Logic. General Theory of Proof
6.99 €
What is true and what is false? What is the difference between causal and immediate inferences? Why sometimes a true conclusion follows from an erroneous inference, and where were the medieval theologians wrong? This book by Sergei Innokentyevich Povarnin, a major expert in logic, was first published in 1916. Thanks to the consistent and structured presentation of the material, this work has been well-deservedly recognized not only by contemporaries, but also by subsequent generations of readers studying this discipline. The author discusses in detail the most important issues of theoretical logic and builds an elementary theory of proofs. The book contains an essay on the theory of logical series and intra-order inferences. Along with revising such concepts as the composition of judgments and the presentation of types of inferences, the author clarifies established but imperfect terminology. The book will be useful to all those who study logic as a scientific discipline and are interested in the laws of human thinking.
