The advantage of the emotions is that they lead us astray, and the advantage of Science is that it is not emotional.
We feel that even if all possible scientific questions be answered, the problems of life have still not been touched at all.[Wir fühlen, dass selbst, wenn alle möglichen wissenschaftlichen Fragen beantwortet sind, unsere Lebensprobleme noch gar nicht berührt sind.]
True science teaches, above all, to doubt and to be ignorant; advocacy neither doubts nor believes that it does not know. It requires a solution.[La verdadera ciencia enseña, ante todo, a dudar y a ignorar; la abogacía ni duda ni cree que ignora. Necesita de una solución.]
To be independent of public opinion is the first formal condition of achieving anything great or rational whether in life or in science.
This violent reaction on the recent development of modern physics can only be understood when one realizes that here the foundations of physics have started moving; and that this motion has caused the feeling that the ground would be cut from science.
