。在理性的理论运用中,康德依据理性的构成性原则,强调可以在先验层次上理解经验显象,相应地有了先验对象与经验显象的认识论联系;在这个意义上,先验对象与先验客体概念含义相近。但在理性的实践运用中,康德依据理性的调节性原则,把先验客体解释为理性体系中显象的先验基础;在此意义上,先验客体与先验对象区别开来。 经验实在论者需要直接承认经验显象中质料的实存。对此就需要区分“实在性”和“现实性”两个不同概念。经验实在论真正关心的是经验中现实地实存着的质料(Materie),显象质料可以经验性地刺激感官,使内心获得有关质料实存的实在性表象。与显象质料密切相关的另一个概念就是实体(Substanz)。康德承认经验中持存着的个体显象是相对性实体;但更为本质的是,个体显象中所包含的不变的质料的量才是绝对意义上持存的实体。因为实体概念涉及显象中质料的存有(Dasein),所以我们无法先天地利用实体--偶性范畴去直接规定经验中显象质料的存有;我们只能诉诸于经验类比的方式间接地推论出质料显象的持存性实体。 通过对实在经验相关的质料和实体等概念的讨论,本文可以更清楚地阐释先验对象概念的含义。先验对象提示了一种对可能的感性杂多的综合统一作用。但质料的存有和不同存有的关系(比如实体-偶性关系)是不能完全地被先天规定的,而只能在经验中确定具体的存有以及存有关系。在此意义上,尽管质料的存有以及存有关系都属于显象畛域,但质料存有和实体等经验性持存物不能被先天地综合在可能的经验对象之中。先验对象中所综合统一的可能的感性杂多仅只是限于一般感觉。 本文最后讨论的是B版纯粹知性概念演绎与先验对象的关系。B版演绎起始于先验统觉概念。该概念的形式性、自我同一性、客观实在性中“客观”性是准确把握先验统觉概念的关键。由先验统觉向想象力的演绎过渡中,生产性想象力的概念被提出,该想象力在先验层次上对可能表象的杂多起到综合作用。在B版演绎中,被生产性想象力所综合的、先天地代表着经验显象杂多的对象是一般感官对象(Gegenstaende der Sinne ueberhaupt)。又通过分析一般感官对象在B版演绎中的位置、它与先验统觉的关联、由其为先验知识所带来的客观实在性;这些特征与A版主观演绎中的先验对象概念基本相同。这些分析证明了:虽然康德并没有在B版演绎里直接使用先验对象概念,但因为一般感官对象在含义更加清楚,且与先验对象含义相同;所以先验对象概念在B版演绎中仍保留重要位置。 总之,通过分析A版主观演绎中先验对象概念的含义,先验观念论中先验对象概念与自在之物、先验客体等概念的异同,经验实在论中由质料存有、实体概念所带来的一般感觉对先验对象的联系,以及B版演绎中与先验对象拥有相同含义的一般感官对象,我们对先验对象概念之含义做了最终的澄清:先验对象并不是自在之物;也在《纯批》的多数语境中,与作为积极意义上自在之物的先验客体区分开来。在本文所做的认识论解读中,先验对象概念能够先天地代表感性杂多,能够被生产性想象力综合为一个对象的形象,与统觉的联结又使该概念提示出对可能经验杂多的综合统一作用。在此意义上,澄清先验对象概念之含义对充分把握康德的批判哲学起到了重要作用。 关键词:先验对象,先验客体,自在之物,先验观念论,先验统觉。 中图分类号:B516.31
    英文摘要 Kant's "Copernican Revolution" requires that objects must conform to the transcendental knowledge, i.e., the knowledge can make determinations of the empirical appearances before they are given; and that the knowledge about the objects must be a priori synthetic. In order to accomplish these tasks, we have to postulate an object which both can a priori stand for empirical appearances, and can play a critical role in the connection of various elements of the transcendental knowledge so that the a priori synthetic judgments about the empirical appearances are made possible. Against such a theoretical background stands the importance of the Concept of Transcendental Object out. However, Kantian scholars do not attach due importance to the concept. In ordinary understanding, the Transcendental Object (Gegenstand) concept (hereafter referred to as TOG) is identified with the Transcendental Ob-ject (Objekt) ((hereafter referred to as TOO), and both of them are further identified with the Thing- in -itself. In contrast to such a reading, this paper intentionally adheres to the meaning of CPR and discriminates the concept as such from other concepts in terms of denotation. Under the intellectual guidance of such Kantian experts as H. J. Paton, Graham Bird, and Henry Allison, this paper, targeted at the clarification of the TOG, unfolds its conceptual discrimination from four aspects; namely, they are the 1〓 edition of TD, the Transcendental Idealism, the Empirical Realism, and the 2〓 edition of TD. Kant elaborates on the TOG in detail in the 1〓 edition of the Deduction of the Pure Concepts of Understanding (hereafter referred to as TD) in Critique of Pure Reason (hereafter referred to as CPR). The TOG in the 1〓 edition can be understood as an object of representations a priori, and it signifies the possible empirical manifold combined a priori in a synthetic unification. The connection between TOG and the transcendental apperception makes the synthetic unification possible and brings the objectivity to the empirical manifold. Meanwhile, the TOG, an a priori concept of object, does not contain any empirical manifold of sensibility; it is non-empirical, but, even on this basis, the TOG can't be misunderstood as Thing-in-itself. The emphasis of TOG concept is laid on "transcendental". In Kantian sense, the "transcendental" concept emphasizes the knowledge of the "cognition of possible object a priori". In association with the Kantian transcendental knowledge and transcendental reflection, the paper argues that the "transcendental" concept should be understood on the epistemological, rather than ontological, perspective. In this sense, the TOG does not refer to an entity which ontologically exists. On the contrary, it is a theoretical postulation which helps to recognize various cognitive abilities related to the transcendental knowledge and to delimit the scope, boundaries, and objective validity of transcendental knowledge in the field of epistemology. In the Transcendental Idealism, the TOG concept tangles in greater degree with the Thing- in- Itself and the TOO. In this regard, this paper refutes, in the first place, the proposition traditionally accepted as "the Thing-in- Itself originates the affection of sensibility." Then, based on the Two- Aspect View of epistemology, this paper defines the core meaning of the Thing- in- Itself as Noumenon in the negative sense. Concisely, the Thing- in- Itself and the Appearance are not so two distinctive entities as two different aspects of one and the same one empirical appearance. The Thing- in-Itself concept alerts us that the transcendental knowledge can't step over the boundary of empirical appearance for the sake of itself. After the above clarification, the Thing-in- Itself concept clearly discriminates from the TOG. In addition, the TOO concept has two-fold meanings. On one hand, TOO is close in meaning to TOG, both of which signify, in association with the transcendental apperception, the combination of the possible manifold of sensuous intuition. On the other hand, in particular on the basis of the Transcendental Dialectic, TOO can be interpreted as the Thing- in- Itself concept in the positive sense; i.e., it serves as the cause of or lays the foundation for empirical appearances. Faced with these paradoxical interpretations, this paper upholds the Kantian constitutive and regulative principles of Reason in the interpretation. In the theoretical application of Reason, Kant, on the basis of the constitutive principle, stresses the transcendental understanding of the empirical appearance; and accordingly, establishes the epistemological connection between the TOG and the empirical appearance. In this sense, TOG and TOO are close in meaning. However, in the practical application of reason, Kant, on the basis of the regulative principle, interprets the TOO as the transcendental cause of appearance in the system of reason; in this sense, TOO discriminates from TOG. An empirical realist has to directly admit the existence of matter of empirical appearance. For this sake, the "reality" should be distinguished from the "actuality". What the empirical realist really cares about is the matter which actually exists in experience. The matter of appearance can empirically affect the senses and then the mind can receive the real representation about the existence of the said matter. Substance is another key concept which is closely related to the matter of appearance. Kant recognizes the permanent individual entity of empirical appearance as the relative substance; but more essentially, the permanent quantum of matter which is contained in the individual appearance is the absolute permanent substance. Moreover, because the substance concept concerns the existence of matter of appearance, the Inherence-- Subsistence category can't be used a priori to directly determine the existence of matter of the empirical appearance. We can only turn to the empirical analogy to indirectly deduce the permanent substance of the appearance matter. After the discussion about the matter and substance in relation to the real experience, this paper can elucidate the meaning of TOG more clearly. The TOG signifies the possible manifold of sensibility combined in the synthetic unification; but the existence of matter and the relationship between different entities (such as substance and its attributes) cannot be totally determined a priori. Rather they can only be determined in experience. In this sense, although the existence of matter and the relationship between different entities both belong to the realm of appearance, such empirically permanent entities as the existence of matter or substance cannot be combined a priori in the possible object of experience. The possible manifold of experience combined in the TOG can be no more than the sensation in general. The last section of the paper body is about the relationship between the 2〓 edition of TD and the TOG. The deduction of the 2〓 edition initiates from the transcendental apperception concept which can only be correctly interpreted on the basis of its formality, self-identity, and the "objectivity" in the relevant objective reality. In the transition from apperception to imagination, the productive imagination is brought forward, which combines, on the transcendental level, the possible manifold of representation. In the 2〓 deduction, it is the object of the senses in general that is combined by the productive imagination and that can represent a priori the manifold of empirical appearance. The analysis is further extended to the locality of the object of senses in general in the 2〓 edition, to its relation with the transcendental apperception, and to the objective reality it brings to the transcendental knowledge. All these properties are almost the same as those of the TOG in the 1〓 edition. This comparison proves that the TOG still retains its crucial locality in the 2〓 edition deduction, though its literal expression can't be directly found in the 2〓 edition; and the object of senses in general is clearer in meaning and is the same as TOG. All in all, after the analyses are made in the meaning of TOG in the 1〓 edition of TD, in the comparison with the Thing- in- Itself and TOO in Transcendental Idealism, in the relationship between TOG and the sensation in general brought forward by the real matter and substance in the Empirical Realism, and in the identity with the object of senses in general in the 2〓 edition of TD, we finally elucidates the meaning of TOG: TOG is not thing-in-itself and, in most contexts of CPR, differs from the TOO equivalent to thing-in-itself in the positive sense. In the epistemological reading of the paper, TOG can a priori stand for the manifold of sensibility, can be synthesized into a figure of an object by the productive transcendental imagination, and can, in connection with the apperception, signify the synthetic unification of the possible empirical manifold. In this sense, the clarification of the meaning of TOG is indispensable for the tenacious grasp of the Kantian Critical Philosophy.
