The idealist's program of political or economic reform may be impracticable, absurd, demonstrably ridiculous; but it can never be successfully opposed merely by pointing out that this is the case. A negative opposition cannot be wholly effectual: there must be a competing idealism; something must be offered that is not only less objectionable but more desirable.
I am an absurd idealist. But I believe that all that must come true. For, unless it comes true, the world will be laid desolate. And I believe that it can come true. I believe that, by the grace of God, men will awake presently and be men again, and colour and laughter and splendid living will return to a grey civilisation. But that will only come true because a few men will believe in it, and fight for it, and fight in its name against everything that sneers and snarls at that ideal.
Many have dreamed up republics and principalities that have never in truth been known to exist; the gulf between how one should live and how one does live is so wide that a man who neglects what is actually done for what should be done learns the way to self-destruction rather than self-preservation.
