The Liberty of Doctrine--à propos of the Guntbel Case Academic chairs are many, but wise and noble teachers are few; lecture-rooms are numerous and large, but the number of young people who genuinely thirst after truth and justice is small. Nature scatters her common wares with a lavish hand, but the choice sort she produces but seldom. We all know that, so why complain? Was it not ever thus and will it not ever thus remain? Certainly, and one must take what Nature gives as one finds it. But there is also such a thing as a spirit of the times, an attitude of mind characteristic of a particular generation, which is pa**ed on from individual to individual and gives a society its particular tone. Each of us has to do his little bit towards transforming this spirit of the times. Compare the spirit which animated the youth in our universities a hundred years ago with that prevailing to-day. They had faith in the amelioration of human society, respect for every honest opinion, the tolerance for which our cla**ics had lived and fought. In those days men strove for a larger political unity, which at that time was called Germany. It was the students and the teachers at the universities who kept these ideals alive. Today also there is an urge towards social progress, towards tolerance and freedom of thought, towards a larger political unity, which we to-day call Europe. But the students at our universities have ceased as completely as their teachers to enshrine the hopes and ideals of the nation. Anyone who looks at our times coolly and dispa**ionately must admit this. We are a**embled to-day to take stock of ourselves. The external reason for this meeting is the Gumbel case. This apostle of justice has written about unexpiated political crimes with devoted industry, high courage, and exemplary fairness, and has done the community a signal service by his books. And this is the man whom the students, and a good many of the staff, of his university are to-day doing their best to expel. Political pa**ion cannot be allowed to go to such lengths. I am convinced that every man who reads Herr Gumbel's books with an open mind will get the same impression from them as I have. Men like him are needed if we are ever to build up a healthy political society. Let every man judge according to his own standards, by what he has himself read, not by what others tell him. If that happens, this Gumbel case, after an unedifying beginning, may still do good.
