Like Bernard Mandeville, Archibald Campbell develops a profoundly egoistic conception of human psychology. However, Campbell attacks numerous points in Mandeville’s moral philosophy, in particular Mandeville’s treatment of self-love, the desire for esteem, and human nature in general as corrupt. He also criticises Mandeville’s corresponding insistence on self- denial and his rigorist conception of luxury. Campbell himself is subsequently attacked by Scottish orthodox Calvinists - not for his egoism, but for his optimism regarding postlapsarian human nature and self-love. This episode demonstrates that the debates on egoism in Mandeville should be seen in the context of the debates on postlapsarian human nature.
