37Woven baskets characterized by a particular distinctive pattern have previously been found only in the immediate vicinity of the prehistoric village of Palea and therefore were believed to have been unique to the Palean people. Recently, however, archaeologists discovered such a "Palean" basket in Lithos, an ancient village across the Brim River from Palea. The Brim River is very deep and broad, and so the ancient Paleans could only have crossed it by boat, but there is no evidence that the Paleans had boats. And boats capable of carrying groups of people and cargo were not developed until thousands of years after the Palean people disappeared. Moreover, Paleans would have had no need to cross the river—the woods around Palea are full of nuts, berries, and small game. It follows that the so-called Palean baskets were not unique to Palea.
In this argument the author claims that the founding of a "Palean" basket in Lithos can prove that the Palean baskets are not unique in Palean. To substantiate the conclusion, the arguer points out that the Brim river which between the two countries is too deep to cross without a boat and there is no evidence can prove the Paleans had boats. In addition, the boat which can carry cargo and groups of peoples was not developed at that time. Furthermore, the Paleas need not to cross the river because there are full of fruits, nuts and small game in their place. The line of reasoning is unconvincing for a couple of reasons.
To start with, the arguer fails to rule out the possibility that the Paleans crossed the river. Though still now there is no evidence can prove that the Paleans have boat, it do not mean to there will be no any evidence can be found in the future. It is possible that the evidences were embedded by the earthquake happened thousands of years ago. Another flaw is that the arguer takes a assumption that it is beacuse the Paleans had no big boat which can carry groups people and cargo that they cannot across the Brim river. Without the big boat, the Paleans can cross the river buy other kinds of boat such as raft. Even if we granted that the Paleans had no any boat, there still other ways they can across the river. For example, there was a cordage bridge between each side of the river, people can easily across the river by it. The arguer commits a fallacy of unwarranted assumption to assume that no big boat there is no way to across the deep and broad Brim river.
Similarly, the arguer oversimplifies the reasons why the Paleans should across the river to arrive in the Lithos though they had all kinds of nuts, fruits and small game in their place. The exploration is the nature ability to human being. The paleans maybe so curious to another side of the river, and they want to take a risk. It is also possible there was new kind of grain in Lithos, the Paleans wanted to grow them by exchange it with their baskets. The evidence provided in this argument is not sufficient to valid the author's assumption.
Last but not the least, there is no proof that thousands of years ago the river was as deep and broad as it is today. Maybe in prehistoric era the river was so shallow that the Paleans can across it by their feet. With the time passing, the river became deeper and deeper which cannot be easily across anymore. Without the geography evidence which can prove that the Brim river has not any change until now, we cannot believe what the author claims.
As it stands, the argument is not persuasion as it stands. To make the argument more persuasive ,the arguer world have to prove that there is no other way to cross the river. Moreover, there still need some information concerning the geography changes had never happened and the Paleans never want to across the river. |
