本月一道AA寂静: argument:一个地方的sports center 开了个游泳池,夏天的时候有百分之二十的会员增长,为了增加会员数目和费用,于是他们决定要多开发各种项目像:tennis court,然后又说他们是这个地区里唯一一个有这些项目的,是有competitive advantages 的。
原题:The following appeared as part of a business plan created by the management of the Take Heart Fitness Center:
“After opening the new swimming pool early last summer, Take Heart saw a 12 percent increase in the use of the center by its members. Therefore, in order to increase membership in Take Heart, we should continue to add new recreational facilities in subsequent years: for example, a multipurpose game room, a tennis court, and a miniature golf course. Being the only center in the area offering this range of activities would give us a competitive advantage in the health and recreation market.”(102)
思路: 1. 忽略他因。---新建Swimming pool不是带来增长的唯一原因 2. 错误类比。--Swimming pool 和其他facilities 相比 3. 收入和支出--添加新设施可能带来成本增长,提高价格,所以不一定会是优势
问题就来了。我第一点已经反驳了swimming pool作为带来增长的原因,那么在写第二点的时候,又是在承认swimming pool的基础上,把swimming pool 和其他facilities 比较。这样先反驳,又认可在逻辑上有没有问题?但是不是先写错误类比,再排除他因,逻辑上就正确了???
我已近发现在很多AA中,但凡同时出现错误类比和忽略他因两种错误是,上述问题都会存在。请NN们解答。。。
