Contemporary positive psychology has reclaimed “spirituality” as a measurable variable correlated with well-being, resilience, and lower rates of depression. Researchers define it operationally as “the search for the sacred” or “a sense of connection to something larger than oneself.” In this frame, spirit does not require a deity—it requires transcendence of the ego .

Carl Jung distinguished spirit from intellect: spirit is the archetypal principle of meaning, numinosity, and wholeness. In his view, modern neurosis stems from “loss of spirit”—reducing humans to drives (Freud) or statistics (behaviorism).

The German Idealist G.W.F. Hegel revolutionized the concept with Geist —usually translated as “Spirit” or “Mind.” For Hegel, Spirit is not an otherworldly ghost but the very structure of reality coming to self-consciousness through history, art, religion, and philosophy. Spirit is the movement of the individual recognizing themselves in the other, and humanity recognizing itself as free.

In classical theism (Christianity, Islam, Judaism), Spirit (often capitalized as Holy Spirit or divine spirit) is a hypostasis of God—the active, creative force in the world (Genesis 1:2: “The Spirit of God was hovering over the waters”). Simultaneously, spirit denotes the immortal human soul, that which survives bodily death.
