Enlightened Self-Interest and Prudential Self-Interest

'Enlightened' Self-Interest can be distinguished from what is sometimes called 'Prudential' Self-Interest. While according to the former, one's own Good is either a means to or a part of the General Good, according to the latter, the achievement of the General Good benefits oneself, and, hence, is to be promoted as a means to it. Both main versions of Utilitarianism are examples of the former, while the latter follows from the premise, advocated by e. g. Hume, that the role of Reason in behavior is to calculate the best means to one's satisfaction. In contrast, Smith vacillates between the two concepts of Self-Interest-- the phrase 'wealth of nations' expresses the 'enlightened' variety, while some passages reflect Hume's influence. Contemporary Capitalist discourse about 'Enlightened Self-Interest' is typically similarly casual in that respect.
