Last and First Men from WHEE has a discussion of Fukuyama and his ‘end of history’ thesis: scroll to the end of the chapter, and check out the references in the footnotes.
Hegel didn’t actually use the phrase ‘end of history’ and its emergence in his thought requires careful scholarly study.
Here are the references from one footnote (Jon Stewart’s book is emphasized):
Francis Fukuyama, The End of History and the Last Man (New York: The Free Press, 1992). Jon Stewart, The Hegel Myths and Legends (Evanston, Il.: Northwestern University Press, 1996). Fukuyama ’s interpretation is influenced by the works of the philosopher Alexander Kojeve, Introduction to the Reading of Hegel (1969). Cf. also, Shadia Drury, Alexander Kojeve, The Roots of Postmodern Politics (New York: St. Martin’s, 1994). Cf. also After History? Francis Fukuyama and his Critics, Timothy Burns (ed), (Lanham, Md.: Rowman & Littlefield, 1994). Cf. “The Tower of Babel Rebuilt”, Peter Fenves traces the Kantian origins of the ‘end of history’ idea and the reservations of Kant in his “An Old Question Asked Anew”. George Kelly, Idealism, Politics, and History (New York: Cambridge University Press, 1969). For a discussion of Kojeve on Kant and Hegel, cf. Patrick Riley, Kant’s Political Philosophy (Totowa, New Jersey: Rowman and Allanheld, 1983), Bhikhu Parekh, Marx’s Theory of Ideology (Baltimore: The John Hopkins University Press, 1982).
