QUOTE : ...the ultimately possible attitudes toward life are irreconcilable, and hence their struggle can never be brought to a final conclusion. Thus it is necessary to make a decisive choice. Whether, under such conditions, science is a worth while 'vocation' for somebody, and whether science itself has an objectively valuable 'vocation' are again value judgments about which nothing can be said in the lecture-room. To affirm the value of science is a presupposition for teaching there. I personally by my very work answer in the affirmative, and I also do so from precisely the standpoint that hates intellectualism as the worst devil, as youth does today, or usually only fancies it does. In that case the word holds for these youths: 'Mind you, the devil is old; grow old to understand him.' This does not mean age in the sense of the birth certificate. It means that if one wishes to settle with this devil, one must not take flight before him as so many like to do nowadays. First of all, one has to see the devil's ways to the end in order to realize his power and his limitations.
