Hey, check this out, you might find it interesting. From Parenti’s Contrary Notions:

If what passes for objectivity is little more than a culturally defined self-confirming symbolic environment, and if real objectivity—whatever that might be—is unattainable, then it would seem that we are left in the grip of a subjectivism in which one paradigm is about as reliable (or unreliable) as another. And we are faced with the unhappy conclusion that the search for social truth involves little more than choosing from a variety of illusory symbolic configurations. As David Hume argued over two centuries ago, the problem of what constitutes reality in our images can never be resolved since our images can only be compared with other images and never with reality itself.
