To announce that there must be no criticism of the President, or that we are to stand by the President, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public. Nothing but the truth should be spoken about him or any one else. But it is even more important to tell the truth, pleasant or unpleasant, about him than about any one else.
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.
I wouldn't be worth my salt if I weren't attracting some controversy and criticism. Everyone in the world who has done something in life has attracted criticism.
O why do I ever let anyone read what I write! Every time I have to go through a breakfast with a letter of criticism I swear I will write for my own praise or blame in future. It is a misery.
It's useful for activists just to be out there to keep you mindful and not get complacent, even if ultimately you think some of their criticism is misguided.
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.
