Funny that people are rarely ever satisfied to accept supposedly "built-in" limitations in other areas of human experience. Even when there are limitations, athletes, physicians, thinkers, and others can certainly push the envelope as to what is humanly possible. For all I can be certain of, pervasive irrationality could have been deliberately bred into people over time, not unlike other limiting adaptations such as dachshunds physiology. How long did that take?
I do not doubt that there are certain limitations to human perception and cognition, but this hardly rationalizes the notion of deciding that knowledge and reason are not worthwhile.
