Intellectual honesty requires that one reflect on the contribution one’s theory makes to the class struggle, and acknowledge it openly. One does not … - Raymond Geuss

Diverting attention from the way in which certain beliefs, desires, attitudes, or values are the result of particular power relations, then, can be a sophisticated way of contributing to the maintenance of an ideology, and one that will be relatively immune to normal forms of empirical refutation. If I claim (falsely) that all human societies, or all human societies at a certain level of economic development, have a free market in health services, that is a claim that can be demonstrated to be false. On the other hand, if I focus your attention in a very intense way on the various different tariffs and pricing schema that doctors or hospitals or drug companies impose for their products and services, and if I become morally outraged by “excessive” costs some drug companies charge, discussing at great length the relative rates of profit in different sectors of the economy, and pressing the moral claims of patients, it is not at all obvious that anything I say may be straightforwardly “false”; after all, who knows what “excessive” means? However, by proceeding in this way I might well focus your attention on narrow issues of “just” pricing, turning it away from more pressing issues about the acceptance in some societies of the very existence of a free market for drugs and medical services. One can even argue that the more outraged I become about the excessive price, the more I obscure the underlying issue. One way, then, in which a political philosophy can be ideological is by presenting a relatively marginal issue as if it were central and essential.

The notion of being an “enlightened” person does not reduce simply to that of being a person who has highly developed cognitive abilities or disposes of a vast stock of knowledge; neither does it reduce to the idea of being a morally good or socially useful person. “Enlightenment” is not a value-free concept because it is connected with some idea of devoting persistent, focused attention to that which is genuinely important in human life, rather than to marginal or subsidiary phenomena, to drawing the “correct” conclusions from attending to these important features—whatever they are—and to embodying these conclusions concretely in one’s general way of living. It involves a certain amount of sheer knowledge, an ability to concentrate and reflect, inventiveness in restructuring one’s psychic, personal, and social habits; but to be enlightened is not to “have” any bit of doctrine, but to have been (re)structured in a certain way.

A major danger in using highly abstractive methods in political philosophy is that one will succeed merely in generalizing one’s own local prejudices and repackaging them as demands of reason. The study of history can help to counteract this natural human bias.
