for freud, as is well known, the human psyche is a stratification of tokens or representatives. one term is constituted by the manifest meaning of behaviour, another, by its latent or real meaning (it is, for instance, the substratum of the dream); as for the third term, it is here also a correlation of the first two: it is the dream itself in its totality, the parapraxis (a mistake in speech or behaviour) or the neurosis, conceived as compromises, as economies effected thanks to the joining of a form (the first term) and an intentional function (the second term)
