Studies and Exercises in Formal Logic

A thorough introduction to formal logic, this work walks the listener through the foundations of terms, propositions, and syllogisms. The author revises classic material with fresh definitions—such as a new take on “connotative names”—and clarifies long‑standing debates about negative and modal statements. Euler diagrams appear frequently, offering visual help that makes abstract relationships easier to grasp. The revised chapters also expand discussions of conditional and hypothetical propositions, giving a more nuanced view of how judgments import meaning.

Beyond the theory, the book supplies a wealth of worked‑out problems and open exercises, inviting listeners to test their own reasoning skills. A whole section is devoted to the systematic handling of complex inferences, presenting methods that rival symbolic approaches while staying in ordinary language. The final part even outlines a reliable technique for tackling the “inverse problem,” a classic challenge that has puzzled logicians since the nineteenth century.
