Time is one of the organisers of the mind. How does one develop the sense of time, from the first proto-mental formations to the consciousness of time? The phenomenological-existential perspective of time, the cyclical dimension and the temporality of physiological processes are connected to the rhythmic nature of early inter-corporeality, leading to experiences that are only possible over time and are organised into increasingly complex units. Various dimensions of the relationship with time are explored—chronological time, subjective time, temporality, temporalisation, historicisation, and progression. The precursors of the sense of time are organised from the archaic levels of psychic functioning, the body—the stage of physiological phenomena—to the pre-verbal modalities of communication and symbolic order that result in the consciousness of time, from which we highlight Freud's early contributions and André Green's work. Psychopathology is a privileged source of indirect observations that can help reconstruct the developmental path of the sense of time. From psychopathological phenomenology to the similarities between Heidegger's philosophical language and André Green's psychoanalytic discourses, we conclude this essay with clinical vignettes resulting from clinical work with adult patients, applying the concepts of associative reverberation, heralding anticipation, associative irradiation, and movement.
