From this great cloud of witnesses I have omitted all those leaders of thought and morals, “friends of the wise and teachers of the good” supporters of this great cause who are living. I followed a like reserve in my “Memories,” making in them none but passing allusions to famous persons still alive. I do not share the modern journalistic habit of uninvited public intrusion upon living people who may very well be unwilling at the moment to be dragged into controversy or exposed to insult; and every one knows that the vivisectors and their friends have no manners, and flout all the Hague conventions of debate.
