Mencius 6A.12: the bent finger and moral self-examination
A bent fourth finger with a deficient heart to show that people often rush to fix visible defects while tolerating deeper failures of judgment.
孟子曰：「今有無名之指，屈而不信，非疾痛害事也。如有能信之者，則不遠秦、楚之路，為指之不若人也。指不若人，則知惡之；心不若人，則不知惡。此之謂不知類也。」
Mencius said, 'Here is a man whose fourth finger is bent and cannot be stretched out straight. It is not painful, nor does it incommode his business, and yet if there be any one who can make it straight, he will not think the way from Qin to Chu far to go to him; because his finger is not like the finger of other people. When a man's finger is not like those of other people, he knows to feel dissatisfied, but if his mind be not like that of other people, he does not know to feel dissatisfaction. This is called "Ignorance of the relative importance of things."'

Central question
Why does Mencius use a bent finger to talk about cultivating the heart?
Direct answer
Because people quickly care about minor visible defects, yet may tolerate serious defects of judgment and character for years. The analogy exposes a disordered sense of priority.
First principle
Real self-examination is not only about fixing what can be seen. It is about reordering what deserves urgent repair.
Why it matters
This passage carries the doctrine of human goodness into the level of practice: if the heart can be made better, then neglecting it is already a failure of judgment.

Citation note
The key line is not the finger itself but the final charge of 'not knowing how to classify.' The passage is about moral priority, not anatomical oddity.
