Leslie Charteris said this quote

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.
