柏拉图“理念论”如何形成的假说

写读书笔记，结果整理出了一套假说（当然没有什么史料证据），用以解释柏拉图“理念论”的形成。以下为读书笔记。

Lives of The Eminent Philosoohers, Diogenes Laertius

从书柜里随机抽出来的，翻翻柏拉图这章。Diogenes一个公元后200年的罗马人，也不知道哪里搜集的资料，还用了一条线索，整理出了柏拉图“理念论”的形成逻辑。

我的理解如下：

第一步、根据认识途径，对“存在”进行二元划分。

1, everything senses is constantly changing and this is fearsome and ridiculous because if so, everything is always “becoming” and nothing “is”/exists.

2, there is something that exists

3, there is something that exists and cannot be sensed

4, things can either be sensed or thought

5, by 1,2,3,4, things that “are”/exist can only be thought

6, it is ridiculous that a thing can be both “sensed” and “thought”.

C, by 5,6, there exist two category of things: one kind can only be thought while the other kind can only be sensed

上述逻辑完成了对“存在”的二元划分

第二步、从本体论角度，分别解释由认识方式不同而二元划分的两类存在

1, Things that are thought are “ideas”（理念）

2, Things that are thought exist/will not change/are eternal （从第一步）

C1, by 1,2, ideas exist/will not change/are eternal

1, Things that are sensed are “ordinary objects” like tables and chairs

2, things that are sensed always change/do not exist/are becomings （从第一步）

C2, by 1,2, ordinary objects like tables and chairs are becomings/always change/do not exist

第三步、进一步细化“理念”

1, there are more than one distinct “ideas” （柏拉图男人的直觉lol)

2，”Ideas” include “justice”, “beauty”, “goodness”, etc.

第四步、重新建立被二元切割的两种存在之间的关系

ordinary objects are simulations of ideas such that if a thing is sensed as beautiful than it simulates the idea of beauty in some degree

第五步、进一步澄清什么是think、什么是sense，以及各种中间态

我猜测，柏拉图只会认为数学般抽象、逻辑的思维，才叫think；sense只需要用纯粹的感官体验来定义即可

第六步、澄清介于理念idea和日常事物之间的各种perceptible、conceivable的东西

由此六步，柏拉图理念论的大厦就建立起来了。虽然我不信这套吧hhhh
