Proof Theory of N4-Paraconsistent Logics

The current publication is the 1st monograph ever with a relevant specialize in the facts concept of paraconsistent logics within the area of the four-valued, confident paraconsistent good judgment N4 through David Nelson. the amount brings jointly a few papers the authors have written individually or together on quite a few platforms of inconsistency-tolerant good judgment.

Further it can here be inferred that the class of all individuals is not in a one-to-one correspondence with the class of unit sets. Other anomalies have appeared by a recent publication of E. Specker [1953]. The system here presented follows nearer the line of Zermelo's axiomatics. From the development of axiomatic set theory in the meantime it adopts some devices. e, using the formal language of logic. By this way it becomes possible to formalize the system in the frame of the predicate calculus of first order with admitting besides formal axioms also axiom schemata.
