I wrote a new thing for Areo Magazine. Here are some excerpts:

Science is first and foremost a cultural phenomenon. Individual scientists are riddled with biases and blind spots. Their views are subtly influenced by their sociopolitical contexts. The scope of their thought and investigation is substantially curtailed by the limits of extant knowledge and technology, some of which might well be faulty. But science is also a structured in a way that imbues it with peculiar properties. It can produce mistakes, but, to a degree unmatched by any other discipline, it is uniquely designed to identify those mistakes. Though imperfect, science is—by a considerable margin—the most powerful knowledge-gaining mechanism humans have ever devised.

But, even with a theory like general relativity, whose predictions have been tested and confirmed countless times, scientists still don’t claim to have discovered the final, unimpeachable description of space and time. In fact, most physicists will probably tell you that, at very vast or very tiny scales, the physics of general relativity is useless, if not entirely wrong. General relativity is one of the most successful theoretical frameworks ever devised, but it is not true beyond all doubt. There’s more reason to be confident in general relativity than there is to be confident about any of the comforting assumptions we use to get through the day—my spouse loves me, my job is secure, I’ll see my family again in the evening—but, in the strictest sense, it is not true beyond doubt.

Because postmodernists reject the idea of a final arbiter, such as a universally accessible and ultimately knowable reality against which claims can be evaluated, when postmodernists ask themselves are you sure? they can never really know the answer. Postmodernism lacks an anchor point for error correction. As a result, it is fundamentally illegitimate—and ultimately pointless—as an intellectual enterprise. It is, at best, a self-perpetuating indulgence, ostensibly doing the work scientific disciplines naturally do on their own.

In repudiating the notion that truths are fixed for eternity, postmodernism denies itself the capacity to course correct. Its students may pay lip service to the crude notion that some truths are better than others. But, without recourse to something universal and knowable outside their individual and social contexts, they’ll never be able to tell which truths those are.

As always, I encourage you to read the full piece here. And take some time to explore Areo, because they publish a lot of other interesting and insightful stuff.
