The man who loves his nation can prove the sincerity of this sentiment only by being ready to make sacrifices for the nation's welfare. There is no such thing as a national sentiment which is directed towards personal interests. And there is no such thing as a nationalism that embraces only certain classes. Hurrahing proves nothing and does not confer the right to call oneself national if behind that shout there is no sincere preoccupation for the conservation of the nation's well-being.
