Jerome Huyler and Michael P. Zuckert approach Locke in the broader context of his oeuvre and historical influence. Locke is situated within changing religious, philosophical, scientific, and political dimensions of 17th century England. Objecting to the use of the contemporary concept of economic man to describe Locke's view of human nature, Huyler emphases the "virtue of industriousness" of Locke's Protestant England. Productive work is man's earthly function or calling, ordained by God and required by self-preservation. The government's protection of property rights insures that the results of industry, i.e. "fruits of one’s labor", are secure. Locke's prohibition of ill-gotten gains, whether for well-connected gentry or the profligate, is not a lack of Locke's foresight to the problems in the latter stages of liberalism but an application of equal protection of the law to every individual.
