Very rare early offprint by the pioneering American woman logician, published while she was a graduate student under C.S. Peirce, who was to become her lifelong friend. In 1882 she married Fabian Franklin, a member of the mathematics faculty at Johns Hopkins and her former classmate. 'Christine Ladd (1847-1930) received her BA in 1869 and the LLD in 1887 from Vassar College. After teaching science and mathematics in secondary schools for several years, she undertook graduate study at Johns Hopkins University, admitted under special circumstances because the university was not open to women. Although she qualified for the PhD degree in 1882 it was withheld at that time because of her gender, but granted more than four decades later when the university celebrated its semicentennial in 1926. By then Ladd had attained an enviable reputation in both logic and psychology. She was the pioneer American woman in those two fields as well as in mathematics. Her first [sic] paper on logic (1883) detailed her modification of the logical algebra of Boole and proposed that syllogistic reasoning might be reduced to a single formula, the “inconsistent triad” or "antilogism," whereby any two of the three propositions will yield a valid contradiction of the third. Josiah Royce referred to this as "the definitive solution of the problem of the reduction of syllogisms" and further commented that "it is rather remarkable that the crowning activity in a field worked over since the days of Aristotle should be the achievement of an American woman"' (Elizabeth Scarborough in The Dictionary of Modern American Philosophers). In 1948, Bertrand Russell wrote: 'I once received a letter from an eminent logician, Mrs. Christine Ladd-Franklin, saying that she was a solipsist, and was surprised that there were no others. Coming from a logician and a solipsist, her surprise surprised me' (Human Knowledge: Its Scope and Limits, p. 180). PHYSICAL DESCRIPTION: 4to, 17 pp., original printed wrappers, a little dusty and with repairs to lower corners, internally very clean. N° de ref. de la librería ABE-13411579773
