It is the beginning of all true criticism of our time to realize that it has really nothing to say, at the very moment when it has invented so tremendous a trumpet for saying it.
The sceptic will say, 'It may well be true that this system of equations is reasonable from a logical standpoint, but this does not prove that it corresponds to nature.' You are right, dear sceptic. Experience alone can decide on truth.
There is a difference between responsible criticism that aims for success and defeatism that refuses to acknowledge anything but failure. Hindsight alone is not wisdom, and second-guessing is not a strategy.

But what help from these fineries or pedantries? What help from thought? Life is not dialectics. We, I think, in these times, have had lessons enough of the futility of criticism.
It is the will of God that we must have critics, and missionaries, and Congressmen, and humorists, and we must bear the burden. Meantime, I seem to have been drifting into criticism myself. But that is nothing. At the worst, criticism is nothing more than a crime, and I am not unused to that.
