[알쏭달쏭~]

The purpose of ethics is to define a person’s proper values and interests and the actions which he should take in regard to those interests. If an individual has no interests, no values with which to concern himself, then any discussion regarding ethics becomes as useless as contemplation of how many angels will fit on the head of a pin.

위 문장 중에 이 부분이 이해가 잘 안됩니다.>>>how many angels will fit on the head of a pin

천사와 핀이 무슨 연관이 있나요? 아니면 관용어구 인가요?

 부탁 드립니다
