Care to elaborate on the essence of concepts, If it's not visible, what would it be?

According to a major school of thought in psychology and philosophy, concepts exist separately from their various sensory, motor, and affective representations.

Using a triangle example, Kemmerer in Concepts in the Brain (pp. 253-254, Oxford University Press) says,

 

In geometry class, when we draw a general triangle, we're bound to draw a triangle that's either right, or acute, or obtuse, but cannot draw general one.In that case, in what form does the general triangle exist?

Can you show some evidence to support this? It's not really an acceptable observation to base a discussion on if others disagree.

 

Sure, when I inagine what a circle look like, my mind always provides me a circle as same as one drawn on paper, and the circle always has its specific diameter of 3cm or 4cm. Arrording to Kant's theory, the reason why a man can spot a circle is because he has got the scheme of it. I wonder if we can know what a general circle or, as mentioned,  the scheme look like.

I don't know what "learn the existence of concept" means.

cross out "the existence"

头脑中的概念不是视觉实体。当您尝试形象化一个概念时，您会得到它的视觉表示。概念不同于它们的视觉表示。

 

So in what way does the human learn the existence of concept?

什么是“概念概念”，它与概念有何不同？  

在将“圆”视为几何概念时，我们没有做的一件事是考虑特定的大小。这就是对对象进行抽象思考的要点：它剥离了具体的品质，留下了核心意义，即所有这些对象共有的意义。所有圆的共同点是一条与中心点保持恒定距离的连续线。

Actually that is a typo, the big idea is that can the common of circles, as you mentioned, be visualized? If not, how can we know that? My answer is not, since when you want to represent the"constant distance" in picture, it has to be in specific size, 3cm or 4cm etc. Not a general notion.

在您的 OP 中，您从一个圆圈开始，然后询问两个圆圈。在上面的解释中，只有一个圆圈。你为什么要发明一个“一般”圈子？

That's because the general one acts as the standard of circle and it must exclude irrelevant factors like color and size. Definitely this is not visible but more of a form.

当你用铅笔在一张纸上画一个圆时，它也有特定的颜色、线宽、石墨厚度、底色、电导率、温度等。我们可以忽略这些。同样，我们也可以忽略它的大小，而专注于它的几何形状。

That's where I agree with you. But the point is, how do we neglect that

Sure, you can just draw a circle on a piece of paper, directly you'll see it is a circle 2cm or some other length in diameter. It depends on your what you think

Picture a circle in mind, and you'll always find it is a circle with specific size. In that case, how do we know the general circle from specific circle?
