《纯粹理性批判》中两版先验演绎之比较

《纯粹理性批判》第一版的先验演绎分为主观演绎和客观演绎，第二版则通过两个相关的证明来进行，即范畴的客观有效性证明和客观实在性证明。比较起来，第一版也包括两个不同的证明，此外，虽然康德在第二版中删除了主观演绎，但并没有删除主观演绎要解决的范畴和直观的结合问题，这说明主观演绎是服务于范畴的客观实在性证明的。因此，两版的先验演绎本质上并没有什么不同。

The Comparison of the A and B editions'Transcendental Deduction in the Critique of Pure Reason

The transcendental deduction in the A edition of the Critique of Pure Reason is constituted by subjective deduction and objective deduction, whereas is constituted by the testifying of the objective validity and objective reality of the categories in the two steps of the proof in B edition. On my opinion, the A edition is also involve the two steps of the proof, moreover, although Kant cut out the subjective deduction in B edition, the issue about the combination of the categories and the institute which the subjective deduction was employed to solve is not cut out, this show that the subjective deduction is subordinate to the testifying of the objective reality of the categories, so, the two versions transcendental deduction are basic the same.
