From the perspective of Winnicott’s theoretical framework, this paper explores the phenomenon of silence commonly observed in clinical psychotherapy, including the patient’s need for silence and the therapist’s use of silence as a technique. For certain patients, silence is an indispensable part of the therapeutic process and requires the therapist’s understanding and permission. Simply viewing the patient’s silence as a form of resistance may result in missing the opportunity to deeply understand the subtle nuances and significant meanings inherent in the silence itself. The therapist’s use of silence as a technique can be seen as a complement to interpretative techniques. For patients with psychotic components in their personality, silence may emerge during the mid-phase of therapy. This silence often indicates that the patient is entering a contemplative phase, during which they need silence to further integrate their personality. In this process, the therapist must keep silent and allow the patient to be silent to meet their psychological developmental needs. Furthermore, the effective application of silence is closely related to the therapist’s maturity, emotional stability, and inner ego-strength. When the therapist keeps silence at an appropriate moment, it can provide strong support and empathy for the patient, facilitating personality integration. However, if the therapist keeps silent at an inappropriate time or fails to keep silence when necessary, it may have a negative impact on the patient and even hinder the therapeutic process.
