“Few can be induced to labor exclusively for posterity; and none will do it enthusiastically. Posterity has done nothing for us; and theorize on it as we may, practically we shall do very little for it, unless we are made to think we are at the same time doing something for ourselves.”
“Men of genius are not to be analyzed by commonplace rules. The rest of us who have been or are leaders, more commonplace in our quality, will do well to remember two things. One is never to forget posterity when devising a policy. The other is never to think of posterity when making a speech.”
