Lewis: Those who do not learn from past mistakes - their own and those of others - are condemned to repeat them. In order to benefit from the lessons of history, however, we first have to know history. That is why the acquisition of broad historical knowledge is so important.
Morris: The trouble is that the past is infinitely various. From its inexhaustible storehouse of events it is possible to prove anything or its contrary.
The issue that Morris raises in objecting to Lewis' view is whether
(A) there are any
uncontested historical facts - WRONG. Lewis suggests that History may help but Morris says that may not be so helpful but none Point out any specific facts.
(B) historical knowledge can be
too narrow to be useful - WRONG. Exactly opposite to Morris says.
(C) history teaches
any unequivocal lessons - CORRECT. Though didn't understand this in true sense but POE helped. All it can be said that one views history as a helping hand while another is not.
(D) there are
conventional criteria for calling a past action a mistake - WRONG. Nothing as such is discussed by Morris. There is no such argument on this from Lewis as well.
(E)
events in the present are
influenced by past events - WRONG. No not that. Nowhere it is suggested by Morris.
Answer C.
