 Stebbing’s first significant work, which established her reputation, was A Modern Introduction to Logic. First published in 1930, it was revised in 1933, and might justly be regarded as the first textbook of analytic philosophy: it went through several editions and was still being reprinted in the early 1960s. Its main aim was to introduce readers to the developments in logic that had taken place over the previous five decades, though she leads into this through discussion of traditional Aristotelian logic. Its title was “A Modern Introduction to Logic”, not “An Introduction to Modern Logic”. Divided into three parts, the first deals with topics that are now familiar in analytic philosophy, such as names and descriptions, logical form, the theory of descriptions, inference and implication, as well as offering an account of syllogistic theory. The second deals with scientific methodology, covering induction and causality, in particular. The third discusses definition, abstraction, and the nature and historical development of logic.
