Why “Useless” Knowledge Still Has Value

Why “Useless” Knowledge Still Has Value

We often think that knowledge needs to be practical. Indeed, that’s why we have phrases like “Knowledge is power” since it can help get what we want. But sometimes, knowledge isn’t just instrumental — it can have tremendous inherent beauty, even if it is totally useless.

We saw that recently with the discovery of gravitational waves through the Laser Interferometer Gravitational-Wave Observatory (LIGO), which confirmed Einstein’s theory of general relativity. But I would venture to guess that only a small handful of people actually truly understood what was going on, even as it was trumpeted all over the news and social media. Instead, most of us did what the humor site Cracked suggested: “Excitedly tweet this to imply you understand theoretical physics.”

So clearly, knowledge doesn’t just have to be “useful” — it can spark curiosity for its own sake. After all, unless you live in the world of astrophysics, your day-to-day life after the discovery of gravitational waves wasn’t fundamentally different from what it was before. But it captured people’s imaginations, and that was enough to make front-page headlines.

The New York Times’ Editorial Board made a similar argument:

[D]oes science, or knowledge, really need a justification? It is hard to imagine that any man or woman since the dawn of intelligent life has not gazed out at the sky on a moonless night, wondering how it came to be and what is our place in this vast and wondrous firmament. And each time science has advanced our understanding of those countless dots of light, it has uncovered more mysteries, more questions. The curiosity of our species knows no bounds; more remarkably, neither does our capacity for satisfying it. And that is truly wonderful in itself, even if it doesn’t lead to a better toaster.

In Jewish tradition, too, there is an idea that learning is its own reward. We don’t need to gain something extra when we study; the studying itself is the point. And that shift can help understand both religion and science in a different way – not as competing truths, but as sources of beauty.
