We live in an age when everyone is a critic. "Criticism" is all over the Internet, in blogs and chat rooms, for everyone to access and add his two cents’ worth on any subject, high or low. But if everyone is a critic, is that still criticism Or are we heading toward the end of criticism If all opinions are equally valid, there is no need for experts. Democracy works in life, but art is undemocratic. The result of this ultimately meaningless barrage is that more and more we are living in a profoundly-or shallowly-uncritical age.
A critic, as T. S. Eliot famously observed, must be very intelligent. Now, can anybody assume that the invasion of cyberspace by opinion upon opinion is proof of great intelligence and constitutes informed criticism rather than uninformed artistic chaos
Of course, like any self-respecting critic, I have always encouraged my readers to think for themselves. They were to consider my positive or negative assessments, which I always tried to explain, a challenge to think along with me: here is my reasoning, follow it, then agree or disagree as you see fit. In an uncritical age, every pseudonymous chat-room chatterbox provides a snappy, self-confident judgment, without the process of arriving at it becoming clear to anyone, including the chatterer. Blogs, too, tend to be invitations to leap before a second look. Do the impassioned ramblings fed into a hungry blogosphere represent responses from anyone other than long-heads
How has it come to this We have all been bitten by television sound bites that transmute into Internet sound bytes, proving that brevity can also be the soul of witlessness. So thoughtlessness multiplies. Do not, however, think I advocate censorship, an altogether unacceptable form of criticism. What we need in this age of rampant uncritical criticism is the simplest and hardest thing to come by.. a critical attitude. How could it be fostered For starters, with the very thing discouraged by our print media: reading beyond the hectoring headlines and bold-type boxes embedded in reviews, providing a one-sentence summary that makes further reading unnecessary. With only slight exaggeration, we may say that words have been superseded by upward or downward pointing thumbs, self-destructively indulging a society used to instant self-gratification.
Criticism is inevitably constricted by our multinational culture and by political correctness. As society grows more diverse, there are fewer and fewer universal points of reference between a critic and his or her readers. As for freedom of expression. Arthur Miller long ago complained about protests and pressures making the only safe subjects for a dramatist babies and the unemployed.
My own experience is that over the years, print space for my reviews kept steadily shrinking, and the layouts themselves toadied to the whims of the graphic designer. In a jungle of oddball visuals, readers had difficulties finding my reviews. Simultaneously, our vocabulary went on a starvation diet. Where readers used to thank me for enlarging their vocabularies, more and more complaints were lodged about unwelcome trips to the dictionary, as if comparable to having to keep running to the toilet. Even my computer keeps questioning words I use, words that can be found in medium-size dictionaries. Can one give language lessons to a computer What may be imperiled, more than criticism, is the word.
I keep encountering people who think "critical" means carping or fault-finding, and nothing more. So it would seem that the critic’s pen, once mightier than the sword, has been supplanted by the ax. Yet I have always maintained that the critic has three duties: to write as well as a novelist or playwright; to be a teacher, taking off from where the classroom, always prematurely, has stopped, and to be a thinker, looking beyond his specific subject at society, history, philosophy. Reduce him to a consumer guide, run his reviews on a Web site mixed in with the next-door neighbor’s pontifications, and you condemn criticism to obsolescence. Still, one would like to think that the blog is not the enemy, and that readers seeking enlightenment could find it on the right blog just as in the past one went looking through diverse publications for the congenial critic. But it remains up to the readers to learn how to discriminate.

It can be concluded from the last paragraph that the author ______.

A．probably agrees that the blog is the enemy

B．fails to advise advice readers to seek enlightenment on any of the blogs

C．never thinks that blogs will have the similar features (as that of the traditional publications)

D．encourages the readers to make independent judgment
