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.
Never do a single thing in the anticipation to prove something to someone who has hurt you. If someone has hurt or offended you (whoever that person may be), never perform anything or strive for anything in your life with the mind of proving something to that someone/ to those people. May nothing that you do be done with any thought of them in mind. There is nothing that needs to be proven.
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.
