The aim of this research is to explore what relations self-affection bears to the intuitions of inner sense. I propose that self-affection makes some contribution to formal intuitions and empirical consciousness by arguing that the functions of self-affection consist respectively in conceptualising and conscious-making. I begin by examining Kant’s concept of inner sense and point out that inner sense as a receptive faculty depends on self-affection. In so doing, I emphasise that self-affection includes both a pure and an empirical aspect (...) which corresponds to Kant’s distinction between the transcendental synthesis of imagination and the empirical synthesis of apprehension. Then, I focus on the pure aspect and argue that the conceptualising function involved in the pure self-affection is decisive for the generation of formal intuition. In particular, I explain why the formal intuition of time depends on the intuition of space and how it is constituted by drawing a line. After that, I turn to analysing the empirical aspect of self-affection and show that by virtue of the empirical synthesis of apprehension one is aware of both the empirical contents of representations and the mental actions performed on them, whereby I suggest that this empirical conscious-making function can be understood as an act of distinguishing from a mereological point of view.
