 Here a subject s can deductively infer Q1 from P1 given some background  information.[1]  Suppose s acquires justification for P1 by learning E1. In this case s will also acquire justification for Q1 in virtue of her knowledge of the inferential relation from P1 to Q1 and her justification for  P1.[2]  Thus s’s justification for P1 will transmit to Q1.
