In this argument, the arguer concludes that ancient Kalinese artists used molds of actual bodies, not sculpting tools and techniques, to create these statues. In addition, the arguer reclaims that the value of life-size sculptures would decrease while miniature would increase. On the surface, the argument seems logical, however, in fact, the argument based on merely unwarranted assumption and doubtful evidences.
Firstly, The author attempts to establish a causal relationship between the fact that archeologist have recently discovered modes of human heads and hands on kali and the claim that the ancient Kalinese artists used molds of actual bodies, not sculpting tools and techniques, to create life-size statues. However, it may be not the case. The author provides no evidences that the modes of human heads and hands found on kali were used to sculpt life-size statues. Even though we admit that the modes was used to create statues, there are not enough evidence for us to convince that it is these modes that make the ancient clay statues. It is possible that they do not exist on the same period of time. Even if the ancient artists use these modes to make the status, we can not come to the conclusion safely that artists only use modes but not sculpting tools and techniques to create these statues, because the arguer does not offer us relative information. Thus, without enough explanations the author can not convince me that the discovery of modes on kali result in the assert that artist used modes but not other tools.
Secondly, the author unfairly assumes the phenomena that molds could only used for life-size sculptures bears some to the fact that kalinese miniature statues were abstract and entirely different in style. Nevertheless, the author provides no evidence to support that this is the case nor does the author establish a causal relationship between them. It is possible that the life-size statues and the miniature did not appear in the same period of time in the history, therefore their style is absolutely different.
Thirdly, the author commits a fallacy of hasty generalization that collectors should expect the life-size sculpture to decrease in value and the miniatures to increase. However, it is not the case if life-size statues are far less than the miniatures. it is also possible that life-size statues have more research value while the miniatures mean nothing for us. Thus, the author can not conclude that confidently.
To sum up, the argument is not persuasive as it stands. To make the argument more convincing the arguer would have to take the following conditions into consideration: the use of the discovered modes; the correct time of modes, life-size statues and miniatures and so on.
