凡物之然也，必有故。而不知其故，虽当，与不知同，其卒必困。
释义Explanation
这句话指出，任何事物的存在和状态都有其内在原因。如果不了解背后的因果，即便偶然做对了，也等同于无知，最终必然陷入困惑与失败。它提醒我们：做事不能只凭运气或表面经验，而应深究规律、理解成因，才能稳定地获得正确结果，避免在变化中迷失。
This saying points out that every state of affairs has an underlying cause. If one does not understand the cause, then even an accidental correct result is no different from ignorance, and in the end one will surely be trapped by difficulties. It reminds us that we should not rely on luck or superficial experience; rather, we must investigate the underlying laws and causes. Only by grasping the deeper reasons can we consistently obtain the right results and avoid being lost in changing circumstances.
使用场景Usage
在职场中，某人偶然用一套方法做成项目，便以为找到了捷径，却不深究成功背后的行业规律与用户需求。当环境变化，旧方法失效，他因不知其所以然而陷入困境。这句古语提醒我们，日常复盘与因果分析比运气更重要。
In the workplace, a person may succeed once by chance and mistake luck for a shortcut, without understanding the underlying logic of the market or client needs. When circumstances change, the same method fails, and because they never understood why it worked, they fall into trouble. This ancient saying reminds us that reviewing causes and analyzing reasons is more important than relying on luck.
