The book is a study of a number of systems, their methods, their rela- tions, their differences. In pursuit of this goal, a chapter explaining basic concepts of modern logic together with the truth-table techniques of definition and proof is first set out. In Chapter 2 a kind of ur-Iogic is built up and deductions are made on the basis of its axioms and rules. This axiom system, resembling a propositional system of Hilbert and Ber- nays, is called P +, since it is a positive logic, i. e., a logic devoid of nega- tion. This system serves as a basis upon which a variety of further sys- tems are constructed, including, among others, a full classical proposi- tional calculus, an intuitionistic system, a minimum propositional calcu- lus, a system equivalent to that of F. B. Fitch (Chapters 3 and 6). These are developed as axiomatic systems. By means of adding independent axioms to the basic system P +, the notions of independence both for primitive functors and for axiom sets are discussed, the axiom sets for a number of such systems, e. g., Frege's propositional calculus, being shown to be non-independent. Equivalence and non-equivalence of systems are discussed in the same context. The deduction theorem is proved in Chapter 3 for all the axiomatic propositional calculi in the book.\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Paperback","offer_id":45283064545431,"sku":"9789401035491","price":3633.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9789401035491.webp?v=1769303977","url":"https:\/\/atlanticbooks.com\/products\/systems-of-formal-logic-9789401035491","provider":"Atlantic Books","version":"1.0","type":"link"}
