Argument107
The following appeared in an editorial in the Seatown newspaper.
"Seatown has a large port exclusively for fishing boats, whose owners pay fees for the upkeep of the docks and for facilities for cleaning engines and repairing nets. In recent years, declining fish populations have decreased fishing revenue and forced many owners to stop fishing altogether. As a result, the port has a high vacancy rate and port managers are considering allowing pleasure boats, including cruise ships and other large vessels, to use the port in order to increase revenue. But allowing pleasure boats into the port would be a mistake, because the fishing boats would be forced out of the port. We should preserve the port for the fishing fleet, which, unlike pleasure boats, contributes to the prosperity of Seatown."
提纲:
1 引进娱乐船只后渔船不一定要离开港口,没有必然联系,没有说明两种船只为什么不能共用港口
2 娱乐船只可以促进当地旅游业的发展,可以促进当地的繁荣
3 如果不引进娱乐船只,港口将逐渐闲置,使收入减少,这样也会影响当地的繁荣
正文:
In this argument, the arguer recommends that in order to keep the prosperity of Seatown, we should preserve the port for the fishing boats only. To support this conclusion the arguer points out that fish population has declined and the port has a high vacancy rate. Moreover the arguer reasons that the managers of the port tend to allow pleasure boats to use the port to raise income. As it stands, the argument suffers from several critical flaws as follows.
The major problem with this argument is that the author assumes that fishing boats will have to leave the port if pleasure boats are allowed. However, no evidence is stated in the argument to support this assumption. It is possible that travelers taking the pleasure boats are also interested in the course of fishing, and they can also go with the fishermen to enjoy the pleasure of fishing, which can be a practicable way of attracting tourists. Therefore, this argument is unwarranted without ruling out such possibility.
Another problem that undermines the logic of this argument is that only the fishing fleet can contribute to the prosperity of the town. The author commits a fallacy of hasty generalization. Even if fishing is the fundamental industry of the town, it does not follow that the newly built tourist industry cannot surpass it. Besides, the arguer does not provided any solid information concerning the average income of fishing. Without ruling out these and other possible factors, the author cannot confidently conclude that if they allow pleasure boats to the port the town will go through a recession.
Before I come to my conclusion, it is necessary to point out another flaw that weakens the argument. There is no thorough lost-benefit in this argument. If the increase of cost overweighs that of benefits, the town’s financial situation will fall in trouble of losing rather than gaining money. Also, the author neglects the fact that with the decreasing of fish population the income of the fishermen who pay for the upkeep will get fewer. It is sure that the vacant of the port will do nothing to help improve the town’s financial situation. So why not introducing the pleasure boats to make full use of the port?
To sum up, though the argument seems to be plausible, in fact, it is neither sound nor persuasive. Not only does it leave out such key issues, but also cites in the analysis the evidence, which does not lend strong support to what the arguer claims. To make the argument more convincing, the arguer would have to take the following conditions into consideration: why the fishing fleets would be forced out of the port after the pleasure boats arrive; and pleasure boats will not increase the revenue of the town as much as the fishing boats do. If the argument includes the given factors discussed above, it would have been more thorough and adequate. |
