Self-illness ambiguity is a difficulty to distinguish the ‘self’ or ‘who one is’ from one's mental disorder or diagnosis. Although self-illness ambiguity in a psychiatric context is often deemed to be a negative phenomenon, it may occasionally have a positive role too. This paper investigates whether and in what sense self-illness ambiguity could have a positive role in the process of recovery and self-development in some psychiatric contexts by focusing on a specific case of mental disorder – anorexia nervosa.

In their target article, Moore and colleagues offer a valuable overview of the various ambivalence-related phenomena that may impede swift clinical decision-making. They argue that patients...

ABSTRACT‘If I experience X, is it because of the illness, the medication, or is it ‘just me’?’ (Karp 2009) [Is it me or my Meds? Living with Antidepressants. Harvard University Press]. This issue is known as self-illness ambiguity (SIA) (Sadler 2007) ["The Psychiatric Significance of the Personal Self." Psychiatry: Interpersonal and Biological Processes 70 (2): 113–129]. In her paper Know Thyself: Bipolar Disorder and Self-concept, Carls-Diamante (2022) [“Know Thyself: Bipolar Disorder and Self-Concept.” Philosophical Explorations, 1–17] offers a taxonomy of different (...) ways in which Bipolar Disorder can be related to one’s self and self-concept. In contrast to the essentialist model of mental disorders she seems to adopt, I propose a different outlook on SIA, following an enactive approach to psychiatric disorders as disorders of sense-making. One’s way of making sense of the world and/or oneself can become stuck in a rigid pattern that is stronger than oneself and at odds with how one would want to be. I argue that it is helpful to distinguish between the experiential SIA of specific experiences (Am I over/underreacting?) and the long term concerns of existential SIA (How to live my life in accordance with what matters to me despite/while having certain vulnerabilities?). I conclude that knowing oneself is not an intra-individual matter, nor primarily a matter of reflection: it is rather a relational and material practice of trying to live your life in accordance with what matters to you.

ABSTRACT This paper investigates from a phenomenological perspective the origins of self-illness ambiguity. Drawing on phenomenological theories of affectivity and selfhood, I argue that, as a phenomenon which concerns primarily the ‘personal self’, self-illness ambiguity is dependent on distinct alterations of affective background orientations. I start by illustrating how personhood is anchored in the experience of a specific set of non-intentional affects – i.e. moods or existential feelings – alterations of which are often present in mental ill-health. Also through the (...) exploration of the phenomenology of acute and long-term anxiety, I suggest that self-illness ambiguity originates in the presence of moods or existential feelings that are in tension with the ones that structure the person’s experience prior to the onset of the illness or when its symptoms are not experienced. More specifically, I claim that due to their ability to ‘block’ or ‘suspend’ some of the person’s affective and cognitive responses, such affective orientations may unsettle one’s self-defining evaluative perspective, leading to uncertainty and doubting about one’s personal self.
