We can start out by talking about the three parts of the human mind that Freud believed in.
1. The ID is all about our desires, and the things that we want to do, in order to make ourselves feel happy.
2. The EGO is all about reality, and knowing the difference between what is possible/socially acceptable, and what is not possible.
3. The SUPEREGO is all about morals, and knowing the difference between right & wrong. The difference between justice and injustice.
So, read the question again. Which one do you think fits in this example? Id, Ego, or Superego?
