What visual artists like painters want to teach is easy to make out but difficult to explain, because painters translate their experience into shapes and colors, not words.They seem to feel that a certain selection of shapes and colors, out of the countless billions possible, is exceptionally interesting for them and worth showing to us.Without their work we should never have noticed these particular shapes and colors, or have felt the delight which they brought to the artist. Most artists take their shapes and colors from the world of nature and from human bodies in motion and at rest; their choices indicate that these aspects of the world are worth looking at, that they contain beautiful sights.Contemporary artists might say that they merely choose subjects that provide an interesting pattern, that there is nothing more in it.Yet even they do not choose entirely without reference to the character of their subjects. If one painter chooses to paint a decaying leg and another a lake in moonlight, each of them is directing our attention to a certain aspect of the world.Each painter is telling us something, showing us something, emphasizing something—all of which means that, consciously or unconsciously, he is trying to teach us. 1.An artist hopes that the public will ____. A.understand him and learn from him B.notice only shapes and colors in his work C.teach him something D.believe what he says in his work 2.It is hard to explain what a painter is saying, because he/ she ___.

B.Art is merely the arranging of shape and color. C.Every artist tries to say something to the public. D.One must look beyond shape and color to find what the artist is saying.

2. If man's mind cannot be turned into a logic-machine, neither can it function properly as a great emotional sponge, to be squeezed at will. All of us have known people who gush as a general response to life——who gush in seeing a sunset, who gush in reading a book, who gush in meeting a friend. They may seem to live by emotion alone, but their constant gushing is a disguise for absence of genuine feeling, a torrent rushing to fill a vacuum. It is not uncommon to find beneath the gush a cold, analytic mind that is astonishing in its meticulousness and ruthless in its calculation. Somewhere between machine and sponge lies the reality of the mind——a blend of reason and emotion, of actuality and imagination, of fact and feeling. 3. The entanglement is so complete, the mixture so thoroughly mixed, that it is probably impossible to achieve pure reason or pure reason or pure emotion, at least for any sustained period of time. 4. It is probably best to assume that all our reasoning is fused with our emotional commitments and beliefs, all our thoughts colored by feelings that lie deep within our psyches. Moreover, it is probably best to assume that this stream of emotion is not a poison, not even a taint, but is a positive life-source, a stream of psychic energy that animates and vitalizes our entire thought process. 5. The roots of reason are embedded in feelings——feelings that have formed and accumulated and developed over a lifetime of personality-shaping. These feelings are not for occasional using but are inescapable. To know what we think, we must know how we feel. It is feeling that shapes belief and forms opinion. It is feeling that directs the strategy of argument. It is our feelings, then, with which we must come to honorable terms.

There is no royal road to science and only those who do not dread the fatiguing climb of its steep paths have a chance of gaining its luminous summits.
