The liberal holds that he is true to the republic when he is true to himself. (It may not be as cozy an attitude as it sounds.) He greets with enthusiasm the fact of the journey, as a dog greets a man’s invitation to take a walk. And he acts in the dog’s way, too, swinging wide, racing ahead, doubling back, covering many miles of territory that the man never traverses, all in the spirit of inquiry and the zest for truth. … When the two of them get home and flop down, it is the liberal–the wide-ranging dog–who is covered with burdocks and with information of a special sort on out-of-the-way places. Often ineffective in direct political action, he is the opposite of the professional revolutionary, for, unlike the latter, he never feels he knows where the truth lies, but is full of rich memories of places he has glimpsed it in. He is, on the whole, more optimistic than the revolutionary, or even the Republican in a good year.
