III. Examination of the evidence yielded by the _Reflexionen_ and _Lose Blätter_ in support of the above analysis. IV. Connected statement and discussion of the total argument of the deduction. =I. Enumeration of the Four Stages= (1) FIRST STAGE: THAT OF THE TRANSCENDENTAL OBJECT, WITHOUT CO-OPERATION OF THE CATEGORIES.--This stage is represented by[754]: (_a_) II. 3 (from beginning of the third paragraph to end of 3) = A 104-10; (_b_) I. § 13 (the entire section) = A 84-92 (retained in second edition as B 116-24). _a_ discusses the problem of the reference of sensations to an object, _b_ that of the objective validity of the categories. _b_ is therefore transitional to the second stage. (2) SECOND STAGE: THAT OF THE CATEGORIES, WITHOUT CO-OPERATION OF THE PRODUCTIVE IMAGINATION.--This stage is represented by: (_a_) I. [§ 14] (with the exception of its concluding paragraph) = A 92-4 (retained in second edition as B 124-7); (_b_) II. (the first four paragraphs) = A 95-7; (_c_) II. 4 (the entire section) = A 110-14. (3) THIRD STAGE: THAT OF THE PRODUCTIVE IMAGINATION, WITHOUT MENTION OF THE THREEFOLD TRANSCENDENTAL SYNTHESIS.--This stage is represented by (_a_) III. β (from beginning of seventh paragraph to end of twelfth) = A 119-23; (_b_) III. α (from beginning of third paragraph to end of sixth) = A 116-19; (_c_) I. § 14 (Concluding paragraph) = A 94-5; (_d_) III. δ (from beginning of sixteenth paragraph to end of section preceding summary) = A 126-8; (_e_) S(ummary) (in conclusion to III.) = A 128-30; (_f_) III. γ (from beginning of thirteenth paragraph to end of fifteenth) = A 123-6; (_g_) I(ntroduction) (from beginning of section to end of second paragraph) = A 115-16; (_h_) § 10 T(ransitional to the fourth stage) = A 76-9 (retained as B 102-4). (4) FOURTH STAGE: THAT OF THE THREEFOLD TRANSCENDENTAL SYNTHESIS.--This stage is represented by: (_a_) II. 1-3 (from opening of 1 to end of second paragraph in 3) = A 98-104; (_b_) II. (the two paragraphs immediately preceding _a_) = A 97-8. =II. Detailed Analysis of the Four Stages= =First Stage.=--A 104-10; A 84-92 (B 116-24).
