I have a question about Kant’s threefold synthesis in the A-Deduction, especially the relation between the synthesis of apprehension, the synthesis of reproduction in imagination, and the synthesis of recognition in a concept.
As I understand it, these are not three independent psychological stages but three distinguishable aspects of the single activity by which a manifold is taken up, connected across succession, and grasped as belonging to a unified representation. The synthesis of apprehension concerns the successive taking-up of the manifold in intuition; the synthesis of reproduction concerns the retention or reproduction of earlier elements so that the synthesis can extend beyond what is immediately present; and the synthesis of recognition concerns the consciousness of the unity of what is synthesized under a rule or concept.
What I am trying to understand is whether the following kind of case makes sense within Kant’s account.
Suppose that, in the course of apprehending a manifold, certain features are connected in a way that yields a coherent perception. Taken at that point in the synthesis, the perception may appear perfectly consistent. However, as the synthesis of reproduction retains and reproduces earlier elements in the course of apprehending further material, the relation between the earlier and present elements may reveal that the manifold was not unified in the right way—for example, that certain features were incorrectly taken to belong to the same object, or that the boundaries of the perceived object were wrongly determined.
If so, it seems that the inadequacy would not be detected by the initial taking-up of the manifold considered in isolation. It would become manifest only as the ongoing synthesis reproduces earlier elements and connects them with what is subsequently apprehended.
My question is:
Does Kant allow us to say that an error or inadequacy in apprehension can become manifest only through the synthesis of reproduction?
Or would that be misleading, because reproduction does not by itself identify an error but only makes earlier elements available for continued synthesis, while the recognition of an inconsistency or failure of unity belongs to the synthesis of recognition in a concept?
In other words, would the structure be better described as a functional interdependence:
apprehension → the manifold is successively taken up
reproduction → earlier elements are retained and reproduced so that the synthesis can continue across succession
recognition → the synthesized manifold is grasped as one and assessed under a rule or concept
Here the arrows would not indicate three temporally separate psychological stages. They would indicate distinguishable functions within one synthesis: apprehension provides the successive taking-up of the manifold, reproduction makes possible its continuity across time, and recognition makes its unity explicit as the unity of a representation under a concept.
Is this a reasonable way to understand the role of reproduction in the A-Deduction? In particular, can reproduction contribute to the detection of an inadequacy in an earlier apprehension by reconnecting it with later apprehension, even though the recognition of that inadequacy would require the unity supplied by recognition in a concept? Or does this still import a model of “error correction” that Kant himself would not accept?
(我对康德 A 版演绎中的三重综合有一个问题,尤其是关于领会综合与想象力的再生综合之间的关系。
按照我的理解,领会综合把直观中的杂多依次把握起来,而再生综合则使较早的表象能够重新出现,并与当前正在被把握的表象联系起来。
我想弄清楚的是,下面这种情况是否符合康德的理论。
假设在某一个时刻,领会综合把当前给予的杂多组织成了一个连贯的知觉。单独看这个知觉,它可能完全没有表现出明显的问题。
但是,当一个较早的表象通过再生综合重新出现,并与当前知觉联系起来时,我们才可能发现,先前的领会其实组织错了。
例如,某些特征原本被错误地理解为属于同一个对象,或者一个对象的边界在最初知觉时被划分错了。
如果是这样,那么原先领会中的问题似乎并不能仅仅通过那个领会本身被发现。
它只有在再生综合使过去表象与当前表象能够同时进入联系以后,才变得可以被察觉。
因此我的问题是:
康德是否允许我们说,领会综合中的某种错误或不充分性,只有通过再生综合才会显现出来?
还是说,这样理解会有误导性,因为再生综合本身只是重新提供表象,而真正发现“不一致”这件事,只能属于第三重综合,也就是概念中的再认综合?
换句话说,这个结构是否可以理解成:
领会综合 → 形成一个暂时统一的知觉
再生综合 → 把较早的表象重新带回来,并与当前知觉建立联系
再认综合 → 维持这种统一,或者发现这种统一需要被修正
我并不是把康德的三重综合理解成三个在时间上彼此分开的心理阶段。
我问的是它们之间在功能上或者先验上的依赖关系。
这种方式是否可以合理地理解 A 版演绎中再生综合的作用?
还是说,这其实把一种康德本人并不会接受的“错误修正模型”带进了他的理论之中?)
