Problematic Axioms and Rules of Standard Logic
Feasible Inference Rules of Logic
Guidelines for an Adequate Logic
- Principle of locality (admittance of contradictions)
- Opportunistic logic (fusion of different logical approaches)
- Associatively guided search (warranting a semantic coherence)
- Substitution of truth values by degrees of trustworthiness
A A B Extension Rule A A B Ex falso quodlibet ( A) A Law of Double Negation A A Law of the Excluded Third
Modus ponens Abduction Syllogisms
A B x R(x) H(x) A B A B x M(x) R(x)---------- ---------- ------------------------B A x M(x) H(x) (more trust- („ferio“) worthy)
