“…Finally, there were a number of articles that did not fall within any of the above categories. These articles were largely descriptive in nature and included philosophical (e.g., Ladd-Franklin, 1889), pedagogical (e.g., Williams, 1892), and historical discussions (e.g., Patrick, 1888), as well as methodological discussions (e.g., Jastrow, 1888) and anthropological descriptions of particular groups (e.g., Edwards, 1889).…”

In this article, we present the results of an exploratory digital analysis of the contents of the two journals founded in the late 19th century by American psychologist G. Stanley Hall. Using the methods of the increasingly popular digital humanities, some key attributes of the American Journal of Psychology (AJP) and the Pedagogical Seminary (PS) are identified. Our analysis reaffirms some of Hall's explicit aims for the two periodicals, while also revealing a number of other features of the journals, as well as of the people who published within their pages, the methodologies they employed, and the institutions at which they worked. Notably, despite Hall's intent that his psychological journal be strictly an outlet for scientific research, the journal-like its sister pedagogically focused publication-included an array of methodologically diverse research. The multiplicity of research styles that characterize the content of Hall's journals in their initial years is, in part, a consequence of individual researchers at times crossing methodological lines and producing a diverse body of research. Along with such variety within each periodical, it is evident that the line between content appropriate to one periodical rather than the other was fluid rather than absolute. The full results of this digitally informed analysis of Hall's two journals suggest a number of novel avenues for future research and demonstrate the utility of digital methods as applied to the history of psychology.

“…Mathematically inclined logicians began to apply algebraic methods to syllogistic logic. One of the major figures in this tradition was Christine Ladd-Franklin, who reconceptualised Aristotelian logic as a calculus based on the relation of exclusion, effectively a NAND-operator (Ladd, 1883;Ladd-Franklin, 1889, 1912; see also Uckelman, 2021;Janssen-Lauret, in press-a). Ladd-Franklin in addition had an excellent eye for natural-language illustrations of logical principles used in everyday reasoning: 'When I said to my little girl, "I will take you down town this afternoon if you are good," she said "And only?"…”

Susan Stebbing (1885–1943), the UK's first female professor of philosophy, was a key figure in the development of analytic philosophy. Stebbing wrote the world's first accessible book on the new polyadic logic and its philosophy. She made major contributions to the philosophy of science, metaphysics, philosophical logic, critical thinking and applied philosophy. Nonetheless she has remained largely neglected by historians of analytic philosophy. This Element provides a thorough yet accessible overview of Stebbing's positive, original contributions, including her solution to the paradox of analysis, her account of the relation of sense data to physical objects, and her anti- idealist interpretation of the new Einsteinian physics. Stebbing's innovative work in these and other areas helped move analytic philosophy from its early phase to its middle period.

“…[Ladd Franklin(1889), p. 543] The simplest example of this type of manipulation is found in the syllogism-three propositions, three distinct terms, each occurring twice, and one term which is eliminated from the premises when generating the conclusion. The difficulty in Boole's solution is determining what is the term (or terms) to be eliminated; once the term is identified, 'an ordinary syllogism would suffice to put it to flight' [Ladd Franklin(1889) given certain combinations inconsistent with conditions to determine those conditions. [Jevons(1880), p. 252] The solution that Jevons provides 'consists in inventing laws and trying whether their results agree with those before us' [Jevons(1880), p. 252].…”
