The prime intent of Cognitive Complications is one of innovation. Rescher addresses issues that are under-examined in the present state of discussion, their inherent interest notwithstanding. The linking thread of these investigations is their pragmatic dimension, inherent in the idea that rational inquiry is itself a practice—albeit one that functions in the ideationally cognitive rather than physically manipulative realm. And as a practice it has its aims and functions which in their turn provide for the standards of adequacy and efficacy that establish the criteriological norms of our cognitive proceedings.
