Two Philosophical Arguments Against 'New Left' Politics

The Enlightenment liberal tradition provides the most apparent arguments to rebut the postmodern critical theory worldview. That free speech is conducive to understanding the objective truth, and that understanding the truth is necessary for practical progress, is itself a self-evident truth that is provable by the study of history alone. It is for this reason that we must always stand firm for free speech. Also, there are good reasons why we should require objective evidence before we can agree that claims being made are sound. Postmodern critical theory's insistence that society is made up of interlocking systems of oppression simply doesn't meet this standard, and thus should be rejected. Besides, viewing society as being made up of interlocking systems of oppression is simply counterproductive, if we want to bring people together to resolve society's most sensitive conflicts, by finding solutions that would be satisfactory for every party. 

The conservative philosophical tradition, going back to thinkers like Edmund Burke, also provide important arguments against the postmodern critical theory worldview. It speaks to how the top-down, inorganic imposition of social change, driven by abstract philosophical doctrine, can be harmful to freedom, and also make things worse in unexpected ways in reality. This is why change must be gradual, rooted in practical need rather than abstract philosophy, and implemented in a way that respects society's long-standing values as much as possible. This lesson is one that progressives would do well to learn. This, in turn, is why I have long argued that the philosophical insights of the conservative cannon should be re-integrated into progressive thinking, and this would make for a good foundation for a sustainable reformist politics. Note that the conservative philosophical tradition is very different from what is wrongly called 'conservative' politics in the contemporary West, which is clearly more authoritarian-reactionary than conservative. True conservative philosophy would lead to a moderate reformist politics.
