I observe that a civilized age is more exposed to subtle sins than a rude age. Why? For this simple reason, because it is more fertile in excuses and evasions. It can defend error, and hence can blind the eyes of those who have not very careful consciences. It can make error plausible, it can make vice look like virtue. It dignifies sin by fine names; it calls avarice proper care of one's family, or industry, it calls pride independence, it calls ambition greatness of mind; resentment it calls proper spirit and sense of honour, and so on.
--Blessed John Henry Newman
