This entry examines the intersection of existential philosophy and psychotherapy, with a particular focus on its application to individuals living with disabilities. Grounded in the work of key thinkers such as Kierkegaard, Nietzsche, and Sartre, it explores how existential concepts—freedom, authenticity, and meaning-making—have shaped therapeutic modalities and how they can be used to address existential issues of disability. Rather than treating disability as a deficit, existential therapy emphasizes the individual’s capacity for self-definition, agency, and psychological growth. By addressing the deeper questions of identity, suffering, and purpose, these approaches offer a holistic and empowering framework for psychological support.
