After recalling Platonic concept of anàmnesis -concept defined also with reference to the different notion of memory, the Greek mnème -, I try to explain the possible gnosiological sense of theory of recollection, laying stress on its relations with the thesis of different levels of knowledge (opinion and science), corresponding to different ontological levels (empiric world and ideal word). Then, I attempt to explain the possible strict connection between the theory of anàmnesis and basilar Platonic ethical concepts such those of purification, happiness and pleasure.
