Criticism is the disapproval of people, not for having faults, but having faults different from your own.

Unknown

Neither praise nor blame is the object of true criticism. Justly to discriminate, firmly to establish, wisely to proscribe, and honestly to award - these are the true aims and duties of criticism.

Simms

In my wide association in life, meeting with many and great men in various parts of the world, I have yet to find the man, however great or exalted his station, who did not do better work and put forth greater effort under a spirit of approval than he would ever do under a spirit of criticism.

Charles M. Schwab

We are suffering from too much sarcasm.

Marianne Moore

Doubtless criticism was originally benignant, pointing out the beauties of a work rather that its defects. The passions of men have made it malignant, as a bad heart of Procrustes turned the bed, the symbol of repose, into an instrument of torture.

Henry Wadsworth Longfellow

US poet (1807 - 1882)

Ours is an age of criticism, to which everything must be subjected. The sacredness of religion, and the authority of legislation, are by many regarded as grounds for exemption from the examination by this tribunal, But, if they are exempted, and cannot lay claim to sincere respect, which reason accords only to that which has stood the test of a free and public examination.

Immanuel Kant

German philosopher (1724 - 1804)

It is a barren kind of criticism which tells you what a thing is not.

R. W. Griswold

Most of our censure of others is only oblique praise of self, uttered to show the wisdom and superiority of the speaker. It has all the insidiousness of self-praise, and all the ill-desert of falsehood.

Tyron Edwards

If you believe in what you are doing, then let nothing hold you up in your work. Much of the best work of the world has been done against seeming impossibilities. The thing is to get the work done.

Dale Carnegie

A good writer is not necessarily a good book critic. No more so than a good drunk is automatically a good bartender.
