Final answer:
According to Aristotle, the efficient cause of man is the agent or force that gives man his specific form or shape. It is comparable to how a sculptor shapes a sculpture.
Step-by-step explanation:
Aristotle's efficient cause of man refers to the agent or force that gives man his specific form or shape. In the context of man, Aristotle believed that the efficient cause is the ability and artistic skill of the sculptor. Just as a sculptor shapes a sculpture, the efficient cause of man is responsible for giving man his unique characteristics and abilities. This concept is part of Aristotle's doctrine of the four causes, which aims to explain the nature of things by answering four basic questions.
