The constant misunderstandings with his wife had increased to such a point that both felt a separation desirable. Married people do not separate on slight excuse--they go because they must. That Comte thought much more of the lady when they were several hundred miles apart than when they were together, there is no doubt. He wrote to her at regular intervals, one-half of his income was religiously sent to her, and he practised the most painstaking economy in order that he might feel that she was provided for. One letter, especially, to his wife reveals a side of Comte's nature that shows he had the instinct of a true teacher. He says, "I hardly dare disclose the sweet and softened feeling that comes over me when I find a scholar whose heart is thoroughly in his work." The Positive Philosophy was taken up by John Stuart Mill, who wrote a fine essay on it. It was Mill who introduced the work to Harriet Martineau. Mr. and Mrs. Mill had intended to translate and condense the philosophy of Comte for English readers, but when Miss Martineau expressed her intention of attempting the task, they relinquished the idea, but backed her up in her efforts. Miss Martineau condensed the six volumes into two, and what is most strange, Comte thought so well of the work that he wrote a glowing acknowledgment of it. The Martineaus were of good old Huguenot stock, and the French language came easy to Harriet. For the plain people of France she had a profound regard, and being sort of a revolutionary by prenatal instincts, Comte's work from the start appealed to her. James Martineau had such a bristling personality--being very much like his sister Harriet--that when this sister wrote a review of a volume of his sermons, showing the fatuity and foolishness of the reasoning, and calling attention to much bad grammar, the good man cut her off with a shilling--"which he will have to borrow," said Harriet. James hugged the idea to his death that his sister had insulted his genius--"But I forgive her," he said, which remark proves that he hadn't, for if he had, he would not have thought to mention the matter. James Martineau was a great man, but if he had been just a little greater he would have taken a profound pride in a sister who was so sharp a shooter that she could puncture his balloon. James Martineau was a theologian; Harriet was a Positivist. But Positivity had a lure for him, and so there is a long review, penned largely with aqua fortis, on Miss Martineau's translation, done by her brother for the "Edinburgh Review," wherein Harriet is not once mentioned. When Robert Ingersoll's wife would occasionally, under great stress of the servant-girl problem, break over a bit, as good women will, and say things, Robert would remark, "Gently, my dear, gently--I fear me you haven't yet gotten rid of all your Christian virtues."
