on reasoning with ambiguities

... consequence rela- tion that holds for reasoning with ambiguities on the basis of an empirical discussion of intuitively valid arguments. The present paper starts out with such a discussion ... consequence relation comes with the rules of proof. Section 5 shows that it is no longer possible to use rules like Conditionalisation or Reductio ad Absur- dum when we deal with real ambiguities ... truth of the conclusion in (17) depends on the fact that it is derived from the conditional. It, the- refore, must be treated as correlated with the conse- quent of the conditional under any...
