Creating a “Fourth Culture” of Knowledge: Jonah Lehrer on Why Science and Art Need Each Other
By Maria Popova
One of my favorite books of all time is Jonah Lehrer’s Proust Was a Neuroscientist, which tells the story of how a handful of iconic creators each discovered an essential truth about the mind long before modern science was able to label and pinpoint it — for instance, George Eliot detected neuroplasticity, Gertrude Stein uncovered the deep structure of language, Cézanne fathomed how vision works, and Proust demonstrated the imperfections of memory. I was recently reminded of this powerful passage, in which Lehrer makes a case for the extraordinary importance of the cross-pollination of disciplines, the essence of Brain Pickings’ founding philosophy, particularly of art and science — a convergence Lehrer calls a “fourth culture” that empowers us to “freely transplant knowledge between the sciences and the humanities, and focus on connecting the reductionist fact to our actual experience.”
We now know enough to know that we will never know everything. This is why we need art: it teaches us how to live with mystery. Only the artist can explore the ineffable without offering us an answer, for sometimes there is no answer. John Keats called this romantic impulse ‘negative capability.’ He said that certain poets, like Shakespeare, had ‘the ability to remain in uncertainties, mysteries, doubts, without any irritable reaching after fact and reason.’ Keats realized that just because something can’t be solved, or reduced into the laws of physics, doesn’t mean it isn’t real. When we venture beyond the edge of our knowledge, all we have is art.
But before we can get a fourth culture, our two existing cultures must modify their habits. First of all, the humanities must sincerely engage with the sciences. Henry James defined the writer as someone on whom nothing is lost; artists must heed his call and not ignore science’s inspiring descriptions of reality. Every humanist should read Nature.
At the same time, the sciences must recognize that their truths are not the only truths. No knowledge has a monopoly on knowledge. That simple idea will be the starting premise of any fourth culture. As Karl Popper, an eminent defender of science, wrote, ‘It is imperative that we give up the idea of ultimate sources of knowledge, and admit that all knowledge is human; that it is mixed with our errors, our prejudices, our dreams, and our hopes; that all we can do is to grope for truth even though it is beyond our reach. There is no authority beyond the reach of criticism.”
Lehrer’s new book, Imagine: How Creativity Works, comes out later this month.
