“ Within the last two centuries, a number of words of honest origin have passed into an opprobrious sense; for example, the oppressed tenants of Ireland are spoken of by Spenser and Sir John Davies as "villains." In our version of the Scriptures, "cunning" implies merely skill in music and in art. Shakspeare employs the word "vagabond" as often to express pity as reproach; and I think it will be found, that as a knave, prior to the reign of Elizabeth, meant merely a serving man, so a blackguard was the name for a pot-boy or scullion in the reign of Queen Anne. ”
