In conclusion let me say for to-day in passing that the recommendation of the correct method for studying logic is not only an introduction, but, as I have already said, the subject matter of science itself. THIRD LETTER Dear Eugene: My task of teaching logic requires two things: a logician and a teacher. The last named capacity requires that I should clothe the subject in an attractive way. Permit me, therefore, to combine the didactic style with that of the story teller, and to relate at this point an episode from a novel of Gustav zu Putlitz: The organist of a certain village is lying on his deathbed. His last strength has been spent on the previous day in playing a hymn, and after its conclusion he was carried from the church in an unconscious state. He had played his masterpiece, but at the same time his last piece. A despised stage girl had accompanied him with a voice like that of a nightingale. But neither she nor the organ player had earned any applause from the stupid villagers. The old man looked around in his room, his eyes were first riveted on his faithful piano, his friend and companion through life. He extended his hand, but it sank down exhausted. He had not had the intention to touch the piano anyway. It was only like stretching out one's hand for a friend far away. Then he looked through the window trying to recollect what time of the day it was. And when he had taken in the situation, he turned to the girl kneeling at his feet. "Poor child," he began, "you were deeply disappointed yesterday. I felt very much hurt, when I first heard of it, but after that everything became clear to me while I heard the music all night, until a short while ago. Rejoice, my girl, at being reviled, for it is done for the sake of that sacred music, and it is an ecstasy, a blessing, to be martyred for one's music which is well worth all injuries. I did not fare any better all my life, and if I thank God for all the good he has done me until this hour, I also thank him first and most fervently for the gift of music which he bestowed on the world, and which he revealed to me most wonderfully in my most painful hours. "For my music I have starved and suffered all my life, and my gain was delicious, my reward celestial for this poor perishable stake.
