  • In this paper, we explore the concept of a logic which proceeds by trial-anderror, and deduce consequences which follow from relatively weak assumptions about these experimental logics. One of the consequences (Theorem 2) is analogous to, and in a rigorous sense it extends, Godel’s First Incompleteness Theorem. A second result (Theorem 5) stands in contrast to the corresponding result for ordinary formal systems, since it is not in general possible to mechanically find true but unprovable… CONTINUE READING
