“The task is…not so much to see what no one has yet seen; but to think what nobody has yet thought, about that which everybody sees.”And there are variations on this, such as "Discovery consists of seeing what everybody has seen and thinking what nobody has thought," "Genius consists of..." and "Research is...."
But today, when I was trying to find out where Schrödinger said or wrote this, I found that he doesn't seem to have written it at all.
There are hundreds (about 680) of Google results that attribute it to Schrödinger. Wikiquote says Schrodinger said it, and so does the author Brian Greene.
But googling around I began to see attributions to the philosopher Schopenhauer, and then to the physiologist Albert Szent-Györgyi.
So who gets credit? Schopenhauer, I believe. This site, devoted to investigating quotes, written by a guy who says he wrote a best selling book on such investigations, finds
In 1851 Arthur Schopenhauer published a two volume work written in German titled “Parerga und Paralipomena” which contained a collection of long essays together with a series of short numbered passages. The piece numbered 76 included the following...."I'm not going to go look up the original reference -- I doubt I'd find it in the original German anyway, which I can't read anyway. And while I don't agree that it takes so much more to be a philosopher than a physicist(!) -- at least I can kind of understand the physicists -- this is some good evidence that the words, or something essentially identical to them, came from Schopenhauer and not Schrödinger. Poor Schopenhauer only gets about 25 Google returns for it.
Daher ist die Aufgabe nicht sowohl zu sehen was noch keiner gesehen hat, als bei Dem was Jeder sieht, zu denken was noch Keiner gedacht hat. Darum auch gehört so sehr viel mehr dazu, ein Philosoph als ein Physiker zu seyn.
Here are two possible translations into English:
1) So the problem is not so much to see what nobody has yet seen, as to think what nobody has yet thought concerning that which everybody sees. Also for this reason, it takes so very much more to be a philosopher than a physicist.
2) Therefore the problem is not so much, to see what nobody has yet seen, but rather to think concerning that which everybody sees, what nobody has yet thought. For this reason, it also takes very much more to be a philosopher than a physicist.
So now I have to go all over the Web correcting everyone who said it was Schrödinger. I'll return to blogging in 2020 when this task has been finished.
