The final paradox: a systems-theoretical account of suicide

Purpose This paper develops a systems-theoretical account of suicide as a terminal form of psychic self-reference. We aim to move beyond risk factor and dysfunction models by reconstructing suicide as a structurally coherent event within autopoietic psychic systems. We ask how, and under what conditions, a psychic system ceases its own operability when its self-referential dynamics become saturated across operational, reflective and reflexive levels. Design/methodology/approach The article offers a systems-theoretical reconstruction of suicide applying Luhmann’s theory of autopoietic systems to psychic systems, differentiating three forms of self-reference and analyzing their interrelations. Findings The analysis suggests that suicide can be described as a structurally saturated configuration of self-reference in which the psychic system continues to operate while at the same time configuring the conditions for its own cessation. Basal, reflective and reflexive self-reference converge into a closed loop that no longer generates meaningful variation. Suicide thus appears as a paradoxical terminal event: the point at which the system’s autopoiesis succeeds so consistently in reproducing its own form that this very success results in the completion and shutdown of further operations. Originality/value The paper provides what is, to our knowledge, the first coherent systems-theoretical theory of suicide grounded in the concept of autopoietic psychic systems. By reconstructing suicide as structurally saturated self-reference, it offers a novel conceptual vocabulary for suicidology. At the same time, it demonstrates how a shift in psychological theory – from substance-based notions of the psyche to systems-theoretical accounts – can be translated into a formally rigorous description of a paradigmatic phenomenon at the limits of psychic self-reference.
