The notion of the subject as conceived by Jacques Lacan should not be conflated
with the subject as conceived by linguists or philosophers or other academic theorists
concerned with this notion. For Lacan, the subject is empty, meaning that it neither pertains
to relationality nor to positivity. Neither a positive determination can be predicated
upon the subject, as is the case in traditional logic and linguistics, nor is the subject to be
regarded as some sort of thinking substance, as is the case for modern philosophy, that is,
philosophy since Descartes.
