Lekton, Meaning, Nonsense

In Logic of Sense, Deleuze argues that the ancient Stoic 'Lekton'--rendered in the English translation of this work as 'Sense', not to be confused with the Fregean term--is the substratum of all varieties of  'meaning' presented by rival theories, including Frege's.  Furthermore, by showing how Lekta function in the writings of Lewis Carroll, he concludes that Meaning originates in Nonsense, thereby subverting the rationalistic ambitions of those rivals.  However, he does not examine the process by which a Neologism only gradually acquires Meaning through repeated usage, e. g. 'copacetic', or, more tellingly, his own idiosyncratic stipulations.  So, he does not consider that the 'nonsensicality' that he attributes as a positive property of a Lekton, derives from the inherent meaningless of a mere sequence of sounds or script.  So, perhaps a headless grin is an apt Carrollian image of the concept of 'Meaning in-itself'.
