Either criticism is no good at all (a very defensible position) or else criticism means saying about an author the very things that would have made him jump out of his boots.
Reviewers are usually people who would have been, poets, historians, biographer, if they could. They have tried their talents at one thing or another and have failed; therefore they turn critic.
I am more afraid of deserving criticism than of receiving it. I stand in awe of my own opinion. The secret demerits of which we alone, perhaps, are conscious, are often more difficult to bear than those which have been publicly censured in us, and thus in some degree atoned for.
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.
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.
