Below is the abstract of a paper (download here) that I published in the journal Disputatio. It is about virtue epistemology, an approach to knowledge acquisition and communication that might just be helpful in public discourse about science and pseudoscience.
It is no secret that we inhabit an increasingly irrational world, plagued by rampant pseudoscience, science denialism, post–truths and fake news. Or perhaps, human nature being what it is, we have always lived in such a world and we are now simply more keenly aware of it because of easy and widespread access to social media. Moreover, the stakes are higher, as pseudoscience in the form of the anti–vax movement imperils the lives of many, while climate change denialism literally risks a collapse of the human ecosystem. So how do we deal with the problem? How do we talk to otherwise perfectly reasonable and functional people who nevertheless espouse all sorts of nonsense — and vote accordingly? In this paper I will explore a couple of real life conversations among many that I have had with believers in pseudoscience, and then present and discuss virtue epistemology as one approach to ameliorate the problem. No silver bullets are available, unfortunately, but it is our intellectual and moral duty to keep, as Carl Sagan famously put it, the candle of reason lit even when surrounded by the darkness of unreason.
