It becomes language, but only at the end of definite and complex operations: the notation of an analogy of relations (the other's cry is to what he is experiencing that which is unknown what my cry is to my appetite or my fear); inversion of time and voluntary use of the sign before the representation it designates (before experiencing a sensation of hunger strong enough to make me cry out, I emit the cry that is associated with it); lastly, the purpose of arousing in the other the representation corresponding to the cry or gesture (but with this particularity, that, by emitting a cry, I do not arouse, and do not intend to arouse, the sensation of hunger, but the representation of the relation between this sign and my own desire to eat).
