Twenty third in a series

John Lennon sang, "the Walrus was Paul," but that may only have been because when he wrote, "I am the Walrus," he was thinking of Lewis Carroll's poem, "The Walrus and the Carpenter." Except he hadn't read the poem in a while, and forgot that the Walrus is a pretty bad fellow.

I remember reading somewhere that the poem is an allegory about Kantian and Utilitarian ethics - perhaps here - but it seems unlikely that was what John was thinking about.
