Three reasons to invest in science

Space research embodies all reasons to invest in science, at least until you are hit by a meteor.

Space research embodies all reasons to invest in science – knowledge, technique, employment – at least until you are hit by a meteor. (Scene from Gravity.)

As scientists, we have constantly to justify ourselves. People ask what is our research useful for. It is a fair question – as most of time public funds are involved – but it is a poor question. Science is more than being useful for something. Here are three reasons to invest in science, even “useless” science.   

My resolution for this year is not to read any text with a counting number for a title. I can’t help myself, I have to start the year with such a lame title. But lazy as I am, I will only count to three: the three reasons to invest in science.

1. Science is the theory of the real

The first and most obvious reason to invest in science is that science is the theory of the real. (I borrowed this expression from Heidegger, but the reference ends here.) Science produces the concepts and discourses with which secular society interprets the world. It is science that allows us to tell that the world exists at 13.7 billion years, that all beings evolved from a common ancestor, that our bodies are made of atoms and that our minds are not ghosts manipulating puppets.

Romantic people often complain that science takes the beauty away from whatever it touches. It is a misconception that holds only if you mistake ignorance for beauty. Look, for instance, at the amazing darkness of the night sky. To know that it is dark because the universe is expanding only adds to our feeling of beauty and astonishment, not the opposite.

But I confess I am tired of the copy-and-paste short-sentences collection of scientists in the Discovery Channel. I miss the magnificence of Carl Sagan’s Cosmos under the sound of Bach, Vivaldi and Vangelis.

2. Science is the potential of the technique

The second reason to invest in science – less romantic, but not less important – is that science is the potential of the technique. Science obviously connects itself to all social sectors. It has been a reservoir of ideas, concepts and practices feeding industry, finances, services, medicine, food production, education, …, you name it.

As the potential of the technique, science has made possible all revolutions that raised our life expectancy 40 years in the last century, disproved generation after generation of Neo-Malthusians, and, on a dark note, brought us to the edge of self-annihilation a few times.  

But as scientists we do not need to lie (as we often do in our proposals and paper introductions): when people ask what your research is useful for, the answer (most of time) is simply “I don’t know”. Einstein was not thinking of Blu-Ray players when he developed the theory of the laser. In the other way around, Planck had no idea that he would trigger a major revolution in basic physics, when he was looking for more efficient light bulbs. Science works in mysterious ways…

3. Science is qualified consumption

Finally, the third reason to invest in science: science is qualified consumption. The scientific enterprise, in every aspect – education of new scientists, set up of labs, organization of conferences, technical publications, register of patents, journalistic popularization – involve a large number of qualified workers: scientists, technicians, editors, journalists, bureaucrats.

If the other two reasons are just obvious, this third one is often neglected in spite of its importance. Every penny invested in science immediately returns to society under the form of qualified consumption. And these are good news to the pragmatics: investing in science, even the most pure and abstract, create jobs, good jobs in the whole productive chain.

  1. Very interesting this new article, trying to make your readers understand the importance of science in every sector of human life. No doubt that there are more than a century, many great scientists have helped in the evolution of a society more comfortable, safe and happy, always searching to discover new products and conditions for the progress of mankind.
