Criticism is the act or art of analyzing and evaluating or judging the quality of a literary or artistic work, musical performance, art exhibit or dramatic production. It can be used as a critical comment, article, or essay.
Inappropriate or baseless criticism can be a characteristic of liberal style.
Appropriate criticism, is on the other hand, a tool with which conservatives learn and improve themselves. One of the greatest Christian virtues, that atheists often lack, is the humility to make good use of substantive criticism.
