Vaccines are on everyone’s mind this year as we hope to move forward from the Coronavirus Pandemic, and I cannot help but think about today’s quote from Quassim Cassam’s book Vices of the Mind through a vaccine lens. While writing about ways to build and maintain epistemic virtues Cassam writes, “only the inculcation and cultivation of the ability to distinguish truth from lies can prevent our knowledge from being undermined by malevolent individuals and organizations that peddle falsehoods for their own political or economic ends.” In other words, there is no vaccine for lies and falsehoods, only the hard work of building the skills to recognize truth, narrative, and outright lies.
I am also reminded of a saying that Steven Pinker included in his book Enlightenment Now, “any jackass can knock down a barn, but it takes a carpenter to build one.” This quote comes to mind when I think about Cassam’s quote because building knowledge is hard, but spreading falsehoods is easy. Epistemic vices are easy, but epistemic virtues are hard.
Anyone can be closed-minded, anyone can use lies to try to better their own position, and anyone can be tricked by wishful thinking. It takes effort and concentration to be open-minded yet not gullible, to identify and counter lies, and to create and transmit knowledge for use by other people. The vast knowledge bases that humanity has built has taken years to develop, to weed out the inaccuracies, and to painstakingly hone in on ever more precise and accurate understandings of the universe. All this knowledge and information has taken incredible amounts of hard work by people dedicated to building such knowledge.
But any jackass can knock it all down. Anyone can come along and attack science, attack knowledge, spread misinformation and deliberately use disinformation to confuse and mislead people. Being an epistemic carpenter and building knowledge is hard, but being a conman and acting epistemically malevolent is easy.
The task for all of us is to think critically about our knowledge, about the systems and structures that have facilitated our knowledge growth and development as a species over time, and to do what we can to be more epistemically virtuous. Only by working hard to identify truth, to improve systems for creating accurate information, and to enhance knowledge highways to help people learn and transmit knowledge effectively can we continue to move forward. At any point we can chose to throw sand in the gears of knowledge, bringing the whole system down, or we can find ways to make it harder to gum up the knowledge machinery we have built. We must do the latter if we want to continue to grow, develop, and live peacefully rather than at the mercy of the epistemically malevolent. After all, there is no vaccine to cure us from lies and falsehoods.
