"The present state of things is the consequence of the former, and it is natural to inquire what were the sources of the good that we enjoy, or of the evil that we suffer. If we act only for ourselves, to neglect the study of history is not prudent: if we are entrusted with the care of others, it is not just. Ignorance, when it is voluntary, is criminal; and he may properly be charged with evil who refused to learn how he might prevent it."
Samuel Johnson, Rasselas.
