The term ‘Now’ occupies a peculiarly dense intersection in the depth-psychology corpus, where phenomenological philosophy, contemplative traditions, clinical practice, and neuroscience each assign it a distinct yet overlapping weight. Heidegger’s analysis in Being and Time provides the philosophical ground: ‘now-time’ (Jetzt-Zeit) represents the levelled-off, ordinary conception of temporality, a succession of present-at-hand ‘nows’ that obscures Dasein’s primordial ecstatic temporality. Derrida, reading through Aristotle, presses this further, exposing the aporia of the now’s identity and alterity — the impossibility and necessity of its coexistence with other nows. Against this philosophical tradition, contemplative voices — Watts drawing on Zen, McGilchrist invoking Kierkegaard and Dōgen — rehabilitate the now as an ‘atom of eternity,’ simultaneously dimensionless and everlasting. In depth psychology proper, von Franz situates the now within the psyche’s dual residence in ordinary and aeonic time, while Jung’s autobiographical moment of self-recognition (‘now I am myself’) presents the now as the birth-point of individuation. Clinically, the here-and-now functions as the operative locus of group therapy (Yalom), of somatic tracking (Dana), and of ACT-based defusion (Harris). Lewis’s neuroscientific analysis adds a pathological register: ‘now appeal,’ the excessive present-orientation characteristic of addiction. Taken together, the corpus treats ‘now’ not as a simple temporal marker but as a site of ontological, psychological, and therapeutic contestation.
