This book extends the contemporary concept of the minimal self by introducing the affective core self. The overall aim is to integrate certain psychoanalytical ideas into the phenomenological investigation of passivity and reformulate the idea of the phenomenological unconscious. This volume contributes to the multidimensional analysis of the self by positioning the affective core self between the layers of the more minimal and the less minimal self. It underscores the importance of the unconscious in the constitution of the affective core self by providing the comparative analysis of the phenomenological and the psychoanalytical unconscious. Furthermore, comparisons are drawn between Freud’s conception of the afterwardsness of trauma and the phenomenological notion of retroactive sense-constitution. The book concludes that retroactive sense-making is a double-sided phenomenon and differentiates between implicit-bodily and conscious-narrative retroactive sense-constitution. In order to bolster the idea of implicit-bodily sense-constitution the volume also examines and utilizes contemporary insights on the nature of body memory. The conclusion claims that the affective core self is constituted in time by means of the underlying processes of the two-sided retroactive sense-constitution. This text appeals to students and researchers working in phenomenology and philosophy of mind.
