Perhaps you can think of a sudden stop to the bench and enough to the vase, which is the most critical step, often referred to as the inspiration (similar to the phenomenon of biological mutations, changes that have taken place here is to change the stool is so used to sitting concept), do this step you have to be "stool" and "their own bodies," the two concepts linked in the minds of, and conducted a pilot course of thinking: First of all, looked at the high stool, probably determine the If we stand on the next top is likely to be enough on a vase, and they feel that they can certainly climb up stool.

你突然想到也许可以通过站到凳子上而够到花瓶，这是最关键的一步，通常称为灵感（这个现象类似于生物中的突变，这里发生的变化是改变了凳子只是用来坐的这样的观念），做到这一步时你已经将&凳子&和&自己的身体&这两个概念在头脑里联系起来了，并且进行了一个思想试验过程：首先看了看凳子的高度，大概判断了下自己如果站在上头很可能就可以够着花瓶了，并且觉得自己肯定可以爬到凳子上去。
