The art of manipulating public opinion, which is a necessary art for the democratic politician, and, like other arts, is sometimespractised with greater virtuosity by knaves than by honest men (who are apt to disdain it), has a different technique in different countries. For instance, in England we excel in whitewashing: in America they excel in tarring and feathering. We strain our nerves and stretch our consciences to avoid a scandal: Americans do the same to make one.
