"While Saussure had gone to great pains to show that language in its most general form could be understood as a system of differences, 'without positive terms', Derrida noted that the full implications of such a conception were not appreciated by either latter-day structuralists, or Saussure himself. Difference without positive terms implies that this dimension in language must always remain unperceived, for strictly speaking, it is unconceptualisable."
