You know the shtick by now–or at least, twitterers and tweeters do. Every few weeks, Neil deGrasse Tyson, one of America’s most popular public ‘scientific’ intellectuals, decides that it is time to describe some social construct in scientific language to show how ‘arbitrary’ and ‘made-up’ it all is–compared to the sheer factitude, the amazing reality-grounded non-arbitrariness of scientific knowledge. Consider for instance, this latest gem, now predictably provoking ridicule from those who found its issuance predictable and tired:
Not that anybody’s asked, but New Years Day on the Gregorian Calendar is a cosmically arbitrary event, carrying no Astronomical significance at all.
A week earlier, Tyson had tweeted:
Merry Christmas to the world’s 2.5 billion Christians. And to the remaining 5 billion people, including Muslims Atheists Hindus Buddhists Animists & Jews, Happy Monday.
Tyson, I think, imagines that he is bringing science to the masses; that he is dispelling the ignorance cast by the veil of imprecise, arbitrary, subjective language that ‘ordinary folk’ use by directing their attention to scientific language, which when used, shows how ridiculous those ‘ordinary folk’ affectations are. Your birthday? Just a date. That date? A ‘cosmically arbitrary event.’ Your child’s laughter? Just sound waves colliding with your eardrum. That friendly smile beamed at you by your school mate? Just facial muscles being stretched. And so on. It’s really easy; almost mechanical. I could, if I wanted, set up a bot-run Neil deGrasse Tyson Parody account on Twitter, and just issue these every once in a while. Easy pickings.
Does Tyson imagine that he is engaging in some form ‘scientific communication’ here, bringing science to the masses? Does he imagined he is introducing greater precision and fidelity to truth in our everyday conversation and discourse, cleaning up the degraded Augean stables of internet chatter? He might think so, but what Tyson is actually engaged in is displaying the perils of facile reductionism and the scientism it invariably accompanies and embellishes; anything can be redescribed in scientific language but that does not mean such redescription is necessary or desirable or even moderately useful. All too often such redescription results in not talking about the ‘same thing’ any more. (All that great literature? Just ink on paper! You know, a chemical pigment on a piece of treated wood pulp.)
There are many ways of talking about the world; science is one of them. Science lets us do many things; other ways of talking about the world let us other do things. Scientific language is a tool; it lets us solve some problems really well; other languages–like those of poetry, psychology, literature, legal theory–help us solve others. The views they introduce of this world show us many things; different objects appear in different views depending on the language adopted. As a result, we are ‘multi-scopic’ creatures; at any time, we entertain multiple perspectives on this world and work with them, shifting between each as my wants and needs require. To figure out what clothes to wear today, I consulted the resources of meteorology; in order to get a fellow human being to come to my aid, I used elementary folk psychology, not neuroscience; to crack a joke and break the ice with co-workers, I relied on humor which deployed imaginary entities. Different tasks; different languages; different tools; it is the basis of the pragmatic attitude, which underwrites the science that Tyson claims to revere.
Tyson has famously dissed philosophy of science and just philosophy in general; his tweeting shows that he would greatly benefit from a philosophy class or two himself.
