In the paper, there is presented the theory of logical consequence operators
indexed with taboo functions. It describes the mechanisms of logical inference
in the environment of forbidden sentences. This kind of processes take place in
ideological discourses within which their participants create various narrative
worlds (mental worlds). A peculiar feature of ideological discourses is their
association with taboo structures of deduction which penalize speech acts. The
development of discourse involves, among others, transforming its deduction
structure towards the proliferation of consequence operators and modifying
penalty functions. The presented theory enables to define various processes of
these transformations in the precise way. It may be used in analyses of conflicts
between competing elm experts acting within a discourse.
