anamnesis

Anamnesis comes from Ancient Greek anamnesis, a noun recorded by the fourth century BCE. It is built from ana-, meaning back or again, and mnesis, meaning memory or recollection. The family is tied to mimneskein, "to remember," and to Mnemosyne, the goddess Memory. In Athens, Plato gave the word one of its most durable settings.

In Plato's Meno and Phaedo, anamnesis is not ordinary recall but the soul's recovery of knowledge it once possessed. That argument belongs to the late fifth and early fourth centuries BCE, when Socrates and Plato made memory a philosophical problem. The word could still mean simple recollection in wider Greek use. Philosophy gave it a sharper edge by making remembrance into recognition of what was already known.

Greek medical writing also used anamnesis in a practical sense for bringing past facts back to mind. Through late antique and Byzantine scholarship, the term remained available to educated Greek readers. Learned Latin borrowed the Greek form as anamnesis without much reshaping. From there it entered European scholarly vocabulary, especially in theology, philosophy, and medicine.

English adopted anamnesis in learned writing in the seventeenth century. Christian liturgy used it for the memorial recalling of Christ's passion, while physicians used it for a patient's remembered history. Modern psychology and philosophy kept the sense of recovered memory or recollection. The word has stayed technical, but its core motion is still plain: memory brought back.
