In the individual’s soul’s life, the Other is invariably involved, as a model, as an object, as a helper and as an oppponent.

My own translation, wich is already a lacanian interpretation.

In the individual’s mental life someone else is invariably involved, as a model, as an object, as a helper, as an opponent.

Translated from german byJames Strachey

Dans la vie d’âme de l’individu, l’autre entre en ligne de compte très régulièrement comme modèle, comme objet, comme aide et comme adversaire.
