"For, it is the opinion of choice virtuosi, that the brain is only a crowd of little animals, but with teeth and claws extremely sharp, and therefore cling together in the contexture we behold, like the picture of Hobbes's Leviathan, or like bees in perpendicular swarm upon a tree, or like a carrion corrupted into vermin, still preserving the shape and figure of the mother animal; that all invention is formed by the morsure of two or more of these animals, upon certain capillary nerves, which proceed from thence, whereof three branches spread into the tongue, and two into the right hand."
— Swift, Jonathan (1667-1745)
Reading Jonathan Swift, A Tale of a Tub and Other Works, eds. Angus Ross and David Woolley. (Oxford: Oxford University Press, 1986). Some text drawn from ebooks@Adelaide.
Note, the textual history is complicated. First published May 10, 1704. The second edition of 1704 and the fifth of 1710 include new material. Ross and Woolley's text is an eclectic one, based on the three authoritative editions.
