What is spiritus Mundi?

Spiritus Mundi is a Latin term meaning "world spirit" or "spirit of the world." It is often associated with the idea of a collective unconscious or a shared pool of human experiences, memories, and archetypes, suggesting that creativity and inspiration can draw from this universal repository. The term is famously used by poet W.B. Yeats in his work, reflecting his belief in a deeper connection among humanity and the influence of this collective spirit on individual creativity.
