First Edition Transcendental Deduction Establish transcendental apperception (the unity of experience specifically for a single consciousness - the “I” in “I think”) The 3-fold Synthesis The Synthesis of Apprehension in the Intuition - the data gathered by the intuition about an object is done over time and are therefore serially apprehended The Synthesis of Reproduction in the Imagination - earlier data in the series must be recalled when later data are experienced The Synthesis of Recognition in the Concept - the connection among the data into a single object is recognized by a concept that links the data as representations or states of the object Paul Guyer (from The Cambridge Companion to Kant’s Critique of Pure Reason) says he would continue the argument thusly: such concepts will be used in judgements; recognizing unity of representations of object under concept is to judge the predicates within the concept are present in the intuition, and therefore formed with structure complementary to the structure of judgement, i.e. the Categories However, Kant continues the argument differently… Relating several representations under a concept as representations of a single object carries a necessity with it since representations of a single object is that which is not arbitrary and therefore a priori insofar as our cognitions are to relate to an object, our cognitions must also agree with each other in relation to the object Our cognitions are related to each other via the transcendental apperception (transcendental meaning that it is a necessary condition) The unity of the transcendental apperception is the connection, known a priori, that brings together the multiple (manifold) serial representations into representations of a single object This connection exists not in the intuition (which contains only the single immediate representation) and so exists in the understanding Therefore the transcendental apperception must employ the rules of the understanding, which are the Categories The 3-fold Synthesis is a priori, being the necessary conditions for experience, and is therefore synthetic a priori Paul Guyer (from The Cambridge Companion to Kant’s Critique of Pure Reason): points out that Kant does not invoke the complementarity of judgement and understanding established in the metaphysical deduction, which would show their isomorphic structures (i.e. the tables shown in the metaphysical deduction); this omission weakens Kant’s argument

Where do the feelings, desire and emotions fit in this theory sir? I know Kant talks about pleasure and pain in Critique of Judgement but do they have any starting point here?
