Validity of Practical Inference
Berislav Zarnic

Abstract:
The paper develops a dynamic framework suitable for analysis of
practical reasoning. The application of functional approach in dynamic
semantics confirms the results obtained in philosophical analyses of
practical inference, regarding, in particular, defeasibility,
undetachability and distinctive quality of conclusion. Contrdictory
results of proposed tests of validity and conflicting intuitions on
valid forms of practical inference are reconciled.
