For appreciating an art you need the eye of an artist. It means that if we want to comment on any issue, art work, consumer product or on any product we must always keep in mind that someone has put in a lot of efforts and invested time to come out with this piece of art. By saying piece of art it doesn’t mean a drawing or a sculpture, even an electronics item or machinery is a piece of art. The stated line means, if we wish to appreciate or even condemn the work done by the other person then we should have in depth understanding of the subject.
We all know making a sculpture is a tedious job. The artist takes a lot of efforts to make it; they have to start from selecting the rock then slowly but gradually cutting it to the right shape and size. Later they need to polish it to bring it to a recognizable shape. In this complete procedure even if there is a small mistake it would cost a lot not only in money but in time too. Hence if a sculpture needs to commented on then is best if a sculpture comments because he would be the one who can actually appreciate it in a genuine manner.
In order to comment on a art it not a compulsion that the person must have through knowledge about the subject. If we need to comment on the kind of food the only prerequisite is a tongue. Now it is upon them if they like it or not some people might relish the food some might not. Its not necessary for a person to know how to cook for commenting on the taste of the food.
For commenting on anybody’s work, its important to comment in a manner that we never demoralize the person if the work is not as expected it to be. If the work is good then appreciate it in a manner that the artist does an even better work next time.
Hence its totally dependent on the art that we are looking at and wish to comment on that it needs our expertise or not. Appreciating the external beauty might not need the deep knowledge about it. Expertise in the field is the right person to comprehend the true worthiness of the art.
