@alraune When Godwin wrote Political Justice, he knew it would probably be inaccessible to a great many (it was so long that the government never bothered censoring it) so he wrote Caleb Williams as a companion piece, a novel that demonstrated those same ideas in a narrative format.
I think people really underestimate the power of fiction in conveying political ideas (least of all because we see it done badly a lot, like with Ayn Rand and Robert Heinlein)
