all nature is akin, and the soul has learned all things; there is no difficulty in her eliciting or as men say learning, out of a single recollection all the rest, if a man is strenuous and does not faint; for all enquiry and all learning is but recollection.
Plato states the anamnesis doctrine at its most explicit: all learning is ontologically prior recollection, rendering genuine teaching impossible and inquiry a recovery of what the soul already contains.
, Meno, -385thesis
