Synopsis
In the form of the proportion, the copula is made as abftracl: as the terms: or is considered as obeying only thofe conditions which are neceflary to inference. Every name is treated in connection with its contrary or contradictory name; the diftinction between thefe words not being made, and others fupplied in confequence. Eight really feparable forms of predication are thus ob tained, between any two names :the eight of the common fyftem amounting only to fix, when, as throughout my work, the two forms of a convertible proportion are confidered as identical. The complex proportion is introduced, confirming in the coexiftence of two fimple ones. The theory of the fyllogifm of complex propofitions is made to precede that of the fimple or ordinary fyllogifm ;which laft is deduced from it. I have only ufed the word complex, was already appropriated (fee page 85).

Formal Logic or the Calculus of Inference, Necessary (Classic Reprint)
Print on DemandSeller: Forgotten Books, London, United Kingdom
Seller rating 5 out of 5 stars
Paperback. Condition: New. Print on Demand. This book presents a unique and comprehensive system of logic, going beyond the traditional Aristotelian framework. The author delves into the structure of propositions, examining how they function in inferences, and explores the various forms of predication, expanding the standard eight to a more nuanced set of eight. The book then introduces the concept of the complex proposition, a combination of two simple ones, and uses this to develop a theory of syllogisms for complex propositions. This approach leads to a remarkable increase in the number of valid syllogistic forms to thirty-two, all connected by intricate rules of relation. The author further challenges traditional logic by introducing a numerical theory of probability, arguing that it is an integral part of logical reasoning, rather than an extralogical concept. By examining the degrees of belief and knowledge, the author challenges the notion of absolute truth, suggesting that logic should consider the impact of partial belief on the validity of inferences. This book offers a groundbreaking exploration of logic, challenging established conventions and expanding the scope of the discipline. It provides a fresh perspective on how we reason and draw conclusions, highlighting the inherent complexities of knowledge and belief.
