When a scientist is ahead of his times, it is often through misunderstanding of current, rather than intuition of future truth. In science there is never any error so gross that it won't one day, from some perspective, appear prophetic.
Interpretation
This quote highlights how scientists are often misinterpreted in their time, and their ideas may seem erroneous until future developments validate them.
Jean Rostand emphasizes that innovative scientific ideas may be misunderstood in their own time, reflecting more of a contemporary misunderstanding rather than an actual error of intuition about future truths. He suggests that what appears to be incorrect or speculative today could later be recognized as visionary. This perspective invites us to appreciate the complexity of scientific progress and the role of societal context in shaping our understanding of truth.
In practice
In a lecture about scientific theories, you could use this quote to illustrate how groundbreaking ideas are often misunderstood.
If a given scientist had not made a given discovery, someone else would have done so a little later. Johann Mendel dies unknown after having discovered the laws of heredity: thirty-five years later, three men rediscover them. But the book that is not written will never be written. The premature death of a great scientist delays humanity; that of a great writer deprives it.
Certain brief sentences are peerless in their ability to give one the feeling that nothing remains to be said.
My pessimism extends to the point of even suspecting the sincerity of other pessimists.
We spend our time envying people whom we wouldn't wish to be.
Stupidity, outrage, vanity, cruelty, iniquity, bad faith, falsehood - we fail to see the whole array when it is facing in the same direction as we.
A few great minds are enough to endow humanity with monstrous power, but a few great hearts are not enough to make us worthy of using it.
Any work of science, no matter what its point of departure, cannot become fully convincing until it crosses the boundary between the theoretical and the experimental: Experimentation must give way to argument, and argument must have recourse to experimentation.
'Goals' and 'caps' on carbon emissions are practically worthless, if coal emissions continue, because of the exceedingly long lifetime of carbon dioxide in the air.
So if the worth of the arts were measured by the matter with which they deal, this art-which some call astronomy, others astrology, and many of the ancients the consummation of mathematics-would be by far the most outstanding. This art which is as it were the head of all the liberal arts and the one most worthy of a free man leans upon nearly all the other branches of mathe matics. Arithmetic, geometry, optics, geodesy, mechanics, and whatever others, all offer themselves in its service.
I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection.
To learn more about science, turn off your electronic device and go outside and look around a bit. Nature is calling you. Go on. The internet will still be here.
One lesson astronomy tells us is that we're a tiny mote in a hostile void, and help is too far away.
