Dr. Nicolai, professor of physiology at Berlin University and physician to the imperial household, found himself, when the war broke out, in the very focus of the madness which seized the flower of his nation. Not merely did he refuse to share that madness. Yet more daring, he openly resisted it. In reply to the manifesto of the 93 intellectuals, published in the beginning of October, 1914, he wrote a counter-manifesto, _An Appeal to Europeans_, which was endorsed by two other distinguished professors at the university of Berlin, Albert Einstein, the celebrated physicist, and Wilhelm Foerster, president of the international bureau of weights and measures, the father of Professor F. W. Foerster. This manifesto was not published, for Nicolai was unable to collect a sufficient number of signatures. In the summer term of 1915 he incorporated it in the opening of a series of lectures he planned to deliver upon the war. Thus, for the fulfilment of what he deemed his duty as an honest thinker, he deliberately risked his social position, his academic career, his distinctions, his comfort, and his friendships. He was arrested, and was interned in Graudenz fortress. There, unaided, and almost without books, he penned his admirable _Biology of War_, and managed to have the manuscript sent to Switzerland, where the first German edition has just been published. The circumstances in which the book was written have an atmosphere of mystery and heroism recalling that of the days when the Holy Inquisition was endeavouring to stifle the thought of Galileo. In the modern world, the Inquisition of the United States of Europe and America is no less crushing than was the Holy Inquisition of old. But Nicolai, firmer of spirit than Galileo, has refused to recant. Last month (September, 1917), the journals of German Switzerland announced that he had been once more brought to trial, and had been sentenced to five months' imprisonment by the Danzig court-martial. Thus again does force manifest its ludicrous weakness, for its unjust decrees merely help to raise a statue to the man whom force would fain strike down. * * * * *
