Leon Craig's <The Platonian Leviathan> 2013 notes “How carefully, how thoroughly and thoughtfully
must Melville have read Hobbes” based on his “profound appreciation of Hobbes's special brilliance []
made most explicite in Israel Potter”
He quotes, “Franklin all over is of a piece. He dressed his person as his
periods; neat, trim, nothing superfluous, nothing deficient. In some
of his works his style is only surpassed by the unimprovable sentences
of Hobbes of Malmsbury, the paragon of perspicuity. The mental habits
of Hobbes and Franklin in several points, especially in one of some
moment, assimilated. Indeed, making due allowance for soil and era,
history presents few trios more akin, upon the whole, than Jacob,
Hobbes, and Franklin; three labyrinth-minded, but plainspoken
Broadbrims, at once politicians and philosophers; keen observers of
the main chance; prudent courtiers; practical magians in linsey
woolsey.”
Craig mentions several scholars who debated Melville's intentions. One perhaps of interest to this discussion that I have not read is A. P. Martinich who he says in a footnote “is one of the few Hobbes scholars who recognizes the philosopher's presence in Melville's writing.” “Two Uses of Thomas Hobbes's Philosophy in Melville's The Confidence-Man,” ANQ 16, no. 3, 2003
Craig thinks Martinich underrates Hobbes's influence on Melville.
“Platonian Leviathan” was Ishmael's term which inspired Craig's research
“take high abstracted man alone; and he seems a wonder, a grandeur, and a woe.
But from the same point, take mankind in mass, and for the most part, they seem a mob of unnecessary duplicates, both contemporary and hereditary.” MD
