The advantage of the 'writing' subject over the 'speaking' subject.

According to Lacan, once conscripted into the Symbolic Order of language we no longer function as gratifying wholes but as subjects divided, the unconscious mind being bound to have its say in collaboration with the conscious whenever we write or speak. 

But if the Speaking Subject can but go blindly ahead, signifying freely, the Writing Subject is in a different case, because he or she – or better, it – can go back over what has been written, to give greater order to it.
