These ethical positions have corresponding epistemologies—philosophies for obtaining knowledge. The objectivist epistemology is associated with the utilitarian ethic; in general, it is used to acquire knowledge that can be externally verified (intersubjective agreement) through publicly exposed methods and data. The subjectivist epistemology is associated with the intuitionist/pluralist ethic and is used to acquire new knowledge based on existing personal knowledge, as well as experiences that are (explicit) or are not (tacit) available for public inspection. House then divides each epistemological approach into two main political perspectives. Firstly, approaches can take an elite perspective, focusing on the interests of managers and professionals; or they also can take a mass perspective, focusing on consumers and participatory approaches.
