Conclusive Reasons Condition

The conclusive reasons condition was offered by Fred Dretske. Dretske argued that person A knows that X if person A has reason R for X, in such a way that if X were not the case, person A would not have reason R.

This was given as defence against the second Gettier case (the person with ten coins in his pocket will get the job). However, it miserably fails our second scenario, which involves the perceptual issue above with Mrs. Knull and her secretary.
