contexts always accompany the printed word. But if print 
discourages minute verbal play, it strongly works for uniformity 
of spelling and uniformity of meaning, since both of these are 
immediate practical concerns of the printer and his public.

     In the same way, a written philosophy, and especially a 
printed one, will naturally make “certitude” the primary object 
of knowledge, just as the scholar in a print culture can have 
acceptance for his accuracy even though he has nothing to 
say. But the paradox of the passion for certitude in print 
culture is that it must proceed by the method of doubt. We 
shall find abundance of such paradoxes in the new technology 
that made each book reader the centre of the universe and also 
enabled Copernicus to toss man to the periphery of the 
heavens, dislodging him from the centre of the physical world.
