"Anticipating Max Weber's argument about the symbiotic relationship between Protestantism and the spirit of capitalism, Brownson dismisses Protestantism as being too concerned with material goods and as engendering an ethic of unfettered individualism that results in social fragmentation and even, in the end, a 'spirit of lawlessness.'" Paul Giles, American Catholic Arts and Fictions: Culture, Ideology, Aesthetics (Cambridge University Press, 1992), p. 67. Giles refers to Brownson's "Protestantism in a Nutshell."
