一个名词用得多了,就很难准确定义。如凳子,说能坐的是凳子?砖头也能坐。又如问题,说问题是必须解决的事儿?那只是-1→0型问题;说它是解决更好的或理想与现实的差距?那也只是0→+1型问题。每当遇到这种情况,与其笼统定义,还不如先分类后界定好。 人们早就发现,分类有助于清晰。这里只谈分类中存在的两点不足。第一,多注意对有形的如对商品的分类,少留心对无形的如对问题的分类;第二,多沿用常规方法分类,很少用新的思路分类。
A term used much more difficult to accurately define. As a stool, that can sit stool? Brick can sit. Another example is the question, that is, the problem must be solved? It is only -1 → 0 type of problem; that it is to solve better or the ideal and the reality of the gap? It is only 0 → +1 type of problem. Whenever encountered this situation, rather than its general definition, not as good as the first classification defined. It has long been discovered that classification helps clarity. Here only talk about the existence of two points deficiencies. First, pay more attention to the tangible as the classification of goods, pay less attention to the intangible such as the classification of the problem; the second, more classification by conventional methods, rarely with new ideas classification.
