 Throughout "Finnegans Wake" Joyce specifies the Tower of Babel as the tower of Sleep,
that is, the tower of the witless assumption, or what Bacon calls the reign of the Idols.His episodic and often rambling history takes the reader from pre-alphabetic tribal humankind to the electronic age.According to McLuhan, the invention of movable type greatly accelerated, intensified, and ultimately enabled cultural and cognitive changes that had already been taking place since the invention and implementation of the alphabet, by which McLuhan means phonemic orthography.
