The term vitality, as well as the phenomenon meant by this, has rather fallen out of fashion. It encompasses everything which has something to do with the dynamic form of human experience. For example, feelings do not ‘exist’, they ‘show’ themselves in a specific way. One learns from the first breath of life how people structure their internal life, express their feelings and react to others. Is it relaxed or tense, strong or weak, clear or vague, fluent or hesitant, explosive or gentle, pointed or blunt, loose or constrained, firm or fluid (melting) and many more.
Vitality phenomena, metatheoretically, have an incredibly important role in understanding and changing psychological systems. The ability to perform, the capacity for happiness, the social resonance, the relationship stability, the creativity, the physical health, the richness of expression, the resilience and robustness, all these are connected, directly or indirectly, with the vitality of a person. Likewise, phenomena such as depression, burn-out, inauthenticity, substitute needs strategies, the seeking of conflict, manic urges and much more, cannot be understood without the history, which a human has experienced with regard to his vitality.
