Studies and Exercises in Formal Logic

The book offers a systematic manual of formal logic, combining exposition and exercises. Part I examines terms, extension and intension, connotation, and classification of names; Part II analyzes judgment and propositions, modality, conditional and existential import; Part III develops syllogistic methods including indirect reduction and inference characteristics; Part IV generalizes logical processes to complex, non-symbolic inferences and offers techniques intended to achieve similar ends to symbolic systems. Euler-style diagrams, appendices on fundamental laws and division, and numerous worked and unworked problems support both theory and practice.
