In 1955, Lacan draws a distinction between the ”little other” and the ”big Other” (”the Other”), a distinction which remains central throughout the rest of his work.
The little other is the other who is not, in fact, other, but a reflection or projection of the ego.
The big Other designates radical alterity, an otherness which transcends the illusory otherness of the imaginary because it cannot be assimilated through identification. Lacan equates the big Other with language and the law, and hence the big Other is inscribed in the symbolic order.
In 1957 Lacan illustrates this incomplete Other graphically by striking a bar through the symbol A. Hence another name for the castrated, incomplete Other is the barred Other.
